Senior Backend Engineer (Go)

We’re looking for a Senior Backend Engineer to help build the core infrastructure behind a high-stakes financial platform. This role sits at the heart of transaction processing, ledger correctness, and system reliability — where mistakes are costly and precision matters.

This is a hands-on, high-ownership role for engineers who care deeply about correctness, reliability, and long-term system design. You’ll work closely with mobile, infrastructure, and product teams to ship backend systems that power real financial workflows used daily.

What You’ll Do

 

• Build and scale production-grade backend services using Go
• Design and own financial ledger, accounting, and transaction systems
• Develop REST APIs powering mobile and platform features
• Implement real-time event and webhook processors with strict reliability guarantees
• Design and optimize PostgreSQL schemas for correctness and performance
• Integrate external financial services and infrastructure providers
• Own production reliability — observability, alerting, and incident response
• Make architectural decisions balancing performance, reliability, and long-term maintainability
• Ship production-ready systems and continuously improve backend stability

What We’re Looking For

 

• 5+ years of experience building backend systems
• 3+ years of production experience using Go
• Strong experience designing and building REST APIs
• Deep understanding of PostgreSQL and relational databases
• Experience building financial systems, payment platforms, or high-precision data systems
• Strong understanding of distributed systems and data consistency
• Experience operating production systems under load
• A track record of shipping and maintaining real-world backend infrastructure

Nice to Have

 

• Experience implementing double-entry bookkeeping or ledger systems
• Background in fintech, payments, or regulated environments
• Familiarity with event-driven architecture, CQRS, or event sourcing
• Experience with Google Cloud Platform
• Experience designing high-throughput, low-latency systems
• Familiarity with blockchain systems such as Solana or EVM-based chains

Why Join

 

• Work on mission-critical backend infrastructure
• High ownership over core financial systems
• Small team with meaningful technical influence
• Strong engineering culture focused on correctness and reliability
• Opportunity to build systems that users depend on daily
