About the Developer Impact Team

The Developer Impact team boosts the effectiveness and velocity of Zapiers engineering organization by improving developer workflows tooling and processes with a strong focus on AI-powered developer experiences and cutting-edge productivity tooling. Were not a traditional DevEx team. We take a hypothesis-driven experimental approach dogfooding lightweight solutions measuring their impact and rapidly iterating. We aim to eliminate friction across the software development lifecycle partnering closely with other platform and product engineering teams to create a seamless high-velocity developer impact.

If youre passionate about high-leverage internal platform work and love experimenting with how AI and automation can transform how developers build software youll thrive here.

Youll Love This Role If

• You get energy from improving how engineers work not just what they build.

• You enjoy building high-leverage tools that multiply impact across dozens of teams.

• Youre passionate about using AI to push the boundaries of developer productivity.

• You thrive in a collaborative experimentation-driven environment where learning fast matters as much as shipping fast.

About You

• Youre a Full-Stack builder: You have 6 years of professional software development experience (including 2 years in a senior or tech lead role) and experience with Python and Typescript. Youre strengths are in building resilient backend services and APIs as well as responsive but you know how to build intuitive frontend interfaces using modern frameworks.

• You have a Developer Platform Mindset: Youve built tools frameworks or infrastructure that other developers rely on daily. You think about developer workflows holistically from local dev to CI/CD and you design for scalability and maintainability.

• Youre Savvy and using AI Developer Tools: Youre familiar with AI-assisted development. Youve worked with AI pair programmers code review bots or ML-driven CI optimization. Youre eager to explore practical measurable ways AI can improve engineering velocity.

• Youre Experimentation & Impact Focused: You thrive in a fast-moving environment that values experimentation. You use data and feedback to validate ideas and iterate quickly. You see failure as a learning opportunity.

• Youre Collaborative Builder: You work closely with engineers across platform and product engineering teams to identify pain points and co-create solutions. You treat engineers as your customers and focus on delivering tangible improvements to their experience.

• You Care About Documentation & Knowledge Sharing: You write great documentation share best practices and raise the bar for engineering excellence. You care as much about improving team workflows as you do about shipping code.

• Youre a Strong Systems Thinker: You understand how decisions in CI/CD testing infrastructure or local dev environments ripple through the broader engineering ecosystem.
  

Things Youll Do

• Build Internal Developer Tools & Platforms: Design develop and maintain internal products that improve developer productivity and flow. Youll build across the stack from command-line utilities and IDE extensions to web dashboards and APIs that streamline development workflows.

• Integrate AI into Developer Workflows: Build and integrate AI-powered experiences that augment how engineers build test and deploy software.

• Collaborate with Engineering Teams: Partner with engineers across the company to understand friction points in their workflows. Conduct interviews shadow developers and gather feedback to inform priorities. Youll balance solving immediate pain with building scalable solutions.

• Create and Evolve Golden Paths: Help define and promote standard high-velocity development patterns. Maintain service templates example apps and internal frameworks that guide engineers toward best practices.

• Enhance CI/CD and Developer Workflows: Partner with DevOps and Reliability teams to improve how code moves from laptop to production. You might optimize build caching implement smarter test runners or integrate automated quality checks into CI.

• Dogfood Measure and Iterate: Use the tools you build. Gather both quantitative metrics (e.g. build time deploy frequency) and qualitative feedback to assess impact and guide iteration.

• Contribute to Developer Documentation: Maintain clear discoverable guides for internal tools frameworks and best practices ensuring engineers can quickly get up to speed and stay unblocked.

• Mentor and Influence: Lead by example through thoughtful code reviews internal talks and knowledge sharing. Help shape the technical direction of the team and contribute to its roadmap.
