- Design backend services and APIs connecting task authoring, data collection, evaluation, quality review, and training infrastructure.
- Collaborate with research, operations, and go-to-market teams to ship and improve systems as needs evolve.
WHAT WE'RE LOOKING FOR
- At least 3 years of experience building and shipping production software, with end-to-end ownership of user-facing or internal products.
- Proficiency in Python and a modern web stack such as React, TypeScript, or Next.js.
- Experience building backend services, APIs, and databases, plus hands-on cloud infrastructure, Docker, CI/CD, and production debugging.
- Experience creating dashboards, monitoring or observability interfaces, and tools for data inspection, review, or quality assessment.
- Background in data collection, labeling, annotation, evaluation platforms, developer tools, or partner-facing workflows is valuable.

About this listing
Published on Ashby under the board identifier Clera, which is the name the employer’s own job board carries. RoleSprint has not verified the company’s registered or trading name, so it is shown exactly as published rather than tidied up.
RoleSprint is not the employer and not a recruiter. Applications are made on the employer’s own site and never reach us; what RoleSprint does is help you decide whether a role is worth your time and prepare for it if it is.
