## Description

About the company

Our client is a fast-growing software company.

The role

Raydar is recruiting for this role on behalf of our client. Design, build and run backend modules for a software platform, taking responsibility from early scoping through release and production support. Work alongside engineering and customer-facing colleagues to turn bespoke solutions into reusable products, including automated AI-driven workflows.

What you'll do

\- Design and build backend platform modules that support business operations at scale.

\- Take charge of a product area across its full lifecycle, with attention to reliability, security and low error rates.

\- Collaborate with deployed engineers, customer success and technical leadership to generalize one-off solutions into reusable products.

\- Develop and operate AI agents in production, adding testing, safeguards, monitoring and feedback mechanisms.

\- Lead infrastructure initiatives from planning to rollout, such as internal tooling that lets non-technical colleagues set up custom modules.

\- Shape data structures, processing pipelines and connections to third-party systems, including those that lack APIs.

\- Handle on-call rotation and root-cause investigations for the systems you build.

## Requirements

What we're looking for

\- At least 4 years of backend or systems engineering experience, with 6 to 7 years ideal; full-stack is fine if backend-heavy.

\- Experience running reliable, scalable production systems.

\- A degree from a top engineering school or engineering experience at a high-caliber technology company.

\- A history of taking a service or module from concept to stable production use on your own.

\- Hands-on experience delivering LLM-based or agent-based features to production users, as an applied engineer rather than a model researcher.

\- Daily use of AI coding tools.

\- Comfort working independently in a fast-paced, in-person team.

\- Ability to work on-site 5 days a week.

Bonus points

\- Experience at a fast-growing startup.

\- Experience with Python or TypeScript.

\- Top engineering school background.
