About the role

  • Cognition, incident.io, MoonPay, and 100+ other high-growth companies trust us to handle their entire revenue cycle across quoting, billing, and revenue recognition.
  • Small team, big opportunity, real ownership.
  • Here's what you might work on: - AI-powered approval workflows.

Responsibilities

  • We care deeply about the quality of the product we're building.
  • An intelligent collections agent. Chasing late payments is tedious, manual work. We're building an agent you instruct in natural language ("send a reminder at 7 days overdue; escalate at 14 days"), which then runs the entire workflow autonomously.
  • We're building revenue-critical infrastructure and currently rearchitecting our billing pipeline for an order of magnitude more throughput - rethinking storage strategies, horizontal scalability, and how we'll handle 10x load without 10x cost.
  • You'll have real influence on what we build and how we build it.
  • You'll design systems that process high-velocity event streams, make technical decisions that balance cost and performance at scale, and build infrastructure that never compromises on reliability.
  • You communicate clearly. Thoughtful communication is a superpower that sharpens how we collaborate and build

Nice to have

  • Deep relational database expertise.
  • We do a lot of complex queries and care about performance.
  • 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

Compensation

  • $210,000 - $230,000
  • You'll build flexible routing that customers configure in natural language - "require VP approval for deals over $100k with annual terms" - and turn that into deterministic, auditable business logic.
  • 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.
  • Salary: $210,000 - $230,000

Company info

  • a dropped event means someone isn't charged correctly.
  • An outage at month-end means finance teams can't collect revenue from their customers.
  • 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.
  • See more of what we've shipped in our public changelog https://www.sequencehq.com/changelog.
  • 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.
  • Late enough that customers depend on what you ship.
