Senior Software Engineer

The role

Raydar is recruiting for this role on behalf of our client. Build backend-heavy services and AI agents for a software product, owning one functional area end to end and possibly leading a small group of engineers. The work spans model pipelines, infrastructure, backend services and user-facing features, with a strong focus on reliability and auditability. A background in backend or infrastructure engineering and prior experience shipping AI agents are central to the role.

What you'll do

• Own one functional area end to end, working with a small group of two to three engineers and possibly leading them.
• Build and run AI agents across the model pipeline, infrastructure, backend and user interface.
• Create verification, guardrails, monitoring and evaluation for non-deterministic AI systems so that users and reviewers can rely on them.
• Design the data context agents work from, and ingest, normalize and reconcile data from many third-party business systems.
• Build long-running, fault-tolerant workflows and idempotent, auditable writes to external systems of record.
• Spend time with end users to learn their processes before building the system that replaces the manual work.
• Contribute to full-stack work when the problem calls for it.

What we're looking for

• At least 5 years of experience, mostly in backend or infrastructure engineering.
• Experience building and shipping AI agents in any domain.
• Bachelor's degree in computer science or a closely related engineering field from a leading university; strong alternatives are considered for other degrees paired with comparable experience at a top technology company.
• Experience building demanding backend systems such as distributed pipelines, ledger or transactional systems, integration platforms or workflow engines.
• Authorized to work in the US and able to work on-site five days a week.
