What you'll do

  • Design and build core parts of our transaction platform.
  • Build for correctness under failure, with the isolation and auditability a regulated product needs.
  • Scale the platform as transaction volume and the number of institutions per node grow, keeping latency predictable and the database healthy.
  • Write design docs for what you build, and give sharp, useful reviews on other people's designs and code.
  • Build with AI agents every day, and help improve the specs, context and review practices that make agent-written code safe to ship in a regulated product.
  • Work with product, compliance and customer-facing teams to turn regulatory and customer needs into working software.
  • Own what you ship in production, from tracing and alerts to incident follow-ups.
  • Mentor engineers on the team.
  • Work on an on call rotation

What we're looking for

  • Systems design depth: designed and owned distributed systems where correctness matters more than features; knows asynchronous processing well and can reason about what happens when parts of it fail.
  • Strong Go, or deep production experience in another statically typed backend language (Java, Kotlin, Rust, C#) and the appetite to be shipping Go within your first weeks.
  • PostgreSQL in depth: schema design, query plans, locking and isolation levels, migrations on live systems, and multi-tenant data.
  • End-to-end ownership in the cloud: working knowledge of AWS or GCP (IAM, networking, managed databases, queues and storage); can read and change Terraform and debug production from traces and logs.
  • AI-native engineering: uses coding agents such as Claude Code or Cursor every day and can show how; writes the specs and context, breaks work down for them, and reviews their output as hard as a human pull request; knows where they fail.
  • Staff-level experience: a track record of delivering large, technically hard projects end to end and helping the engineers around you get better; typically 8+ years building backend systems.
  • Clear, concise writing in a remote company that makes decisions in documents and async threads.
  • Security fundamentals for sensitive data: encryption in transit and at rest, key handling, minimising personal data, and least-privilege access.

Nice to have

  • Applied cryptography: encryption, signing and key management.
  • Decentralized identity: DIDs, verifiable credentials, DIDComm.
  • Regulated finance, payments or compliance: Travel Rule, AML, ISO 20022.
  • Building and running software under SOC 2 or ISO 27001 controls.
  • Crypto and blockchain knowledge: chains, addresses, assets, CAIP identifiers.
  • Node.js and TypeScript.
  • Queue and workflow systems, and modern observability tooling.

Benefits

  • Flexible Remote Work: Work from anywhere!
  • $1000 WFH Stipend: Use within your first year of employment.
  • MacBook Pro: Procured by you and your manager to find a model that meets your needs.
  • Unlimited PTO: We trust you to take as much holiday as you need.
  • Country-Specific Benefits: Statutory offerings and contributions, managed via our employer-of-record.
