ABOUT SEQUENCE If you join Sequence, you'll help build the platform that lets companies get paid - we’re already processing $1bn+ in annual invoice volume and growing fast. We're building the AI-powered revenue platform for modern finance teams, replacing fragile spreadsheets and legacy systems with software their teams love using. Cognition, incident.io, MoonPay, and 100+ other high-growth companies trust us to handle their entire revenue cycle across quoting, billing, and revenue recognition. Founded by repeat entrepreneurs, we hit 10x ARR growth last year and just closed a $20M Series A https://www.sequencehq.com/blog/sequence-announces-series-a led by 645 Ventures, alongside a16z and exceptional founders and CFOs from companies like Decagon, Klaviyo and Wise. WHAT'S IT LIKE TO WORK AT SEQUENCE? Small team, big opportunity, real ownership. You'll do work that matters, have direct access to customers, and grow alongside the company. If you want to do the best work of your career at a company that's scaling fast, we'd love to meet you. WHAT YOU'LL BE DOING We care deeply about the quality of the product we're building. We're looking for engineers who are ambitious and take ownership end-to-end: from identifying what to build, through shipping, to making sure it works for real customers. Here’s what you might work on: - AI-powered workflows. Our customers spend hours on repetitive busywork - chasing approvals, sending payment reminders, routing exceptions. You'll build flexible systems that customers configure in natural language - "require VP approval for deals over $100k with annual terms" - and that needs to translate into something they can understand, trust, and debug. - Human-in-the-loop systems. Automation only gets you so far. You'll build the interfaces that bring the right people in at the right time, with the right context: approval chains that flex to each company's rules, escalation flows that surface what matters, and dashboards that make complex workflows legible at a glance. It requires the obsessive attention to detail that makes our customers genuinely love using the product. We're a lean team growing to 20+ engineers. You'll have real influence on what we build and how we build it. Early enough to shape fundamental architecture. Late enough that customers depend on what you ship. WHAT OUR NEWEST HIRES HAVE SHIPPED Watchtower: our command center for AI agents. As we introduce agents that automate financial workflows, customers need visibility and control. This included building our first agent - a contract intake system that extracts customer and pricing information from uploaded or emailed contracts, taking customers from signed contract to automated billing in minutes. A fully integrated e-signature experience for quotes. When a customer is closing a deal, friction kills momentum. We rebuilt the signing experience - including embedded authentication and branded emails - into a seamless signing experience used by teams at the top tech companies every day. Role-based access controls across the product. Different companies have different structures, but they all need tight control over who can approve deals or access sensitive data. This meant designing a flexible RBAC model that handles resources across surfaces. See more of what we’ve shipped in our public changelog https://www.sequencehq.com/changelog. YOU SHOULD APPLY IF You're a builder who wants to solve problems end-to-end: - You’ve built and shipped high quality web apps in product-lead businesses - You have experience with modern front-end development (e.g., React, Typescript) - You have a keen attention to visual detail and can faithfully bring UX to life - You care about customers - you want to understand why you're building something, not just what - You’re comfortable with ambiguity. You thrive in early ideation stages, share work-in-progress to gather feedback, and adapt easily based on input - You communicate clearly. Thoughtful communication is a superpower that sharpens how we collaborate and build This might not be right if We're a small team moving fast on hard problems. That might not be a fit if you: - Enjoy larger organisation structures and staying only within your area of expertise. Taking ownership here means doing whatever the problem needs - Want a traditional engineering team set up, with a predictable roadmap and clearly scoped out tickets provided for you - Prefer a slower pace. Customers are depending on what we ship - Aren't comfortable with production responsibility. We're revenue-critical infrastructure - on-call matters here TECH STACK We hire for ability, not a specific tech stack. Here’s what we use: - Frontend: TypeScript, React, Tanstack Query, Jotai, Playwright - Backend: Kotlin, Postgres, BigQuery - Infrastructure: Google Cloud, Vercel, Terraform - Monitoring: Google Cloud Monitoring, Sentry, PostHog - Tools: GitHub, Slack, Notion, Linear Read our engineering principles https://sequencehq.com/blog/engineering-principles HOW WE WORK We’re based in London and New York and love spending as much time with our colleagues as possible. We spend three days together in the office, with team lunch on Wednesdays. You'll join a cross-functional product team working directly with design and product.
