Senior Product Engineer (Fullstack, Backend Heavy)

The role

We're looking for a backend-heavy senior engineer who isn't afraid to touch the full stack. Your primary domain is our Golang services and distributed architecture, but you're a product engineer at heart — you understand the why behind the code and can jump into the React/Next.js frontend whenever that's the shortest path to delivering value. You'll join a lean tech team of fewer than 15 people, on systems that move around $1M in payouts every month.

What you'll do

• Design and ship Golang services inside a high-performance distributed system.
• Move from system design to production-ready code — clean code, test coverage, and documentation included.
• Contribute to the React/Next.js frontend when that's the fastest way to deliver.
• Work on payment infrastructure that handles around $1M in monthly payouts.
• Build event-driven flows and real-time data processing.
• Mentor other engineers and raise the engineering bar as the team grows.

What we're looking for

• 5+ years of backend experience, including at least 3 years of mastery in Golang.
• Comfortable with high-performance distributed systems.
• The skills to navigate and contribute to a React/Next.js frontend.
• Deep knowledge of PostgreSQL and Redis, ideally GCP.
• Architectural mindset — you move seamlessly from system design to shipped code.
• High-bandwidth communicator who mentors others and leaves ego at the door.
• Bonus: payment systems, event-driven architectures, or real-time data processing.
