Build the security platform of the next 50 years.
LumixSys is 142 people across Boston, London, and Singapore — and remote everywhere else. We're hiring at every level across cryptography, AI, platform, product, design, and security operations.
We do hard things well. We work with people we'd follow into a foxhole.
We're a research lab that ships product. Half of our engineers have published at IEEE S&P, USENIX Security, or CRYPTO. The other half have shipped runtime security to a billion users. We pair those people deliberately — research informs product, product disciplines research.
We pay 75th percentile cash, 90th percentile equity, and we use a transparent leveling rubric with publicly-posted bands. We don't negotiate with one candidate harder than another. We don't cap parental leave. We don't monitor your hours. We do measure outcomes — clearly, publicly, and quarterly.
Compensation, time, and care — at parity with the best in tech.
100%-paid premium medical, dental, vision, and mental health for you and your family. Worldwide.
Unlimited PTO with a 4-week minimum. The exec team takes 5+. We track and enforce it.
20 weeks fully paid for all parents. Phased return-to-work. No tenure requirement.
Early-exercise stock options. 10-year exercise window. Quarterly secondary windows for tenured employees.
Work from anywhere we can legally hire. Quarterly team gatherings at one of our offices.
$3,500/year for conferences, certifications, books — including offensive-security training (yes, OSCP counts).
Four operating principles you should expect.
We invest in tooling, testing, and architecture review. Brilliant jerks aren't worth it.
Every employee is on rotation to read incident postmortems and customer interviews.
We write design docs before we write code. We publish quarterly Trust Reports.
We'd rather hire one Principal than two Seniors. Compensation reflects that.
Find your seat. We're hiring across every team.
If you don't see a role that fits but you'd bring something real — write us. Every email is read by a hiring manager within 48 hours.
