Note: The job is a remote job and is open to candidates in USA. Machinify is hiring a Senior/Staff Backend Engineer for its Right Payer Solutions team, joining either the Subrogation or Coordination of Benefits (COB) product line. The role sets backend technical direction and builds, operates, and improves scalable cloud-native services for payment-integrity decisions, while partnering with cross-functional teams and customers.

Responsibilities

• Set the architecture and technical direction for backend systems on your product line
• Ship cloud-native services that power accurate, high-stakes payment-integrity decisions
• Turn ambiguous product intent into concrete, well-sequenced backend design
• Own your services in production — reliability, observability, and performance at scale
• Raise the engineering bar and grow the team's programming maturity as we scale Rust
• Set the standard for AI-driven delivery, keeping delivery fast and under human oversight
• Simplify labor-intensive workflows by applying ML techniques to large volumes of data
• Balance new customer value with technical-debt cleanup to keep the product sustainable
• Partner with PM, ML/DS, QA and UX to shape product direction and outcomes
• Mentor engineers and act as the backend voice in cross-team planning
• Work directly with customers on systems that impact millions of lives

Skills

• 10+ years of backend engineering for Staff, 6+ years for Senior (full-stack experience a plus)
• Strong application design and system architecture across complex backend systems
• Proven ability to author technical design documents that satisfy engineers and product partners alike
• Substantial production experience in Rust, Java, Go, or Scala
• Proven experience designing, building, and operating distributed systems at scale
• Hands-on with containers and orchestration (Docker, Kubernetes) in production
• Ownership of CI/CD pipelines for your own services — building them, not just consuming them
• Production experience on at least one major cloud — AWS, GCP, or Azure
• Strong SQL and relational database skills; comfort across NoSQL and caching layers
• Hands-on experience with agentic engineering tools and workflows in production
• Proven ability to read complex code and own and continually improve code quality
• Strong cross-functional collaboration with engineering, PM, ML/DS, and leadership
• A pragmatic default and strong systems instinct — you find root causes, not symptoms
• Comfort with complexity and curiosity to define the path forward, not wait for one
• BS or MS in Computer Science, or equivalent experience
• Rust highly desired
• Technical leadership on Rust best practices — idioms, safety, and performance — as the team scales adoption across greenfield projects
• Healthcare, payer, or insurance domain experience; claims or payment-integrity workflows
• Experience shipping ML/AI-driven features in production and earning the business's trust in them
