Job description

The best senior engineers we've worked with share a specific trait: they make the engineers around them better — and they don't think of it as mentorship. It's just how they work.

If that description feels accurate to you, this might be your role.

At Wildlife's Live Games Tech team, you'll have real ownership over systems serving millions of daily active players. You'll lead architectural decisions — not abstract ones, but the kind that have immediate, measurable consequences in production. You'll define how the team operates in production. You'll develop the engineers around you, not as an add‑on responsibility, but as the natural output of how you approach technical work.

No approval gates slowing you down. No architectural decisions made by committee. The scope is real. The autonomy is real. And the impact is visible every day in the metrics and the product.

Our stack: Unity/C# on the client, Go on the backend, AWS and Kubernetes for infrastructure.

WHAT THIS LOOK LIKES DAY-TO-DAY

• Leading the design and implementation of complex features across mobile and backend — with sound, explicit architectural trade‑offs
• Owning technical decisions for your area: architecture, performance, scalability, and the accountability that comes with each
• Full production ownership post‑release: monitoring, reading signals, iterating fast
• Defining and evolving the team's observability practices: SLIs, alerting, dashboards, incident response
• Driving proactive codebase improvements — as a habit, not a project
• Developing engineers around you through code reviews, technical discussions, and pair programming — as a natural consequence of how you work
• Shaping feature direction alongside product and design from the first conversation

WHAT YOU'LL NEED

• Solid experience as a developer with production systems at scale
• Strong background in software architecture and system design
• Experience with monitoring, observability, and incident response in live systems
• A demonstrated ability to lead technical initiatives and raise the bar for those around you
• Working proficiency in English

WHAT WE'D LOVE TO SEE

• Unity/C# for mobile
• Go and Kubernetes‑based backends
• AWS
• A background in games or other high‑traffic consumer products

WHO YOU ARE

You've shipped things that live in production, and you know what real ownership feels like. You make architectural decisions with confidence and explain the why clearly — to engineers, product, and leadership. You think in systems. You don't need the perfect spec to start moving. And when something breaks in production, you're already thinking about the fix.
