About The Position

The Senior Backend Engineer will co-own a Go API service backed by Postgres with the engineering lead and serve as the reviewer of record for billing, eligibility, partner integration, and member data changes. The role covers plan configuration, employer contributions, plan years, Stripe subscriptions, enrollment, and the process of turning employer eligibility files into active memberships. It also owns partner integrations, scheduled jobs, production health, HIPAA-related member data protection, and guardrails for agents working with billing, eligibility, and member data.

The company describes its development approach as AI-first, with agents involved in planning, building, reviewing, and testing; engineers focus on judgment, data correctness, review, and production decisions. The role has end-to-end ownership of projects, including planning, implementation, testing, and rollout, with an automation partner covering regression.
