As a Senior Backend Engineer on Coder's Enterprise Experience team, you'll build the systems that help large organizations run Coder in production with confidence. You'll improve how Coder scales, how it's upgraded, and how reliably it performs in regulated, air-gapped, and enterprise environments.
You'll work on a genuinely cross-functional team of backend, platform, and QA engineers who own the end-to-end experience for Coder operators. From designing new features to evolving Coder's architecture, you'll partner across engineering and product to solve complex problems and ship software that operators trust.
Design and build new features end to end, from technical design through production rollout.
Design and implement backend architecture changes that support Coder's long-term scalability goals.
Investigate and resolve scalability bottlenecks under production-like load, from database access patterns to concurrency handling in coderd.
Improve database migration safety and upgrade reliability through schema compatibility, background migrations, and safe rollback strategies.
Own the backend side of issues surfaced by Coder operators and administrators.
Document the design, implementation, and operational tradeoffs of the systems you build.
Participate in code reviews, RFC-style design discussions, and on-call rotations for the services you own.
5+ years of professional software engineering experience, including significant production experience with Go.
Deep understanding of Go's concurrency model, including goroutines, channels, the sync package, and debugging race conditions under real-world load.
Experience designing and operating relational databases in production, including schema design, migrations, and transactions.
Strong verbal and written communication skills.
Exceptional debugging and troubleshooting skills, with the persistence to drive complex problems to resolution.
A self-motivated, analytical engineer who enjoys tackling difficult technical challenges.

We believe that the interview process should be transparent, consistent, and enjoyable. We value your time and hope to complete the interview process in two to four weeks, if schedules allow. Through your interviews, you will meet a mix of individual contributors, managers, and senior leaders.
As an AI company, Coder embraces the use of AI tools, and we want to be transparent about our expectations as you navigate our interview process.
Not permitted: Using AI assistance during conversational interviews.
Permitted: Using AI tooling for take-home assessments. Please flag where and to what extent it was used in your take-home. Your submission will not be penalized for using AI as long as it is done honestly.
We use AI tools to help manage our recruitment process efficiently and fairly. Specifically:
Ashby helps us review inbound applications by surfacing candidates who best match the role requirements we've defined. This tool does not make hiring decisions; it helps our team prioritize which applications to review first.
Granola takes notes during our interview calls so our team can focus on the conversation with you.
All hiring decisions are made by humans. Our team reviews applications, conducts interviews, and makes final selections. AI tools assist us but never replace human judgment, and these practices are conducted in compliance with applicable data protection, AI governance, and labor laws. Your data is not used to train AI models.
In accordance with New York City Local Law 144, an independent bias audit has been conducted on "Automated Employment Decision Tools"; results are available for Ashby.
