At JetBrains, code is our passion. Ever since we started, back in 2000, we've been striving to make the strongest, most effective developer tools on earth. Today, AI-powered coding agents are becoming a core part of how developers write Kotlin – and we want to make sure they write it well.

The Kotlin AI Value Stream team is responsible for how AI agents understand, generate, and improve Kotlin code across all platforms: Android, Kotlin Multiplatform, server-side, web, desktop, and others. We build the evaluation infrastructure, error analysis tools, and post-training pipelines that measure and improve agent behavior on real Kotlin developer tasks.

As a Research Engineer on this team, you'll own the end-to-end loop: Analyze how agents fail on Kotlin → build evals that capture those failures → research and implement methods to fix them → measure the improvement. Your work will directly shape how millions of developers experience Kotlin through AI coding agents.

As part of our team, you will:

Build tools for agentic error analysis

• Design and implement tooling to systematically capture, classify, and analyse errors that AI coding agents make when generating Kotlin code.
• Build observability pipelines over agentic traces – mining patterns from agent sessions in JetBrains IDEs, Junie, Claude Code, Cursor, and other coding agents.

Build evaluation pipelines

• Design, implement, and maintain evaluation pipelines that measure Kotlin code generation quality across dimensions, including correctness, idiomaticity, build success, framework usage, and test coverage.
• Build simulation environments where coding agents can be measured on realistic Kotlin developer tasks – from greenfield KMP projects and Gradle dependency management to migrating Spring applications from Java to Kotlin.
• Own evaluation infrastructure: metrics, experiment tracking, automated regression checks, and reproducible benchmarking.

Research methods for improving agent and model behavior on Kotlin

• Experiment with post-training techniques (SFT, DPO, GRPO) to improve how models handle Kotlin-specific patterns, idioms, and frameworks.
• Investigate context engineering approaches: CLAUDE.md/AGENTS.md files, compiler-as-verifier feedback loops, Kotlin LSP integration, and MCP-based tooling.
• Run experiments to measure impact: A/B comparisons, benchmark suites, and before/after analyses on real codebases.
• Collaborate with model providers (Anthropic, OpenAI, and Google) to translate Kotlin-specific findings into model improvements.

Build public Kotlin benchmarks

• Design and build open-source benchmarks that measure AI coding agent performance on Kotlin tasks and eventually become the standard reference for the ecosystem.
• Create task datasets covering the breadth of Kotlin usage: the server side (Spring, Ktor), multiplatform projects (KMP), build systems (Gradle), Android, library development, and others.
• Include both mined real-world tasks and carefully designed synthetic tasks that test specific Kotlin capabilities.
• Maintain and evolve benchmarks as models improve, ensuring they remain challenging, relevant, and contamination-resistant.

We'll be happy to have you on board if you have:

• Hands-on experience building evaluation or analysis pipelines for LLMs or AI coding agents in a research or production setting.
• Strong Python engineering skills (at least three years), with the ability to write clean, maintainable code in data-heavy and ML-adjacent codebases.
• Experience with data analysis at scale: querying large datasets (SQL/Athena), building data pipelines, and performing statistical analysis of experimental results.
• The ability to own projects end to end – from identifying a problem in agent traces to designing an eval, running experiments, and shipping a fix.
• A product-aware mindset: You care about how agents are actually used by developers and can translate real failure modes into evaluation and training work.
• Familiarity with Kotlin or a strong willingness to develop deep Kotlin expertise (you'll be living in Kotlin codebases daily).

Our ideal candidate would also have experience with:

• Post-training LLMs: SFT, RLHF, DPO, GRPO – either hands-on training or designing the data and reward pipelines that feed into training.
• Modern deep learning frameworks (PyTorch) and LLM training stacks (TRL, verl, Megatron, or similar).
• AI agent development: tool-using agents, multi-step coding workflows, agentic frameworks.
• Evaluation frameworks and tools: Inspect AI, Promptfoo, LM-evaluation-harness, or custom eval pipelines.
• Experiment tracking and observability: Weights & Biases, MLflow, Langfuse, or similar.
• The Kotlin ecosystem: Android, Gradle, KMP, Spring, Ktor – with an understanding of the developer workflows that agents need to support.
• Contributing to or maintaining open-source projects, especially benchmarks or evaluation tools.

Don't check every box? That's okay – if you're excited about this work and bring strong fundamentals, we'd love to hear from you. We're happy to talk and provide the training you need to grow into the role.

Why join JetBrains? 

• Strong base salary. We offer competitive pay that reflects your skills and experience.
• Flexible work location. Enjoy the freedom to work from home or from the office.
• Remote work. Spend up to 30 days per year working remotely from abroad.
• Extra time off. More days to relax, recharge, and do the things you love.

As we continue to build and scale our engineering presence in Belgrade, we’re looking for a Senior Quality Engineer to join our Data and Integration Infrastructure team to help shape the platforms and systems that power our products globally.

About the Team

You will join an established engineering team responsible for enabling and accelerating product and service teams working on Kick. The team builds and maintains shared platform capabilities that underpin Kick’s core systems, improving reliability, consistency, and developer experience across the platform.

The team owns foundational components such as event pipelines, schema governance, service gateways, and notification delivery. These systems ensure that Kick’s services communicate reliably and that data flows across the platform are accurate, observable, and analytics-ready.

By providing robust, well-designed platform primitives and templates, the team plays a critical role in shaping how Kick is built and scaled, optimising ways of working, reducing duplication across teams, and forming the backbone for reliable integrations and data-driven decision-making.

Who We’re Looking For

We are looking for an experienced Senior Quality Engineer to help ensure the reliability, scalability, and safety of Kick’s core platform systems. In this role, you will work closely with engineers to embed quality throughout the development lifecycle, ensuring that platform components such as event pipelines, service gateways, and shared services are robust, testable, and safe for teams across Kick to build upon.

If you are passionate about improving system reliability, enabling fast and confident software delivery, and working in a collaborative, high-impact engineering environment, this role offers the opportunity to shape how quality is built into the foundations of the Kick platform.

Key Responsibilities:

• Embed quality practices within Agile product teams, and help implement the broader QA strategy across the SDLC.
• Collaborate closely with developers, product managers, and designers to define acceptance criteria, refine testability, and ensure a shared understanding of quality goals.
• Participate in code reviews and technical design discussions, providing input on testability, risk, and quality impact early in the development process.
• Identify testing risks and define appropriate testing strategies for complex features and releases.
• Promote testing best practices and support engineers in building high-quality automated and maintainable tests.
• Contribute to and extend existing automation frameworks while developing robust automated tests.
• Maintain and improve the team’s test infrastructure and tooling, ensuring efficient and maintainable test pipelines that support continuous integration and frequent deployments.
• Lead and perform exploratory testing of new and high-risk features, identifying edge cases and critical defects that automation may miss.
• Evaluate and adopt new testing tools and methodologies, contributing improvements back to the wider QA team.

Qualifications and skills:

• 5+ years of hands-on experience in Software Quality Engineering, with a proven track record of delivering high-quality software in Agile environments.
• Strong understanding of software quality principles, best practices, and testing methodologies (functional, regression, exploratory, and risk-based testing).
• Proficient in designing, developing, and maintaining automated E2E test suites using Playwright (preferred) or similar modern browser automation frameworks.
• Experience building and maintaining API test suites in Go, leveraging Go standard libraries to validate functionality, contracts, reliability, and error handling.
• Exposure to, or experience contributing to, lower-level tests such as Unit and Integration tests, with an understanding of the test pyramid and pragmatic trade-offs.
• SQL proficiency for investigation and debugging (e.g., exploring data, validating assumptions, and tracing issues in database-backed systems).
• Familiarity with Docker and Kubernetes (k8s), and cloud services (e.g., AWS, Google Cloud) to effectively test, validate, and troubleshoot modern deployments.
• Experience with CI/CD tools (e.g., AWS CodePipeline, GitHub Actions) to automate test execution and deployment workflows and ensure fast feedback.
• Experience using monitoring and logging tools (e.g., Datadog, New Relic, Grafana) to analyse system performance, detect regressions, and validate production readiness.
• Excellent problem-solving skills with a focus on preventing defects and improving reliability, not just finding bugs.
• Excellent communication and collaboration skills to work effectively with cross-functional teams.

Preferred Qualifications

• Familiarity with event-driven architectures and messaging systems such as Kafka and AWS SQS (or equivalent), including testing asynchronous workflows and eventual consistency.
• Strong knowledge of distributed and concurrent systems, including practical understanding of transactions, consistency trade-offs, and race-condition risks in production systems.
• Exposure to performance testing tools such as k6 (or similar), with the ability to analyse performance metrics, identify bottlenecks, and drive measurable improvements.

Why Join Easygo?

• Performance Reward: Annual bonus linked to individual and company performance.
• Professional Growth: Opportunities for development, learning, and career progression within a global organization.
• Health & Wellbeing: Private health insurance for you and your dependants.
• Office Perks: Daily catered lunch, snacks and beverages, parking reimbursement, and a modern Belgrade office.
• Global Exposure: Opportunities to collaborate with—and occasionally visit—our Melbourne headquarters.
