Senior Software Engineer

Apply Description Senior Software Engineer (Full-Stack Mastermind) $200k – $220k / year Fully remote Description Most software engineers write code. We're looking for someone who changes the trajectory of a product. Do you thrive on owning a problem from the database all the way through the user experience? Can you move comfortably between designing an API, debugging a production issue, optimizing a SQL query, and improving a front-end workflow? Are you the type of engineer who sees a complicated problem, figures out what needs to happen, and ships a solution other people thought would take twice as long? And just as importantly: are you already figuring out how AI changes the way great software gets built? If so, read on. I'm the Head of Engineering at RTA, and I'm looking for a Senior Software Engineer to help build and evolve Fleet360, our fleet management SaaS platform. This is a high-ownership, high-impact role. You won't just be executing tickets. You'll be shaping solutions, making architectural decisions, working across the stack, and raising the engineering bar for the people around you. We are also serious about becoming an AI-first engineering organization. That doesn't mean blindly generating code and shipping whatever an LLM spits out. It means using AI as a force multiplier throughout the software development lifecycle: understanding unfamiliar code, exploring solutions, generating and reviewing implementations, writing tests, debugging issues, documenting systems, automating repetitive work, and dramatically increasing the speed at which a great engineer can deliver great software. We want engineers who are actively figuring out how to work differently because these tools exist. This role is not for everyone. If you prefer clearly scoped tasks, minimal ambiguity, staying exclusively in one layer of the stack, and steady incremental work, we'd still love to have you, just not in this seat. This role is for engineers who see an undefined problem and feel a pull toward it, not away from it. What we're looking for In general, someone who: Is a force multiplier. When you're on a project, the whole team moves faster and ships better. You raise the bar just by being in the room. Is passionate about serving others. Thinks like a product engineer, not just a programmer. You care about the outcome for the user, not simply whether your code works. Owns problems end to end. Front end, API, database, integration, production issue: you go where the problem takes you. Works AI-first. You actively use modern AI development tools to make yourself faster and more effective, and you're constantly experimenting with better ways to use them. Knows that AI output still requires engineering judgment. You validate assumptions, understand generated code, test aggressively, and never confuse speed of generation with correctness. Has strong opinions, loosely held. You push back when something is wrong, but…
