Senior, Software Engineer

WHY DEPT®? We are a Growth Invention company built to help the world’s most ambitious brands grow faster. Operating at the intersection of technology and marketing, we create what is next by pioneering ideas, acting fast, and moving further because standing still just is not in our DNA. We are drawn to people who stay curious, move with intent, and never stop inventing. Our culture runs on three values: better together, relentlessly curious, and get sh*t done. It is how we work, how we grow, and how we make things that matter. At DEPT®, you will find the freedom to explore, the space to collaborate, and the trust to make a real impact for our clients, for each other, and for the world we are helping to build. The role As a Senior Engineer, you own significant portions of a project and drive them to completion. You take a semi-defined problem, ask the questions that sharpen it, turn it into a plan, and ship it. You're past the stage of needing fully specified tasks handed to you, and you're building the judgment to know which task matters most. You're comfortable working alongside product managers, engineers, marketing, sales, and finance, and you can explain your work to any of them without retreating into jargon. Most of what we build depends on getting those people to a shared understanding of what's being made and why. This role is primarily backend focused, occasionally diving into cloud infrastructure. However, you should also be comfortable enough in a modern frontend codebase to apply best practices and create something visually appealing and smooth to use. What you'll do Build and deploy scalable backend services and APIs for global brands, taking high ownership of your workstreams and their dependencies. Take specs that are incomplete or ambiguous, resolve the open questions, and turn them into clear requirements, tasks, and stories with time-to-complete estimates people can plan around. Participate in technical design of systems, schemas, and pipelines, and offer sound guidance on architecture and infrastructure decisions. Integrate third-party APIs and systems, and design the contracts that frontend teams and other services build against. Perform code reviews that raise the bar, both submitting your own work and giving constructive feedback that makes your teammates better. Surface technical blockers, risks, and client-facing issues early enough for the team to course-correct. Advocate for best practices in testing, security, performance, and CI/CD, and encourage others to do the same. Work directly with working-level client stakeholders over email, on calls, and in person, and start building demo and presentation content of your own. Apply AI and agentic capabilities to real client work, and contribute back to how the craft adopts them through reusable templates, prototyping sessions, and practical guidance for other teams.
