Senior Software Engineer

About the role

We are seeking a Senior Software Engineer to join our dynamic team. This role requires a deep understanding of backend systems, APIs, and product workflows, with the ability to tackle complex problems from discovery through production.

Responsibilities

• Design and build reliable services, APIs, and product-facing workflows
• Work across backend systems, UI surfaces, event processing, and third-party integrations
• Turn unclear problems into concrete technical plans
• Own production behavior, including monitoring, alerting, logging, debugging, and runbooks
• Work with product, design, infrastructure, support, and other engineering teams
• Improve quality through tests, code review, observability, and simpler designs
• Use data and production evidence to validate decisions
• Take ownership of incidents and production issues when systems do not behave as expected

Requirements

• 5+ years of software engineering experience, with strong backend skills in Java, Scala, Kotlin, Go, or a similar language
• Experience owning ambiguous technical work and solving problems across multiple layers of a system, from backend services to product-facing frontend workflows when needed
• Comfortable with distributed systems, event-driven flows, caching, retries, rate limits, and the many ways production systems fail
• Experience building APIs, services, and integrations, backed by solid SQL and data-driven product decisions
• Experience with a cloud platform (GCP, AWS, or similar) and event systems like Kafka, RabbitMQ, or Pub/Sub
• Write automated tests, review code thoughtfully, and use logs, metrics, dashboards, and tracing to understand how your systems actually behave in production
• Strong production debugger who stays calm and clear during incidents, and can explain trade-offs to both engineers and non-engineers
• A bias toward simple, reliable solutions that other engineers can operate without you in the room
• Takes ownership of outcomes, not just tickets — asks what problem you're solving before jumping to implementation, validates risky assumptions early, and escalates when risk or scope is unclear

Qualifications

• Preferred minimum Bachelor's degree in CS, EE, SW, CE, MIS; or equivalent experience

Skills

• React/TypeScript or similar frontend experience (nice to have)
• Merchant- or customer-facing product work (nice to have)
• Third-party integrations (OAuth, account linking, external APIs) (nice to have)
• Redis/caching/queues at scale (nice to have)
• Experience with analytics and event data products (nice to have)
