Backend Engineer
About Themis
Themis is a collaborative governance, risk, and compliance platform helping banks, credit unions, and fintechs streamline oversight, strengthen compliance programs, and move faster with confidence.
Our customers operate in highly regulated environments where strong governance, risk management, and compliance practices are critical. We partner closely with financial institutions and fintechs to help them build scalable, effective oversight programs, strengthen third-party oversight, and navigate an increasingly complex regulatory landscape.
At Themis , we believe great companies are built through partnership, expertise, ownership, and execution. We’re looking for team members who are excited to solve meaningful problems, build trusted relationships, and help shape the future of governance, risk, and compliance.
About the Role
We’re looking for a Backend Engineer to help build and scale the secure, reliable systems that power the Themis governance, risk, and compliance platform.
In this role, you’ll work on a standard modern Rails stack, including Ruby on Rails, PostgreSQL, and Redis, building the APIs, services, background jobs, and data models behind our product. You’ll solve for the reliability, security, performance, and data integrity that financial institutions and fintechs depend on every day.
The ideal candidate has strong Rails experience, writes robust and well-tested code, thinks carefully about data and edge cases, and takes ownership of the systems they build. You understand that in a regulated domain, correctness, security, and reliability are not afterthoughts. They are part of the product.
Working Hours & Availability
Themis is a remote-first team. Engineering operates with flexible working hours and supports asynchronous work, but all engineers are expected to maintain meaningful daily overlap with our core collaboration hours of approximately 11:00 AM–4:00 PM ET for standups, pairing, code review, and time-sensitive work.
This role participates in a shared on-call rotation and may require availability outside of standard business hours to support production systems and respond to incidents. We aim to keep on-call sustainable through fair rotations and strong tooling.
We support flexibility where possible, but regular or extended blocks of unavailable time during core hours should be discussed and aligned in advance.
