Senior, Software Engineer

DEPT® is a Growth Invention company operating at the intersection of technology and marketing to help ambitious brands grow faster. The Senior Software Engineer will own significant portions of projects, primarily building scalable backend services and APIs while contributing to cloud infrastructure and frontend development. The role also involves technical design, client collaboration, code reviews, AI adoption, and mentoring through knowledge sharing.

Responsibilities:

• 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
• Share what you learn, internally through Slack, brown bags, and DEPT U, and externally through articles or talks as project work allows

Requirements:

• Proven experience building and maintaining production-level backend systems used by real people
• Strong proficiency in Python
• Experience designing and integrating APIs and third-party systems
• Solid working knowledge of database platforms, both SQL and NoSQL
• Enough familiarity with modern frontend development (preferably Angular and Typescript) to read the code, review a PR, and debug across the stack
• Experience with at least one major cloud provider
• Daily, real-world use of GenAI productivity tools (Gemini CLI, Claude Code, Codex) in your development workflow
• A working understanding of core LLM concepts and where they're a good fit for a problem
• Fluency with version control (git), Agile processes, and CI/CD tooling
• The ability to research independently and know when to ask for help, without spinning wheels on already-solved problems
• A track record of "getting sh*t done" in a fast-paced environment
• Google Cloud preferred
• Experience mentoring engineers earlier in their careers
• Exposure to agent development frameworks
• Contributions to open source, technical writing, or conference speaking
