Senior Full-stack Engineer (TS & Java/Kotlin) – AI Developer Tools

🛠️ What You’re Getting Into

We’re building AI coding agents that actually help developers — not autocomplete party tricks, but real tools that understand your project, refactor your code, generate unit tests, and scaffold entire repos. The kind of tool we wish existed every time we hit a deadline with 400 TODOs left.

We’re looking for a senior engineer who’s confident in TypeScript, curious about how things work under the hood, and unfazed by weird tech or fast-changing specs. If you’ve ever said “eh, I’ll figure it out” and then actually did, you’re the type we want. Sometimes that means jumping into Java or Kotlin to tweak our JetBrains IDE plugin (with a bit of Swing). If that sounds more fun than scary, you’ll fit right in.

We’re still early, so:

• The problems are big.
• The codebase is (mostly) clean.
• The opportunities to make your mark are everywhere.

We’re led by Andrew Filev (Wrike founder) and backed to move fast and build real stuff. You’ll join a small, sharp team where every line of code matters.

🔍 What You’ll Do

• Build the core functionality of our AI coding agent — from intelligent code edits to repo-wide refactors, project scaffolding, and beyond.
• Write excellent TypeScript and make decisions that scale, but also get your hands dirty across the stack when needed.
• Contribute to our Python-based AI integration layer and model-serving infrastructure. Even if you’re learning on the fly.
• Dive into unfamiliar tech, frameworks, and tooling. We’re not hiring domain-specific robots — we want adaptable humans (or incredibly convincing simulations).
• Collaborate with a team that actually ships. No 14-person alignment meetings. Just smart people building cool stuff.

🧠 What You Bring

• 10+ years of real-world engineering experience, including deep experience with TypeScript (or a close cousin).
• Working knowledge of Java or Kotlin — enough to jump into JetBrains IDE plugin development when needed.
• Familiarity with Python (especially in the context of scripting, automation, or AI workflows) is a big plus.
• Generalist mindset — you’re comfortable picking up new languages, frameworks, and systems as the job demands.
• Strong CS fundamentals — data structures, algorithms, architecture.
• Experience building and maintaining complex production software (ideally with users!).
• Clear, low-drama communication. We don’t do ego battles or Slack novels.
• A low fear of failure and a high bias for action.

🧰 Tech Stack

• Frontend: TypeScript, VSCode Extension APIs, React, Java/Kotlin, Swing
• Backend: Node.js, Python, FastAPI

🚀 Why This Role?

• Massive Impact: AI is changing how software gets made. You’ll be building tools at the center of that shift.
• No Busywork: We cut out the noise so you can focus on solving interesting problems.
• Experienced Leadership: Andrew Filev scaled Wrike from nothing to a $2B exit — and he’s not here to waste time.
• High Talent Density: Senior team. No babysitting.
• Remote Friendly: We hire globally and care more about output than timezones.
• Ownership: Equity included — you’re not just an employee, you’re part of the upside.
