Transmit Security median: 35 days open

The posting

We offer the industry’s only platform that fuses customer identity and anti-fraud solutions: customer identity management, identity verification, and fraud prevention. We sell to industries with large, consumer-facing businesses such as banking, financial services, insurance, fintech, gaming, ecommerce/retail, telco/media, and utilities.

About the Role FlexID is Transmit Security’s identity orchestration platform, trusted by some of the world’s largest financial institutions, including Citi, HSBC, UBS and, here in Israel, Bank Leumi, to authenticate millions of their customers. We’re looking for a senior backend engineer to build and evolve a mission-critical system where reliability, security and correctness really matter.

What you’ll do:

  • Build new features: login flows, passkeys (FIDO2/WebAuthn), device binding, policies and APIs
  • Write backend code every day. We're in Scala, with Akka, MongoDB, Postgres, Redis and Kafka
  • Keep the codebase healthy: upgrade stuff, fix vulnerabilities, add tests, clean things up without breaking customers
  • Dig into real production issues when a customer needs help, and enjoy solving them
  • Help teammates grow through reviews and good conversations
  • Use AI tools like Claude Code day to day

What you’ll need:

  • B.Sc. in Computer Science or Engineering from a leading university
  • 5+ years building large-scale backend systems
  • Strong system design and architecture skills
  • Strong backend experience in Java, Scala, C#, or TypeScript. We develop with Claude Code, so strong engineering fundamentals matter more than any specific language
  • An ownership mindset: independent, persistent, and focused on getting things done

Nice to have:

  • Identity management / authentication protocols (OAuth, OIDC, SAML, FIDO)
  • Web security experience
  • Experience delivering enterprise software, both on-prem and cloud
  • Hands-on experience with AI coding tools (Claude Code, Cursor, etc.)

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
