About Tank Track

Tank Track is the leading SaaS platform purpose-built for septic, grease trap, and portable toilet service businesses. From single-truck owner-operators to large fleets, our software helps thousands of companies across the country manage scheduling, routing, invoicing, compliance reporting, field operations, and more. We're a small, high-impact team building software for an industry that's long been underserved by technology — and we're just getting started.

About the Role

We're looking for a Senior Software Engineer to join our four-person engineering team and play a central role in shaping the future of our platform. You'll work across the full stack — building new features, improving existing ones, and contributing to our mobile app built in React Native.

Our current stack is PHP-based, and we are actively migrating to Node.js and React. You'll be hands-on with both the legacy codebase and the modern stack, helping us execute this transition thoughtfully while continuing to ship features our customers rely on every day.

This is a high-ownership role on a small team. You won't be waiting for tickets to be assigned — you'll be collaborating directly with product and customers to understand problems and build solutions.

What You'll Do

Design and build full-stack features across our web platform and React Native mobile app
Contribute to the ongoing migration from our PHP codebase to Node.js and React
Write clean, well-tested, production-ready code that scales with our growing customer base
Collaborate closely with the team on architecture decisions, code reviews, and technical direction
Work directly with product and customer-facing teams to understand user needs and translate them into technical solutions
Improve developer experience, tooling, and processes as the team grows
Help establish patterns and best practices for the new Node.js/React stack
What We're Looking For

5+ years of professional software engineering experience
Strong full-stack development skills with hands-on experience in both backend and frontend work
Production experience with PHP — you're comfortable working in a legacy PHP codebase and don't need hand-holding to be productive in it
Solid experience with Node.js and modern JavaScript/TypeScript
Experience building or contributing to React Native mobile applications
Familiarity with React for web
Experience with relational databases (MySQL or PostgreSQL)
Comfort working in a small team environment where you own features end-to-end
Strong communication skills and a collaborative, low-ego approach to engineering
Nice to Have

Experience with large-scale codebase migrations (PHP to Node/React or similar)
Familiarity with REST API design and third-party integrations (payment processing, mapping/routing, etc.)
Experience with cloud infrastructure (AWS, GCP, or similar)
Background in field service, logistics, or SaaS platforms serving blue-collar industries
Experience with CI/CD pipelines, automated testing strategies, and DevOps practices
Why Tank Track

Small team, big impact — You'll be engineer #5 with real influence over the product and technical direction
Real-world impact — Our software helps essential service businesses run more efficiently every single day
Modern stack migration — A rare opportunity to help architect a greenfield Node.js/React system while drawing on lessons from the existing platform
Customer-obsessed culture — We build close relationships with our users and ship software that solves real problems
Pay: From $7,000.00 per month
