Senior Software Engineer, Backend | Audit Product Team

Machinify is a healthcare intelligence company delivering AI-powered solutions that improve value, transparency, and efficiency across the healthcare payment continuum. The Senior Backend Engineer will set technical direction, design and build scalable backend systems for the Audit product team, apply machine learning to large-scale data, and guide the adoption of agentic engineering practices.

Responsibilities:

• Deepen your understanding of the healthcare claims and payments domain
• Developer Coach/Multiplier - An experienced Java, Scala and/or Rust developer who not only builds production-grade services, but also contributes to setting standards, mentors others, and elevates the team’s overall programming maturity
• Backend voice in cross-team planning and the glue in cross-functional execution
• Contribute to new product development of complex in-browser applications, taking advantage of your holistic view to ensure our application is extensible, scalable, and secure
• Balance customer-facing features and technical debt cleanup to keep the software suite sustainable
• Architect and implement complex applications that apply ML techniques to large volumes of data, simplifying labor-intensive processes through good user experience
• Design systems that work together to deliver a good-performing, reliable application
• Bring agentic engineering practices into the team’s day-to-day work and help the team adopt them effectively

Requirements:

• 8+ years of experience spread across backend programming (additional full-stack experienced highly desired)
• Proven experience designing and shipping customer-facing web application products, you've built features that serve external users and you're energized by that kind of work!
• Meaningful experience with Java or Scala
• Experience designing, building, and operating distributed systems that run reliably on cloud-services at scale (high throughput, high availability)
• The ability to write a Technical Design Document (TDD) that a staff peer trusts and a product lead can understand — turning ambiguous product intent into concrete backend design
• A product and user-driven mindset. You connect your technical decisions to the people using what you build, and you care about the outcome, not just the implementation
• Strong cross-functional collaboration skills with your engineering peers, senior PM, ML/DS partners, and leadership. You care more about the system landing than about being right
• A pragmatic default paired with a strong systems instinct – you look for root causes, not symptoms
• Hands-on experience with agentic engineering tools and workflows in a real production setting
• Experience reading and understanding complex code, owning code quality and improving it
• Critical thinking and problem solving skills working in a high growth environment where stakes are high
• 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
• Nice to have - Provides technical leadership on Rust best practices - idioms, safety, and performance as the team scales its adoption across greenfield projects
