We expect you to have:

• A proven track record as an ML/AI Lead.
• At least five years of experience in ML/AI systems, with at least two years focused on LLMs and generative AI.
• A deep understanding of the LLM ecosystem, including model architectures and fine-tuning approaches.
• Hands-on experience with:
• Prompt engineering and LLM pipeline design, including evaluation.
• Agentic frameworks such as LangChain, LlamaIndex, LangSmith, smolagents, or an equivalent.
• Vector databases and retrieval-augmented generation (RAG) patterns.
• Deploying and scaling LLM-powered applications using APIs (e.g. OpenAI or Anthropic) or open-source models.
• Strong Python skills – Kotlin knowledge would be a plus.
• Excellent communication skills, with the ability to explain complex technical concepts to diverse audiences.
• Proficiency in English, both written and verbal. 

Our ideal candidate would have:

• Experience with ontologies, knowledge graphs, or graph-based reasoning.
• Experience in early-stage startups – you enjoy the zero-to-one phase.
• The ability to think strategically about product-led AI, beyond just training models in isolation.
• A background in code analysis, developer tools, or software engineering research.

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.

At JetBrains, we create tools that are supposed to make software development fun and productive. As is known, the top fun in the development process comes from authoring build files—a unique combination of guesswork and riddle solving. With Amper, we want to eliminate all that and create a build tool that just gets out of the way. 

Amper is the next-generation build tool for the JVM and the Kotlin ecosystem. It aims to make simple things easy while giving enough power to build tomorrow's Enterprise JVM applications. 

The first experimental version of Amper was released at the end of 2023. Since then, we have been constantly iterating based on user feedback and evolving the tool, and presented it at the KotlinConf 2024.

We’re looking for an Amper Project Lead to take full engineering ownership of Amper. You’ll connect the dots and create an experience from the IDE to the build configuration language to shape how JVM applications are built. Along with a stream of algorithmic puzzles, architectural design, integration with the underlying OSes, and toolchains. Whether you are an expert with an in-depth understanding of specific areas or a specialist with a broad knowledge of technical areas, you’ll find a good fit!

You’ll work closely with Engineering, Developer Advocacy, and Marketing to define the product’s value proposition, define the features, implement it, get first users, and scale up.

In this role, you will:

• Provide technical leadership of the Amper team
• Evaluate available options for design and implementation, and solve them with the team – from IDE starters to incremental compilation
• Create, test, and implement a go-to-market strategy for Amper

We’re looking for someone who:

• Have a strong technical background and at least 5 years of Java/Kotlin development experience
• Understand algorithms and data structures, and can apply them in your daily work.
• Has a strong understanding of build systems
• Has experience in hiring, people/team, and project management

We’d be especially thrilled if you have:

• Experience in developer tools, compilers, programming languages, emerging tech R&D teams, or startups
• Experience and track record in the open source community
• A history of working on advanced technologies.

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.
• Medical insurance allowance. Enjoy peace of mind for you and your family.
• Learning and development opportunities. Access to conferences, courses, and language classes.
• Language classes. Pick up the local language or sharpen your English skills.
• Fuel your day. Enjoy a hot meal or receive a lunch allowance on workdays.
• Mental health support. To help you feel your best, we provide easy access to professional mental health services.
• Sports benefit. Enjoy an on-site gym or sports club stipend.
• Internal events. Join company-wide celebrations and team gatherings.

At JetBrains, code is our passion. Since 2000, we’ve focused on helping developers work faster and with fewer distractions by automating routine checks and fixes.

Hexana is a project within JetBrains’ Innovation Hub. We’re building a reverse engineering and binary analysis toolkit that brings semantic understanding of compiled binaries into the IDE and AI-assisted disassembly workflows.

We started developing Hexana with WebAssembly and have already shipped an MVP with over 1,000 downloads and early adopters that include teams at Oracle and various others from within the Kotlin ecosystem. Now we’re expanding into the broader binary world: ELF, Mach-O, PE, APE, LLVM bytecode, and more. The goal is to define a new category inside the IDE ecosystem.

We’re now looking for a Product Manager to help move Hexana from early validation to a scalable, strategically positioned product by driving research, refining direction, and building the case for long-term impact.

This role could be a good fit if you:

• Want to shape a new category in developer tooling.
• Are genuinely interested in low-level systems, binaries, and reverse engineering.
• Enjoy working at the intersection of deep technical work and product strategy.
• Are comfortable working in a small, highly technical team.
  
  

In this role, you will:

• Conduct discovery interviews with system engineers, reverse engineers, compiler developers, and other advanced users to understand their workflows and needs at the binary layer.
• Translate technical capabilities and user pain points into a clear, defensible roadmap.
• Continuously validate hypotheses and refine positioning through research and competitive analysis.
• Track the reverse engineering and binary tooling landscape, including IDA Pro, Ghidra, Binary Ninja, and others, to inform strategy.
• Define and evolve the go-to-market and monetization approach.
• Communicate product progress, strategy, and results to JetBrains sponsors and internal stakeholders.

We’ll be happy to have you on our team if you:

• Have at least 5 years of experience in product management or a role with similar ownership and responsibility.
• Have experience building or scaling developer tools, IDE plugins, workflow platforms, or other technically demanding products.
• Have directly influenced the success of a technically complex product, not just built processes around it.
• Have a strong technical mindset and can earn the respect of engineers working on compilers, binary formats, and low-level systems.
• Are comfortable with ambiguity and enjoy turning exploration and research into clear product direction.

We’d be especially glad if you:

• Have worked in reverse engineering, compiler, security, or binary tooling.
• Have zero-to-one experience shaping an early product, validating hypotheses, and driving initial adoption.
• Care about making complex, low-level systems more elegant, accessible, and integrated into the developer experience.

Hexana is still in its early stages, but it is real. The team is small, technical, and ambitious. This is an opportunity to help define how binary intelligence becomes a natural part of the modern IDE ecosystem, backed by one of the most respected developer tools companies in the world.
