About The Position

Welcome to the Agentic Commerce Era At Commerce, our mission is to empower businesses to innovate, grow, and thrive with our open, AI-driven commerce ecosystem. As the parent company of BigCommerce , Feedonomics , and Makeswift , we connect the tools and systems that power growth, enabling businesses to unlock the full potential of their data, deliver seamless and personalized experiences across every channel, and adapt swiftly to an ever-changing market. We believe in harnessing AI responsibly to unlock new possibilities, and we’re looking for individuals who use it intentionally to solve problems, accelerate outcomes, and expand what’s possible in their role. Our purpose is to help businesses confidently solve complex commerce challenges so they can build smarter, adapt faster, and grow on their own terms. If you want to be part of a team of bold builders, sharp thinkers, and technical trailblazers who shape the future of commerce, this is the place for you. We are looking for a Senior Software Engineer who can own complex problems from discovery through production. This role is not narrowly frontend, backend, or data engineering. The right person can work across services, APIs, event flows, product experience, production debugging, and cross-team delivery. They should be comfortable taking an unclear business or customer problem, breaking it down, making trade-offs clear, and shipping a reliable solution. We are looking for someone who raises the engineering bar without needing a lot of direction.

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 can solve 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
Worked 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 you can explain trade-offs to both engineers and non-engineers
Bias toward simple, reliable solutions that other engineers can operate without you in the room
Take ownership of outcomes, not just tickets — you ask what problem you're solving before jumping to implementation, validate risky assumptions early, and escalate when risk or scope is unclear
Don't take shortcuts around process, security, or production safety

Nice To Haves

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

Responsibilities

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.
