Propel builds technology to strengthen America's social safety net, serving over 5.5 million Americans accessing SNAP, Medicare, and other government benefits. The company has grown revenue 35% YoY and is reinventing how benefits are delivered—making complex government systems as seamless as consumer apps like Apple Pay or Netflix.
As a Senior Full Stack Engineer, you'll own meaningful product work across the entire stack: mobile apps (Vue, TypeScript, Capacitor), backend systems (Python, Flask, Postgres, Redis, AWS), and new product lines. This is not a ticket-taking role. You'll help identify problems, shape solutions, and ship iteratively in a space shaped by policy changes, evolving technology, and real-world constraints.
You'll work closely with Product and Design to scope and execute solutions, break ambiguous problems into shippable components, and contribute to architecture and technical direction. The engineering culture is lean and transparent—you'll understand revenue drivers and big bets. Engineers have meaningful heads-down time; the company is not meeting-heavy. Product, Design, and Engineering operate with shared values (curious, empathetic, user-first), which reduces friction and accelerates execution.
You'll participate in on-call rotation, contribute through design and code reviews, and mentor teammates. The role requires comfort with ambiguity, strong product instincts, and a bias toward action. You'll build systems used daily by millions of Americans to access food, healthcare, and financial stability.
Required: 5+ years building and maintaining complex full-stack systems, experience in startup or high-ambiguity environments, strong system design and product engineering fundamentals, fluency in Python and JavaScript (or willingness to ramp quickly), and clear written and verbal communication. Nice-to-have: experience building consumer-scale applications and familiarity with safety net programs (SNAP, WIC, TANF, SSI, SSDI, Medicaid, Section 8).
The company operates in the complex intersection of people, policy, and government systems. Priorities can shift as policy, partners, or user needs evolve. Engineers move across product surfaces and problem spaces. The roadmap is influenced by legislation and regulatory changes, so external uncertainty is inherent. Career growth comes through ownership, impact, and stretch work rather than predefined ladders.
