Senior Engineer, Full-Stack (Ruby on Rails)

About Us

FIXD breaks car problems down into simple and understandable terms, so drivers don't get taken advantage of when they go to a repair shop. We create helpful tools and resources for drivers so that they can feel confident and informed whenever they have a car-related problem.

AppraisalPRO, a FIXD Automotive brand, helps car dealers spot hidden problems, value trades accurately, and win more deals. We provide dealers with immediate, precise repair cost estimates for thousands of mechanical defects, uniquely tailored to the make, model, year, trim, and geographic location of used vehicles. Our dealer-facing platform pairs a diagnostic sensor with subscription software to surface costly reconditioning needs, optimize trade-in values, increase profitability, and ensure fair deals for all parties.

Who we're looking for

• A senior-level, backend-oriented full-stack engineer who can take real ownership of a product — setting technical direction and driving features from idea to production
• An engineer who wants to help shape what we build, asking why behind a request, weighing trade-offs, and iterating quickly as we learn
• An analytical and data-driven person with the ability to communicate technical aspects to stakeholders
• Someone who enjoys hearing directly from customers, listening to dealer groups, understanding their workflows, and turning that into better product
• Someone who works well with autonomy in a small, fast-moving team, and is able to raise the bar for teammates as we grow

What you'll be doing

You'll help own AppraisalPRO end-to-end (backend, frontend, the app) and take a leading role in shaping our product and platform, with the autonomy to carry features from idea to production.

• Build and maintain AppraisalPRO across the stack, from our Rails backend and APIs to the dealer-facing web app and our React Native mobile app
• Own key architectural decisions across the stack and help set our technical direction
• Contribute to the API and SDK that make up our developer platform
• Collaborate with customers to understand their needs and translate them into features
• Design, implement, test, deploy, and maintain backend and frontend features
• Work closely with product to help deliver features and provide feedback on feasibility and timelines
• Write and maintain reliable Ruby and JavaScript/TypeScript code
• Create integrations with third-party APIs and services
