About us

B2B payments are a multi-trillion-dollar industry and, as the industry pushes further into digitization and faster settlement, fraud has become a massive problem — to the tune of $43B in annual losses.

Walrus is the leader in B2B payment verification, with clients that include some of the biggest names in investment management. Our DoubleCheck platform combines advanced authentication, proprietary technology, AI, and novel UX to collect and confirm payment details. DoubleCheck has defined a new category: verifying the safe transfer of financial information and assets.

Walrus is led by PhD computer scientists and security researchers, with decades of experience in engineering, cybersecurity, and cryptography, and many research accomplishments at Harvard, Stanford, MIT, the University of Chicago, Columbia, UTexas, and NYU.

We’re backed by one of the world's leading fintech VC funds, as well as founders and former executives of Twitter, Google Maps, Databricks, and Kayak.

The role

You will own the systems DoubleCheck runs on and the tooling our engineers use to ship it. Today that work is spread across several engineers on top of their product work. You will be the first person for whom it is the whole job.

What you’ll own:

• Production: uptime, deployments, health checks, error logging and alerting, and on-call response.

• Dependencies: keeping our stack, and everything underneath it, patched quickly.

• Developer platform: CI, the test suite, build and update scripts, and developer documentation.

• Access: who can reach production and production data, and how.

• Security of company systems: cloud identity and access policies, device management, and endpoint protection.

• Compliance: backups and retention, penetration tests and audits, and the technical side of client security questionnaires.

About you

• You have run production systems for a web application and been on call for them.

• You write code. Most of this job is automation, in a Python and Google Cloud codebase alongside the product engineers.

• You work without hand-holding: you find the biggest risk or the most fragile system, fix it, and tell people what you did.

• You have a solid understanding of both the strengths and weaknesses of AI tools.

• You can explain a security or reliability trade-off to someone who isn’t an engineer.

What it’s like to work with us

We’re a tight-knit, early-stage team that’s focused on building a product that our customers love. We have a strong company culture based on collaboration, ownership, and mentoring.
