Trust and autonomy are two essential qualities that drive our performance. We simply believe in the idea of ​​“measuring outcomes, not hours”. Join us & see for yourself! About the role Project Support Team Project scope Provide first-class technical support for all IntelliJ Platform-based IDEs and their agentic developer tooling – both in-IDE plugins and standalone command-line agents that integrate with the IDEs over agent protocols. The team handles and investigates requests arriving through the web support portal, in-product feedback, social media, community forums, and marketplace reviews. Typical work includes: – Analysing performance, indexing, file-system, and networking issues. – Reading IDE logs, thread dumps, and CPU / memory snapshots to localise bugs. – Inspecting Java / Kotlin source code inside the IntelliJ Platform to understand execution flow. – Diagnosing issues across multiple delivery surfaces: IDE plugins, standalone command-line tooling, and integrations mediated by agent protocols. – Investigating authentication, licensing, and quota issues across vendor accounts, API tokens, and bring-your-own-key (BYOK) configurations for LLM providers. – Triaging YouTrack issues, escalating potential high-impact defects to development, and relaying user feedback to Product Management and QA. – Writing and maintaining KCS-compliant knowledge-base articles to scale answers across the team. Tech stack Java, Kotlin, Scala, IntelliJ Platform API, agent protocols (ACP, MCP), HTTP / REST APIs of LLM providers, Linux / Windows / macOS administration, TCP/IP, DNS, OSI networking, JVM diagnostic tooling (jstack, async-profiler, JFR, VisualVM), version control (Git), Docker, WSL, shell / Python / Node.js literacy Challenges – Deliver accurate root-cause analysis under SLAs across a product surface that spans CLI tooling, IDE plugins, and protocol-mediated in-IDE experiences — the same symptom often has very different causes depending on the surface. – Distinguish agent reasoning issues from infrastructure issues (provider quota, auth, networking, MCP server failures, IDE-side protocol transport bugs). – Balance deep code-level investigation with clear customer communication, including for non-technical users frustrated with agent behaviour. – Keep pace with a rapidly evolving AI/agent ecosystem: new LLM models, provider API changes, protocol updates, and frequent product direction shifts. – Coordinate with distributed development, IntelliJ Platform, and QA teams on urgent, high-visibility issues. – Improve team leverage: identify ticket patterns, write knowledge articles, and contribute to support-side automation and tooling. Team 2 people from VL, who are part of the 6-engineer team. Close cooperation with the other support team. What we expect in general: 3- 5  years of experience in support or QA roles is mandatory, Solid technical IT background spanning OS administration, networking (TCP/IP, DNS, HTTP, OSI), and software development. JVM languages preferred (Java, Kotlin, Scala); comfort with Python / Node.js / shell is a plus. Demonstrated ability to do root-cause analysis independently: read logs, JFR / CPU snapshots, thread dumps, and source code; reproduce issues end-to-end; isolate whether the problem lives in the CLI, the IDE plugin, the agent protocol layer, an MCP server, the LLM provider, or the customer’s environment. Experience troubleshooting LLM-based or agent-based products (e.g. Cursor, Copilot, Claude Code, or similar), or willingness and aptitude to ramp up quickly. Understanding of concepts like tool use, context window, prompt caching, BYOK, and quota systems. Familiarity with IntelliJ-based IDEs from a power-user perspective. Strong written communication: able to write replies that are short, direct, and helpful and internal bug reports that developers can act on without follow-up. Comfortable owning the end-to-end ticket lifecycle: triage, investigation, customer communication, YouTrack filing, follow-through, and KB authoring. Independent prioritisation across a noisy queue. Improving team leverage by writing KB articles, automating recurring workflows, and proposing process changes. Acting as a credible technical liaison to development and PM — relaying customer feedback so it actually shapes the product. Willingness to handle challenging customer conversations (refunds, license suspensions, frustrated power users) calmly and honestly.

🏢 Summary: Founding engineer role in a greenfield, AI-driven internal platform aimed at revolutionizing developer experience at scale through LLM-powered tools and agent-based systems. The position focuses on designing and integrating AI capabilities into daily development workflows across a large, globally distributed organization. You will collaborate internationally to build core infrastructure and intelligent automation supporting coding, testing, and deployment processes. 🗂️ Requirements: Hands-on experience building or integrating LLMs, AI agents, or coding assistants, Strong experience in Scala or another modern JVM language, Proven polyglot programming ability, Experience designing and implementing API integrations, Ability to build and maintain backend infrastructure, Fluent English for technical collaboration, Availability for collaboration with US West Coast time zone 📃 Skills: Python, TypeScript, Scala, Java, Kotlin, LLM, OpenAI, Anthropic, API, AWS, GRPC, MySQL, GitHub, Slack, Docker, Kubernetes, GCP, CI/CD 🏢 Description: We foster a dynamic culture rooted in strong engineering, a sense of ownership, and transparency, empowering our team. As part of the expanding VirtusLab Group, we offer a compelling environment for those seeking to make a substantial impact in the software industry within a forward-thinking organization. About the role You will be a founding member of a new, globally distributed team dedicated to a single mission: revolutionizing internal developer experience in a big technical organization (thousands of developers) via AI-based developer tools. Project scope You will be a founding member of a new, globally distributed team dedicated to a single mission: revolutionizing internal developer experience in a big technical organization (thousands of developers) via AI-based developer tools. Think of it as an internal startup, with the freedom to innovate and the stability of an established company. Our goal is to design and build an intelligent platform that assists developers at every stage, from coding and debugging to testing and deployment. Your team will be part of a larger 10-person group, with colleagues in California, Amsterdam, and Poland, organised into three focused sub-teams. This role requires collaboration (few meetings a week) with engineers on the US West Coast to ensure our platform meets the needs of our global team. What you will do Design and implement integrations with cutting-edge Large Language Models (LLMs) and APIs (like OpenAI’s models, Anthropic’s Claude, and more). Develop intelligent, agent-based systems to automate and assist in complex software development tasks. Engineer the core infrastructure for our AI agents, including components like MCP servers. Seamlessly weave AI capabilities into the daily workflows of our developers by integrating with essential tools like GitHub, Slack, IDEs, and client internal services, mostly Scala-based. Collaborate within a distributed, international team to research, prototype, and deploy solutions that have a direct impact on developer productivity and satisfaction. Tech stack This is a greenfield project, which means you’ll have a say in the technologies we choose. Nothing is set in stone. However, our environment and the problem space suggest we’ll be working with: Primary Languages: Python, TypeScript, Scala – based on available APIs and existing integration – but actual stack will be determined as the project progresses. The project will be based on internally developed services and solutions, utilising Scala, Java, AWS, GRPC, MySQL and more.
