Senior Backend Software Engineer

The Role

Raydar is recruiting for this role on behalf of our client. Own backend and product delivery from early scoping through production in a small, highly autonomous engineering group. Make core technical choices and build intelligent, automated capabilities on top of large volumes of unstructured business data. Partner with company leadership to turn customer needs into dependable software.

What You'll Do

• Carry product features from initial problem definition through backend build and release.
• Design and deliver AI agent capabilities that perform dependably on large, untidy datasets.
• Decide on architecture, data modeling, APIs and tooling across the product.
• Raise and uphold the standard of engineering quality in the codebase.
• Drive demanding, high-impact initiatives independently with little supervision.
• Contribute to product direction together with the founders.
• Convert customer needs into technical solutions and support expanding client engagements.

What We're Looking For

• At least 5 years of backend engineering on products used directly by customers.
• Background at an early-stage startup or as a founder, with software running in production.
• A record of launching customer-facing backend services that operate at real production scale.
• Comfort leading technical approach when requirements are unclear and stakes are high.
• A generalist outlook: able to work across the whole product, not only infrastructure.
• Advanced Python skills applied to production services.
• Solid grounding in backend architecture and system design.
• Working knowledge of API design and relational databases.
• Practical exposure to building with large language models or agent-based AI.
• A product-minded approach that links engineering choices to customer and business results.
