Senior Software Engineer II

Virta Health is on a mission to reverse metabolic disease in one billion people. Current treatment approaches aren’t working—over half of US adults have either type 2 diabetes or prediabetes, and obesity rates are at an all-time high. Virta is changing this by helping people reverse their metabolic condition through innovations in technology, personalized nutrition, and virtual care delivery reinvented from the ground up. We have raised over $350 million from top-tier investors, and partner with the largest health plans, employers, and government organizations to help their employees and members restore their health and take back their lives. Join us on our mission to reverse metabolic disease in one billion people. This role is a blend of real-world impact, technical challenge, and modern tooling. You’ll help build and evolve Virta’s data engagement platform — the system that turns partner and internally derived data into eligibility decisions and campaign-ready member audiences. You’ll anchor the engineering behind Member Marketing, which ensures the right members hear about Virta at the right time, and the Coverage Eligibility data it depends on, which determines whether someone can access life-changing care. You’ll create a trusted, observable path from raw data to member outreach: making identity, deployment context, data freshness, and transformation behavior explainable; designing safe recovery and replay mechanisms; and building reusable data capabilities that replace one-off operational workflows. You’ll modernize file- and API-based data exchange through explicit contracts, automated validation, observable workflows, and event-driven integrations where appropriate — reducing manual intervention without assuming every partner can adopt the same integration model. We work in an AI-augmented way. You’ll bring sound judgment about where AI-assisted tooling improves velocity, data-quality investigation, and operations — and where deterministic controls are required for correctness and safety. If you’re excited to own foundational data infrastructure, turn ambiguous growth requirements into durable technical contracts, and lead a squad solving hard data-correctness problems, this is a place where you can thrive. RESPONSIBILITIES - Design and own the data contracts and processing semantics that make identity, deployment context, eligibility, audience attributes, deduplication, and field persistence explicit and testable across the data lifecycle. - Build end-to-end observability and reconciliation that explains how source records become downstream outcomes — including data freshness, expected filtering, rejected records, deduplication, safe replay, and repair of historical state. - Lead technical discovery and delivery of high-impact work across Member Marketing and Coverage Eligibility, collaborating closely with Product, data, and external partners. - Partner with Product and Growth stakeholders to translate evolving audience and workflow requirements into reusable platform capabilities, keeping business policy cleanly separated from technical implementation. - Design for correctness and auditability in regulated workflows, including data provenance, consent and suppression controls, rollback, replay, and safeguards against incorrect or cross-customer data use. - Modernize legacy, file-based processes toward well-contracted, event-driven integrations with strong observability, resilience, and security. - Own systems end-to-end — from architecture through operations — driving improvements in reliability, partner experience, and long-term maintainability. - Apply an experiment mindset (Build-Measure-Learn) to validate assumptions and focus on outcomes over output, using AI-assisted tooling where it improves speed and quality without compromising correctness. 90 DAY PLAN Within your first 90 days at Virta, we expect you will do the following: FIRST 30 DAYS: LEARN & CONNECT - Understand Virta’s data ecosystem — architecture,…
