JOIN YOUSICIAN

Yousician impacts and enriches the lives of millions of people by empowering them to play music they love, learn something new, and nourish their well-being. We merge music and tech to amplify the everyday. We reimagine the way people learn to play so that everyone can play. 

And, you don't need to be a musician to join Yousician!

We're a band of passionate professionals who love what they do, are great at it, and move to the beat of the same drum. We're for all players: from newbies to seasoned pros. If you are looking for a rewarding career opportunity that helps shape the future of music-tech, you're in the right place!

Make Musicality as Common as Literacy

At Yousician, we reimagine music education for a billion people. Our products, Yousician and GuitarTuna, are the world's leading music learning and tuning apps, used by millions of people to learn, play, and tune their instruments every day.

We believe subscription revenue is won in the details, not in the pitch deck. Paywall copy, trial lengths, price points, renewal offers, reactivation campaigns: each one is a craft, and each one moves the number when it is done right. We are hiring a Product Manager with strong monetization craft to run experimentation across both of our products

The Role

Your mission is clear: you help turn players into paying subscribers, and keep them, across Yousician and GuitarTuna.

You will run paywall, pricing, and offer experimentation end to end for both products. Hypothesis, brief, ship, readout, decision. You will maintain the live revenue forecast that ties every test back to the quarterly plan, and reconcile it monthly against what actually landed. Multiple tests run every week. Every one of them has a written brief and a clean readout.

This is a senior specialist role. You come in with a point of view on paywall mechanics, price point elasticity, trial length trade-offs, holdout discipline, and primary-metric selection. You will report to the Head of Revenue and work closely with them to translate monetization priorities into a concrete experimentation roadmap. You will work day to day with embedded engineers on both products, a test designer, and a data partner. You are a strong monetization specialist and a key thought partner on experimentation, pricing, paywalls, and offers.

What You'll Do

• Run the Experiment Cadence: Own the weekly operating rhythm for monetization experimentation across both products, including planning, launch readiness, readouts, and decision follow-through. Ensure each experiment has a clear hypothesis, success metric, guardrails, and decision rule before it goes live.
• Own the Test Portfolio Execution: Translate agreed monetization priorities into a concrete test roadmap across Yousician, GuitarTuna mobile, and the GuitarTuna web experience. Design variants, write briefs, specify subscription-platform configuration, and work with engineering on delivery.
• Maintain the Revenue View: Maintain the live monetization forecast and experiment-level revenue view, and help reconcile plan vs actual together with the Head of Revenue and Finance.
• Partner with Finance on Pricing: You build the case for every price change, walk Finance through the numbers, and manage the rollout across iOS, Android, and Web with the regional and store constraints that come with it.
• Keep the Scorecard Honest: Maintain the weekly Monetization Tracker and experiment readout cadence, ensuring that key metrics, forecasts, and decisions stay consistent and reliable. Partner with the Head of Revenue, Data, and Finance to investigate mismatches and keep the monetization view decision-ready.
  
  

Who You Are

• You bring strong monetization craft: You have shipped across the full spectrum: paywall copy, paywall placement, price points, trial variants, intro offers, winback campaigns. You know where the wins usually come from and where the traps are.
• You are resourceful and proactive: You do not wait for perfect conditions. You can spot practical opportunities, identify problems worth solving, and move things forward in an under-resourced or ambiguous setup. Whether through tooling, lightweight prototyping, or creative cross-functional problem solving, you know how to turn momentum into shipped work.
• You think in numbers: Baseline, uplift, volume, EUR. When you pitch a test, you already know what it is worth. When you kill one, you can explain why in one sentence.
• You have opinions on methodology: You have views on MDE-setting, holdout design, sample ratio mismatch, guardrail thresholds, and sequential testing. You can defend them and you update them when the data tells you to.
• You decide by the data: You have killed winning-looking tests when the stats did not support them, and you have shipped underwhelming-looking ones when the logic did. You do not fall in love with hypotheses.
• You understand the full system: Monetization decisions do not live in isolation. A price change can affect winbacks, a paywall test can change retention, and a trial decision can shift downstream value. You can think across the full subscriber lifecycle and make decisions with LTV in mind, not just immediate conversion.
• You communicate directly: You write briefs that engineers can build and readouts that Finance can trust. Conclusion first, numbers second, caveats third.

Requirements

• 5+ years in monetization, paywall, pricing, or subscription PM roles at a consumer subscription business. Mobile preferred, web acceptable.
• Shipped at least 30 paywall, pricing, or offer experiments you personally scoped, briefed, and read out.
• Fluency with experimentation platforms such as Eppo, Statsig, GrowthBook, Optimizely, or an in-house equivalent. You understand how metrics, guardrails, and variants are configured, and can work effectively with data and engineering to ensure experiments are set up correctly.
• Working knowledge of mobile subscription mechanics: trial lengths, intro offers, grace periods, renewal cycles, refund behaviour on iOS and Android.
• Strong analytical fluency with SQL familiarity. You are comfortable validating analysis, interrogating results, and partnering closely with analysts on experiment readouts. 
• Ideally, you have direct experience with RevenueCat, Adapty, Purchasely, or a comparable subscription platform.
• Excellent written and verbal English communication skills.
• Based in Berlin or Helsinki.

Why You'll Love Working Here

• Impact: Your work directly influences the P&L across two products with millions of users. The tests you ship translate into EUR every week. Few PM roles have such a short feedback loop.
• Ownership: You own the monetization experimentation engine and have direct influence on how monetization ideas are shaped, tested, and scaled. You work closely with the Head of Revenue to translate strategy into shipped outcomes.
• Culture: We are a band, not just a company. We have jam sessions in the office, great gear, and a team that cares about the mission.
• The Basics: Competitive salary, lunch benefits, culture vouchers, and a modern office in Helsinki and Berlin.

How to Apply

Please submit your CV and a brief cover letter describing the last paywall, pricing, or offer experiment you shipped. Tell us the hypothesis, the result, the decision you made, and what you would do differently next time.

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.
• Medical insurance allowance. Enjoy peace of mind for you and your family
