Senior Backend Engineer

We're looking for an experienced Senior Backend Engineer to be a technical anchor across the team at our Ecosystem Company. You will operate with a high degree of autonomy while staying deeply embedded in collaborative engineering culture.

What you'll do

• Take ownership of complex backend systems from design through production — including architecture, implementation, and long-term maintenance
• Lead technical discussions, drive engineering decisions, and document trade-offs clearly for the team
• Mentor junior and mid-level engineers through code reviews, pairing sessions, and structured feedback
• Identify systemic weaknesses in our infrastructure, propose improvements, and execute on them with minimal direction
• Collaborate across engineering, product, and data to align technical direction with business goals
• Drive improvements to observability, reliability, and performance across our backend stack
• Contribute to hiring by participating in technical interviews and helping define the engineering bar

What you'll need

• 7+ years of backend engineering experience, with a track record of owning critical systems in production
• Deep expertise in Java (Spring Boot) and strong familiarity with Python; comfortable navigating a polyglot codebase
• Proven experience designing distributed systems — event-driven architecture, microservices, data pipelines
• Strong command of PostgreSQL and experience working with cloud-native infrastructure on AWS
• Someone who has been through hypergrowth or scale challenges and has the scars and instincts to show for it
• A multiplier: you make the engineers around you better through your presence, feedback, and technical clarity
• Comfortable operating in ambiguity — you can shape requirements, not just execute on them

What they offer

• Fulfil a role with entrepreneurial freedom and take a pre-validated business model to the next level
• Join an experienced founding team of serial and 2nd-time founders
• Attractive base and bonus compensation program
• Collaboration with top-tier investors and angels as well as leading market experts
