Senior Engineering Manager TOKYO · JP

Juliusz
Fedyk

I build frontend teams — and the people in them. Deeply technical, relentlessly human. I once turned a group of juniors into 17 specialists; mostly I build tools that make invisible systems legible.

A people manager who ships.

I lead frontend teams — and grow the people in them. Deeply technical, but the work I'm proudest of isn't code: it's the engineers who outgrew the roles I hired them for.

Ten-plus years across frontend and creative tech — Dublin innovation labs, a Tokyo product team, a studio I co-founded back in Poznań. Somewhere along the way I figured out that the highest-leverage thing I do is turn a room of juniors into specialists who lead.

I'm a certified Design Thinking Facilitator who's just as happy in a TypeScript diff as in a 1:1. I like legible systems — for codebases and for careers — which is why I keep building tools that make invisible things visible.

Currently in Tokyo. Open to leading a frontend org that wants to grow its people, not just its headcount.

Teams I've built.

Thirteen roles going back to 2005 — here are the ones that shaped how I lead. The rest is on LinkedIn.

  1. Peatix

    2022 — 2026

    Senior Engineering Manager · Frontend · Tokyo

    Led the frontend team through a migration to modern frameworks. Coached juniors to mid-level and turned a codebase only one person understood into something new joiners could lead an epic in.

  2. Performance Media

    2020 — 2022

    Creative Frontend Team Lead · Poland

    Couldn’t hire seniors fast enough, so I built them. Hired for attitude below junior and trained to delivery fast — a gamified competency system took 5 people to 17 specialists across three teams in under two years.

Let's build a team worth leading.

Hiring for a frontend org that wants to grow its people? Want to talk products, or just terminal aesthetics? The prompt's open.
