About the company

Our client is a software company.

The role

Raydar is recruiting for this role on behalf of our client. Lead the delivery of a security-hardened deployment of an existing software platform inside a restricted public-sector cloud. The work is mostly backend engineering with some frontend, and involves close collaboration with machine learning and platform colleagues.

What you'll do

\- Re-create an existing application stack in a locked-down government cloud, prioritizing security, stability and reliability.

\- Design and implement data separation so each user can only view information appropriate to their authorization level.

\- Keep backend services dependable and expand infrastructure capacity as more users join.

\- Work alongside a machine learning engineer to migrate retrieval-based AI pipelines, benchmark models and bring down running costs.

\- Stay aligned with the wider platform engineers so new capabilities reach the government deployment.

\- Split your time roughly 70% backend and 30% frontend.

\- At least 1 year of hands-on work with systems hosted in a highly regulated defense or federal cloud environment.

\- Strong skills in React and Python, with a backend-leaning focus.

\- At least 1 year in a startup setting; a mix of large technology company and startup experience is fine.

\- Practical experience with AI services on a major cloud provider.

\- Background in machine learning, retrieval pipelines and large language models, ideally at significant organizational scale.

\- Bachelor's degree in computer science or a related STEM field.

\- Comfort leading client conversations and explaining technical ideas plainly to non-technical audiences.

\- Ability to work on-site five days a week.

Bonus points

\- Familiarity with federal security and compliance frameworks and the authorization process for government systems.
