Senior Software Engineer

About the job

Our company builds a modern operations platform for oil delivery businesses. Heating oil dealers across the northeastern US run mission-critical daily operations (dispatch, routing, deliveries, billing) on decades-old software and paper tickets. Our platform runs the entire delivery workflow: customer and tank management, pricing, dispatch, route optimization, and an offline-first driver app, with automated delivery forecasting on the roadmap. In oil delivery, every truck-hour counts and a missed delivery in January is a frozen home. We help dealers run more gallons per truck with less office overhead.

About the Role

We're looking for a Senior Full-Stack Software Engineer who thrives at the intersection of engineering and product thinking. You'll own features end-to-end: design, build, launch, and iterate across our stack, including the dispatch and back-office web app, the offline-first driver experience, routing API integrations, and the data layer that powers delivery forecasting. Your work goes live in October running a real oil dealership's daily operations through the winter heating season.

We care deeply about both product quality and speed. We ship fast, but everything that ships gets reviewed: all core code goes through a code review, and we hold each other to a high standard on correctness, reliability, and user experience.

This is a full-time contract role, working with significant overlap with the US Eastern Time Zone. You'll work directly with the technical founder, a former J.P. Morgan trading-systems engineer who stays hands-on in the codebase while driving the business. We are currently a team of two and looking to bring on a founding engineer.

What You'll Do

• Own feature development from database schema to driver-facing experiences.
• Build our offline-first driver experience (service workers, local persistence, sync on reconnect) for trucks that lose signal on rural routes.
• Integrate routing and optimization APIs with dispatcher override workflows.
• Participate in code reviews, both giving and receiving direct, constructive feedback on pull requests.
• Hold a high bar for code quality, reliability, and monitoring. This system runs a oil business in a northeastern winter, where downtime has real-world consequences.

• Prioritize ruthlessly against an October go-live and navigate evolving domain requirements with autonomy.

   

What You'll Bring

• 4+ years of full-stack engineering experience with production systems people depended on.
• Strong Python (Django or Flask) and solid TypeScript/React skills.
• Strong PostgreSQL and relational data modeling; multi-tenant schema experience a plus.
• Comfort owning third-party API integrations (mapping and routing, payments, QuickBooks a plus).
• Strong familiarity with AI-assisted development tools (Claude Code, Copilot).
• A balance of speed and craft: you ship quickly without cutting corners that matter, and you welcome code review as part of how good software gets built.
• Low ego, high autonomy, resilient against a hard deadline.
• Proactive and precise communication in English. You'll work async across time zones.
