About hyperexponential (hx)
At hyperexponential, we’re building the AI-powered platform that enables the world’s most critical decisions in a $7 trillion industry, which risks to take, and how to price them. These are the decisions that shape real-world outcomes: whether rockets successfully launch into space, autonomous vehicles make it to market, or communities recover after major storms.
Until now, insurers have been making billion-dollar decisions using outdated tools. We’re changing that. Our platform brings together data, AI, and human expertise to give insurers the fastest path from submission to decision - helping them move faster, act smarter, and take on more risk with confidence.
Backed by a16z, Highland Europe, and Battery Ventures, we’re scaling globally - already trusted by nearly 50 of the world’s largest insurers, with zero churn and billions in premiums flowing through hx.
What began as a single product in one market has rapidly evolved into a multi-product, multi-territory platform powering every stage of pricing and underwriting. AI is at the core of what we do - from building the world’s first domain-specific AI peer programmer for insurance (think GitHub Copilot with a PhD in actuarial science) to shaping agentic workflows that reinvent how this industry operates.
What makes hx different is the people who build it. Here, impact isn’t tied to title or tenure; it’s defined by the challenges you take on and the discipline you bring. Surrounded by peers who stretch you, you’ll do the best, hardest work of your life in a company engineered to endure.
If that sounds like you, join us in building what comes next.
About Your Role
Engineering at hx tackles complexity that matters. Submission Triage is one of our most strategically important product areas, transforming how the world's largest insurers handle inbound submissions. Where carriers once relied on slow, manual processes to sort through documents, emails, and attachments, we're building AI-powered workflows that convert chaos into clarity - enabling underwriters to focus on the risks that matter most.
The Triage team sits at the intersection of ambitious product vision and technical depth. You'll work alongside Product, AI specialists, and client-facing teams to architect systems that ingest unstructured data from multiple channels, apply intelligent triage logic, and deliver actionable insights at speed. This isn't incremental improvement - it's reimagining how submission intake works in a market where every hour counts.
As a Senior Engineer, you'll own meaningful architecture decisions, shape product direction through engineering judgement, and see your work deployed into production environments at global insurers within weeks. Success here is measured in faster quote turnarounds, reduced manual effort, and revenue growth for one of hx's highest-priority products.
Check out our Engineering Candidate Hub for a behind the scenes look at the team you would be joining!
Your Senior Engineer Responsibilities
Design and build scalable backend architecture for Triage that handles diverse submission formats (Excel, PDF, Word, images, email) and converts unstructured data into structured, actionable fields with measurable improvements in processing speed and accuracy.
Partner directly with Product and clients to translate underwriting workflows into technical requirements, turning ambiguous problems into concrete system designs that demonstrably reduce manual triage time.
Architect data pipelines that integrate AI-powered extraction with deterministic business logic, ensuring reliability and explainability while accelerating time-to-value for new client deployments.
Drive technical decisions around system modularity, API design, and multi-tenant configuration strategies that support diverse client needs without creating unmaintainable complexity or slowing iteration speed.
Collaborate with AI teams to identify where machine learning adds genuine value versus where traditional logic performs better, optimising for both accuracy and client trust in production environments.
Establish patterns and architectural standards for a strategically critical product area, raising engineering quality while maintaining the velocity needed to respond to market demands and competitive pressures.
What You Need To Be Successful
Built and scaled production backend systems on the JVM (Java, Kotlin, or similar) that handled complex data processing or workflow orchestration, delivering measurable improvements in throughput, latency, or system reliability.
Designed architectures for systems that ingested unstructured or semi-structured inputs and transformed them into structured outputs, demonstrating strong judgement around data validation, error handling, and pipeline resilience.
Worked closely with product teams or clients to shape technical solutions based on real-world workflows, translating user needs into engineering decisions that balanced delivery speed with long-term maintainability.
Delivered features in ambiguous problem spaces where requirements evolved rapidly, showing ownership over outcomes rather than simply executing pre-defined tickets or specifications.
Made pragmatic trade-offs between technical excellence and time-to-market, shipping solutions that were good enough to validate hypotheses while maintaining the quality standards needed for production reliability.
Collaborated with cross-functional teams (product, design, AI, or customer success) to drive alignment around technical direction, demonstrating strong communication skills and an ability to influence without formal authority.

Quality Engineer - AI Enablement
Senior
Hybrid
Warsaw, Poland
🏢 Summary: Technical Quality Engineering role focused on building and scaling AI-powered test automation and quality self-service systems across engineering teams. The position centers on developing AI-driven E2E testing tools, automated failure analysis, and scalable release quality standards to enable engineers to own quality independently. It combines hands-on test automation, AI tooling development, and cross-team technical enablement in a rapidly evolving environment. 🗂️ Requirements: Experience building AI-powered tools or automations in production environments, Experience designing and implementing automated test strategies across unit, integration, and E2E levels, Hands-on experience with end-to-end test automation using Python and Playwright or equivalent, Ability to design and maintain scalable, reliable automated test frameworks, Experience integrating automation and analysis tools into CI pipelines, Experience coaching engineers on testing practices and improving team-owned quality, Ability to operate effectively in ambiguous, fast-changing environments 📃 Skills: Python, Playwright, AI, LLM, RAG, CI, Automation, Testing, E2E, UnitTesting, IntegrationTesting 🏢 Description: Location: Hybrid 2 days per week, based in Warsaw (Czackiego 15/17). We're open to candidates based outside Warsaw, provided the 2-day commitment is realistically sustainable from where you live. Please don't treat this as a starting point for negotiation - we value the structure and consistency it brings and we want you to see the value in it too. If you're based further away, we'll assume openness to relocation is part of the conversation. About hyperexponential (hx) At hyperexponential, we're building the AI-powered platform that enables the world's most critical decisions in a $7 trillion industry, which risks to take, and how to price them.

Surrounded by peers who stretch you, you'll do the best, hardest work of your life in a company engineered to endure. If that sounds like you, join us in building what comes next. About the team Quality Engineering at hx is undergoing a strategic shift. We're moving from an embedded model, where QEs sit in product teams and deliver hands-on testing, to an enablement model, where a small central team builds the tools, standards, and coaching that help every engineer own quality. It's one of hx's boldest engineering experiments: making quality genuinely self-service without sacrificing the rigour our customers rely on. The team sits at the intersection of test automation, AI tooling, release readiness, and organisational change. We're building AI-powered systems that make end-to-end test creation accessible to all engineers, automate failure classification and routing, and provide the standards, guidance, and feedback loops teams need to make better quality decisions independently. That means shaping quality strategy, improving release risk assessment, and establishing lightweight, scalable processes for staging, deployment, and learning from failure. This is strategic work with company-wide impact, requiring technical depth, strong technical judgement, coaching capability, and comfort with ambiguity. As the third member of this newly formed team, you'll join at a pivotal moment. You'll contribute to the managed transition away from embedded QE support, take ownership of AI-powered automation tools still being defined, and build the foundations that allow hx to scale quality across dozens of engineering teams. Your work will shape whether teams can ship independently, whether release processes stay fast and trusted as we grow, and whether hx can maintain velocity without compromising reliability. Check out our Engineering Candidate Hub for a behind the scenes look at the team you would be joining! What you'll be doing Accelerate the development and adoption of hx's AI-powered end-to-end test writing agent, improving its accuracy and framework coverage to the point where at least 15 engineers across 5+ teams are independently writing E2E tests within six months of widespread release. Design and deploy an AI-powered nightly build analyser that automatically classifies test failures and routes them to owning teams, reducing daily manual review effort by 80% and proving reliable enough to extend to the release pipeline. Establish quality self-service foundations for product teams by delivering test design guidance, executable E2E framework documentation (as AI agent specifications), quality standards references, and release risk assessment templates that enable at least three teams to complete release assessments without direct QE involvement. Support the managed withdrawal of QE support from embedded product teams by contributing to fixed-scope deliverables that ensure no critical gaps in E2E coverage or delivery confidence, enabling both current QEs to transition on schedule with no unplanned regressions. Grow E2E test coverage across the organisation through coaching, pairing, and AI tooling support, increasing the number of product teams writing their own E2E tests to at least 50% within the first 12 months. Build credibility and influence across engineering teams by working alongside engineers to solve real quality challenges, demonstrating the value of team-owned quality through concrete examples rather than process mandates, and making quality ownership feel like teams' own goal rather than an external requirement. What you'll need to have done Built AI-powered tools or automations in production environments (e.g., prompt engineering, agent design, RAG pipelines, or CI-integrated analysis), demonstrating the ability to design solutions others rely on rather than just using AI assistants as coding aids. Designed and implemented automated test strategies across multiple test levels (unit, integration, E2E) for complex systems, making sound judgements about what to test at which level and communicating those trade-offs clearly to non-specialist engineers. Owned end-to-end test automation using Python and Playwright (or equivalent frameworks), writing clean, maintainable tests with clear patterns that other engineers can extend, including experience managing flaky test suites and establishing conventions for new automation from scratch. Coached or enabled engineering teams to improve their testing practices through hands-on pairing and mentoring, demonstrating measurable improvements in team capability such as increased test coverage, reduced manual testing dependencies, or improved release confidence. Influenced quality improvements across teams you didn't directly manage, building credibility through practical demonstration and making benefits concrete rather than relying on process mandates or formal authority. Operated effectively in environments characterised by ambiguity and rapid change, taking ownership of problems from identification through to iterative solution, and adapting approach based on feedback without losing momentum. You're unlikely to thrive here if You prefer clearly defined processes and established playbooks over building the systems and standards from first principles in a rapidly evolving environment. You're more comfortable being the person who delivers quality work directly rather than enabling others to build that capability themselves, or you measure success primarily by your own output rather than what teams can achieve independently. You view AI tools with scepticism or aren't genuinely curious about how to apply them practically to solve real engineering problems, or you're unwilling to learn new languages and frameworks as the problem demands. If reading our Culture Document leaves you feeling neutral rather than energised, hx may not be the place where you'll do your best work. We're building something that asks for commitment and conviction, and we want you to feel excited by the opportunity to grow with us. Compensation At hx, we're committed to salary transparency.
