They are looking for a Senior Engineer to join their product execution team. This is not a role for someone who only wants to write isolated features. This is a role for an expert individual contributor who takes Extreme Ownership over the core product surface—including the developer UI, backend services, CLI tools, and advanced execution agents that thousands of engineers rely on daily.

You will build and evolve their core developer platform end to end: from the React-based user interface and Node.js-based backends that stream complex agent execution steps, through state-machine agent frameworks, to robust authentication, billing, and system integrations that make the platform enterprise-ready.

You will collaborate closely with engineering and architecture teams to deliver an unparalleled developer experience.

Requirements

  • 8+ years of hard-core software engineering experience.
  • Proven track record as a Senior or Expert-level individual contributor.
  • Confidence owning complex product initiatives from initial design through to production.
  • Absolute expertise in TypeScript, Node.js, React, and Next.js.
  • Hands-on experience building with LLMs and AI agent architectures in real-world production environments.
  • Comfort working with containerized environments (Docker) and VM ecosystems for isolated, secure execution of generated code.
  • Deep understanding of monorepo structures such as Nx.
  • Familiarity with IDE extensions, custom CLIs, and third-party developer integrations.
  • Ability to elevate engineering teams through technical standards and architectural guidance.
  • Confidence collaborating hands-on in a shared office environment.
  • Strong understanding of business-driven engineering decisions and scalable system design.

What you can expect

  • Frontier Product: Building state-of-the-art systems and state-machine architectures that redefine how modern developers interact with AI workflows.
  • Elite Environment: Working alongside C-level executives, industry visionaries, and core platform architects with minimal bureaucracy.

Responsibilities

  • IDE Extensions & Backends: Build and optimize the IDE user interface layer and streaming backends that seamlessly connect developers to long-running coding agents.
  • State-Machine Agents: Develop, test, and improve automated AI workflows using a proprietary state-machine framework.
  • CLI Tooling: Create and maintain command-line utilities optimized for automated code generation, linting, and debugging.
  • User-Facing Platform Surface: Design and implement secure authentication flows, subscription management, and enterprise-grade VCS integrations.
  • Scale & Infrastructure Collaboration: Work with infrastructure engineers to deploy secure, containerized agent runner infrastructure to the cloud at scale.

Recruitment process

  • 1.5-hour pair programming session with the client’s core engineering team.
  • 1-hour technical interview with the Principal Engineer.
  • Optional additional 1-hour conversation to explore deeper fit or alternative skillsets.
  • Final decision and offer.

To środowisko, w którym liczy się samodzielność, jakość techniczna i umiejętność rozumienia całego systemu. • Jeśli szukasz spokojnego utrzymania prostych CRUDów, to prawdopodobnie nie będzie dobre miejsce. • Jeśli chcesz pracować nad platformą, w której po roku zdobędziesz doświadczenie większe niż w kilku typowych projektach enterprise, porozmawiajmy. ⚙️ Proces rekrutacyjny Krótkie spotkanie online, 25–30 minut Rozmowa o doświadczeniu, oczekiwaniach, dostępności i dopasowaniu do projektu, ustalenie warunków współpracy.
