Sr. Software Engineer

Pendo's engineering teams build the product experiences that help customers understand, improve, and act on product usage data. This team is focused on AI-powered features that turn raw usage signals into automatic, actionable suggestions, reducing the manual work customers need to do before they can get value from Pendo. As a Senior Software Engineer, you will help shape and ship intelligent product experiences from discovery through delivery. You will work full-stack with a lean toward frontend, using TypeScript, Vue.js, backend services, and AI coding tools to build high-quality features on a small, fast-moving team. This role is based in our Sheffield office.

Responsibilities

AI-powered feature delivery: Build and ship features that use AI to turn product usage data into actionable suggestions for customers; Full-stack engineering: Own delivery across the frontend and backend, with a strong lean toward TypeScript, Vue.js, DOM-level work, component architecture, and in-browser data capture; Product discovery: Help validate problems, shape scope, and test direction before and while building; Success metrics and iteration: Define what success looks like for the features you build and use product usage data to guide iteration; AI-enabled development: Use AI coding tools such as Cursor and Claude Code as a core part of your daily workflow; AI product quality: Ship AI-backed features with careful attention to latency, hallucination, inconsistent output, and user trust; Cross-functional collaboration: Work directly with product, design, and fellow engineers in a small team where ownership and leverage matter; Engineering standards: Raise the quality of the team through code review, mentorship, and unblocking teammates

Requirements

Hands-on experience building with LLMs and AI agents, whether through production work or personal projects; Full-stack engineering experience with a frontend lean, including strong TypeScript skills, comfort working with the DOM, and the ability to reason about backend services; 3+ years of experience building and scaling web applications; Strong product judgment, including comfort owning ambiguous problems, shaping scope, and making decisions without a fully specified brief; Experience defining success metrics for a feature and iterating based on real usage data; Experience engaging directly with customers or end users to validate problems and assess impact after launch; Strong grasp of software architecture, design principles, and API development; Clear communication skills and the ability to mentor others, unblock teammates, and support the growth of the engineering team

Nice to have

Experience working as, or closely alongside, a product manager, including writing specs, prioritizing a roadmap, or running discovery; Familiarity with product analytics tools such as Pendo, Amplitude, or Mixpanel to measure feature impact; Experience designing or running experiments, including A/B tests or betas, to validate product decisions; Experience with browser DOM inspection or automation; Familiarity with Model Context Protocol or building tools for LLM agents; Familiarity with real-time data pipelines or streaming architectures; Accessibility experience; Passion for continuous learning and sharing insights with the team
