Job Posted: October 15th, 2025

Location: NAMER

Hi there! Zapier is looking for a Senior Full Stack Software Engineer to join our Developer Impact team, part of the Zapier Internal Platforms zone. We’re on a mission to make everyone more productive through the power of automation — and that includes our own engineers. Zapier has helped millions of people build businesses through automation. Now, we’re focused on giving our developers equally powerful tools and processes so they can build the future of automation with velocity and confidence.

About The Developer Impact Team

The Developer Impact team boosts the effectiveness and velocity of Zapier’s engineering organization by improving developer workflows, tooling, and processes — with a strong focus on AI-powered developer experiences and cutting-edge productivity tooling. We’re 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 you’re passionate about high-leverage, internal platform work and love experimenting with how AI and automation can transform how developers build software, you’ll thrive here.

About You

• Full-Stack Expertise: You have 6+ years of professional software development experience (including 2+ years in a senior or tech lead role). You’re fluent across the stack — building resilient backend services and APIs as well as responsive, intuitive frontend interfaces using modern frameworks.
• Developer Platform Mindset: You’ve 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.
• Applied AI: You’re familiar with AI-assisted development. You’ve worked with AI pair programmers, code review bots, or ML-driven CI optimization. You’re eager to explore practical, measurable ways AI can improve engineering velocity.
• 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.
• 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.
• 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.
• Strong Systems Thinker: You understand how decisions in CI/CD, testing, infrastructure, or local dev environments ripple through the broader engineering ecosystem.

Things You’Ll Do

• Build Internal Developer Tools & Platforms: Design, develop, and maintain internal products that improve developer productivity and flow. You’ll 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. You’ll 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.

You’Ll 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.
• You’re 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.
