Lead Game Engineer

At Trailmix, our players are the very reason we exist and our mission is to create delightful spaces where millions of people can flourish. Our hit game Love & Pies, launched in September 2021, has resonated with millions worldwide and we build free-to-play mobile games that are snackable yet filled with heart, humour, and stories that stick. We’re a focused and highly collaborative team with a big creative spirit.

We believe the best games are made when the people behind them feel inspired, supported, and proud of the work they do.

That’s why our values sit at the heart of how we work, shaping every decision and creative choice we make.

• We win as one: Success is shared, and collaboration fuels everything we do because great games are never built solo.
• We are resilient by nature: We adapt and rise stronger each time because every challenge is a chance to evolve.
• We are powered by our players
  :
  Every choice begins with them because when our players thrive, so do we.
• We are kind and direct: We speak with honesty and care because clarity and compassion build the trust that makes us better.
• We stay curious and grow: We ask, explore, and learn because curiosity keeps our creativity alive.
• We decide boldly and own fully: We move with courage and conviction because great ideas only matter when we stand behind them.

Our values are what set Trailmix apart: they guide us in crafting games that are joyful, authentic, and player-first. We've created a workplace where both people and players feel seen, supported, and inspired. If you’re excited by meaningful creativity, true collaboration, and making games that bring people joy, you’ll feel right at home here, too.

The Opportunity

As Lead Game Engineer on a New Game Project, you will be accountable for the technical direction, delivery confidence, and people leadership of the engineering team building our next game. This role carries full hands-on engineering craft and extends into people management and delivery accountability.

As Lead Game Engineer, you will still write code often on the systems that carry live traffic; however, your primary impact comes from enabling others
, owning the technical approach
, and turning a game that works into one that keeps working at scale
.

You will have direct line-management responsibility for the engineering team and will be accountable for their performance, growth, and clarity of ownership. We are hiring for this role to build toward a sustainable Live Games team, meaning the architecture and standards you set now must hold as the game grows in players, content, and complexity, year after year.

The Day to Day

O
our New Games are being built to run for years, not to be proven and handed on. Your job is to get it live and keep it moving with a dependable release cadence, fast diagnosis when something breaks, and a codebase that can absorb continuous new content without seizing up. You optimise for sustainable velocity: shipping change into a running game without putting the player experience, the data, or the team at risk.

Technical Leadership & Architecture

• Own the game’s architecture and technical direction; make the major technical calls and bring the team in where it matters. You define which decisions you own, delegate, or take to the team - and you are accountable for the outcome, not for making every call alone.
• Match engineering investment to ris
  k - keep routine content, tuning and config changes cheap and fast to ship, and know when something touching live data, economy or player accounts warrants full production rigour.
• Uphold engineering standards
  , code quality, and performance; stay hands‑on in complex or high-impact work, often on the systems where a mistake reaches players fastest.
• Set the architecture and…
