The French Sourcer Engineering hiring for engineering teams We have built R&D teams in France and the US, and turned that experience into a hiring system that helps you scale yours.

Forward Deployed Engineer - San Francisco

San Francisco, CA, United States · Permanent · On-site

Compensation: $170,000 to $250,000 USD base, plus 0.08% to 0.15% equity

Be the engineer the biggest customers call first at a fast-growing security startup, fixing their issues in hours and turning what you hear into the next features.

What you'd actually work on

  • Being the main technical contact for the company's largest accounts, taking in every question, bug report and feature request
  • Shipping bug fixes and product improvements quickly while working closely with high-value customers
  • Sitting with the engineering team to understand the detection logic, the product backend and its real constraints, so you can speak to customers with credibility
  • Leading early product discovery for new features based on real customer problems, then building those improvements back into the codebase
  • Representing the product's technical capabilities externally, including demos and trade shows, together with the go-to-market team
  • Working directly with the founding team, with no layer of hierarchy between you and the people making decisions

Where it gets technically interesting

  • An identity threat detection and response product protecting more than 2.5 million users across over 10,000 businesses, where every bug touches someone's security
  • A role that sits between code and customers: you need to understand detection engineering deeply enough to explain what the product can and cannot do, and then change it
  • Fast feedback loops, where a problem raised by a customer in the morning can be fixed and shipped the same day
  • A company scaling quickly, so the processes and tooling you build for customer-facing engineering will shape how the function works as it grows
  • A modern stack (Node.js, TypeScript, React, Python) and a small, very senior team, which means real ownership from day one

What we're looking for

  • 2 to 5 years as a forward deployed engineer, or as a software engineer at an early-stage company with direct customer interaction
  • Experience in a customer-facing engineering team with a high bar, or as a founder or early engineer at a startup who built products from scratch for clients
  • A computer science or closely related technical degree
  • Strong hands-on coding in TypeScript, React or Python, and the ability to write and ship production code
  • Clear, confident communication with customers, and comfort working across engineering and go-to-market teams
  • The habit of finding problems and shipping solutions without waiting for direction, including when the scope is unclear
  • Availability for up to 25% travel (trade shows, time on site with customers) and authorization to work in the US without visa sponsorship
  • Fluent English
  • Bonus: experienced engineers who want to return to a hands-on individual contributor role are welcome

The company

A Y Combinator-backed cybersecurity startup that reached mid-seven-figure annual revenue in under a year and is scaling toward more than $30M in the next twelve months. It wins the large majority of head-to-head evaluations against competitors and has very low churn. The founders come from leading security and finance companies, and the early team includes engineers and quantitative researchers from top-tier firms. This role comes with a path toward leading the function over time. Healthcare, dental, vision, 401(k), daily lunch and dinner, commuting stipend, gym discount and relocation support.
