Formal | Multiple Positions | REMOTE | Full-Time | $100k - $250k + Equity

We're building a new computing stack with formally verified data, memory, and resource isolation between executions for instant, truly elastic global compute. This includes designing and building a production language in a way that's never been done before, with complete, mechanized formal specifications and a certifying compiler from the start. Our immediate goals include an alternative to eBPF and building the world's first serverless networking infrastructure.

We are VC funded with runway for multiple years. The team is composed of PhDs from Stanford, UW, OSU, and Brown, advised by professors from MIT and UWaterloo.

We are currently hiring for the following positions:

- [1] Staff Software Engineer: Compilers, Programming Languages, and Verification ($175k - $250k + ≥ 0.4%)

- [2] Formal Verification Engineer: Formal Methods and Programming Languages ($120k - $200k + ≥ 0.2%)

- [3] Software Engineer: Compilers and Programming Languages ($100k - $175k + ≥ 0.1%)

- [4] Formal Methods PhD Intern: Formal Methods and Programming Languages ($10k / month)

Please see [5] for general information. Apply via our job board [6].

Formal | Multiple Positions | REMOTE | Full-Time | $100k - $250k + Equity

We’re [0] rethinking serverless from scratch, building a new computing stack for instant, globally available, truly elastic, soundly isolated execution. We leverage formal methods and languages to build OS interfaces with low overhead, formally verified isolation without containers or VMs. Our immediate goal is a new programming language to replace eBPF and build the world's first serverless networking infrastructure.

We are a 5-person, VC-funded team with PhDs from Stanford, UW, OSU, and Brown, advised by professors from MIT and UWaterloo. We are currently hiring for the following four positions:

- [1] Staff Software Engineer: Compilers, Programming Languages, and Verification ($175k - $250k + ≥ 0.4%)

- [2] Formal Verification Engineer: Formal Methods and Programming Languages ($120k - $200k + ≥ 0.2%)

- [3] Software Engineer: Compilers and Programming Languages ($100k - $175k + ≥ 0.1%)

- [4] Formal Methods PhD Intern: Formal Methods and Programming Languages ($10k / month)

If you haven't already, please feel welcome to send us a message! Even if these specific opportunities might not make sense, if this is something you're potentially interested in working on, perhaps there are other opportunities to be found. If nothing else, we're always excited to talk to anyone who's as excited as we are about the general direction.

Hi Geraldo! Thank you for the kind words, and for sending a message! The influx of responses has far exceeded any expectation I could have had, and I'm slowly but diligently responding as I go. Just wanted to let you know that I've received your message and I'm looking forward to chatting with you further. :)
