Stateless | Boulder, CO | Onsite | stateless.net

At Stateless we are building something special. Not just in terms of a disruptive technology but also in terms of culture. A culture were people authentically personify our organizational values. Supportive. Sincere. Studious. Striving. Stateless.

Stateless is on a mission to reinvent network connectivity. Central to that was our initial innovation, where we demonstrated an ability to efficiently decouple state from processing in network functions—a task deemed infeasible in high-performance networking systems, but in doing so, we have opened the door for fundamentally changing how networks are built. Now, we are building the product around that vision. VCs have backed us, and early adopters have validated the business opportunity.

We are hiring for a variety of roles: from C++ Python and Kotlin developers to sales and support engineers.

Open positions:

* High Performance Network Programmer - https://boards.greenhouse.io/stateless/jobs/4285482002

* C/C++ Programmer - Networking Programmer (Mid to Senior Level) - https://boards.greenhouse.io/stateless/jobs/4375649002

Southeast USA including: Virginia (Arlington and Dulles), Maryland (Annapolis Junction), South Carolina (Greenville), Alabama (Huntsville), Florida (Melbourne), Texas (Austin and San Antonio), Pennsylvania (State College) and possibly others, all ONSITE. Citizenship is a job requirement.

We do emulators, JIT, hypervisors, stuff similar to valgrind, debuggers, manual disassembly, binary static analysis, parsers, and assembly. We write our own low-level tools, frequently in C99 to run on Linux. We also use IDA Pro, ghidra, qemu, Simics, JTAG debuggers, gdb, Coverity, KlocWork, LLVM, and so on. Easily transferable skills include those related to compilers, kernel drivers, embedded RTOSes, vectorizing, firmware, VxWorks BSP development, symbolic execution, boot loaders, software verification, concolic testing, abstract interpretation, satisfiability (SAT, SMT) solvers, and decompilers.

Common degrees include Computer Science, Computer Engineering, Electrical Engineering, and Mathematics.

We don't normally work overtime, and we get paid more if we do. We're never expected to take work home or be on call. Because of the citizenship requirement, there is no chance that the work will be outsourced. Flex-time is fairly extreme; some do randomish hours.

Location hints: Pick Arlington for a car-free life, subway included. Pick Florida or Texas to live in a place with solid gun rights and no state income tax. Pick Florida for almost no traffic or commute, surfing, and a median house price of about $150,000.

[still-unnamed startup in stealth mode] | REMOTE or ONSITE(around HK: Guangzhou,Macau,Shenzhen,Taiwan,etc) | 20-40h per week, freelancers/full-timers/part-timers

Sorry for the vague description but I can tell you more about the product we're building when you apply. Hopefully I can attract you in a sufficient way with our tech stack! (see below). [NOTE: this is not a pie-in-the-sky venture, you would be joining a team who has a 1.5+year-old working product, with prospects of new greenfield products built around the first.]

Job positions:

- Build engineer: you are a Linux-er who has some past experience building deb or rpm packages, are excited about reproducible builds, and are willing to learn (if you don't already know) new things such as snap or flatpak. gitlabCI and/or githubActions is a plus. (Might do some DevOps work after we come out of stealth mode as well; with Pulumi and RedShift.)

- C#/.NET developer: generics, LINQ, VisualStudio, EntityFramework et al are your bread and butter. You value the diversity that comes from learning other languages and tech-stacks but also the stability that a robust platform like .NET provides, which you based your career on. Desirable to be familiar with Xamarin, but not required. F# is a plus.

- Rust developer: you dealt with C/C++/Objective-C in the past but are ready to move on. However, you're still not convinced about garbage collected languages, so you have been looking at Rust lately, or willing to learn it. You're not a smart-ass though, so you would be excited to expose your Rust code's API to be consumed by higher level languages.

- FP developer: you value immutability and lack of side effects because you have lived the nightmares of race conditions and heisenbugs in your career. You're disgusted with most job positions out there because the tech-stack described in most of them don't look safe enough to be serious (sure they can build snapchats with them, but not robust software that would end up being used by NASA or Waymo). Desirable to be familiar with F#.

- Desktop/mobile developer: you cringe at the idea of "Electron apps", because you think native frameworks like QT or gtk+ give much power and maintainability (plus, performance aside, javascript is a joke in any other aspect too). But you also understand why garbage-collected languages are safer and more productive than low-level ones, and there are many of these much more decent than JS. (gtk is preferred for this position at the moment; or someone willing to switch)

- SmartContracts/blockchain developer: you've used/developed smart contracts in languages such as Ivy, MiniScript, or Solidity(EVM), or are willing to learn this technology. Desirable to have familiarity with atomic swaps, HTLCs or zero knowledge proofs. Excited about things like bitcoin, ethereum, mimblewimble/grin, DAI, etc

Important perk for all positions: all the code/scripts you'll write (being paid of course) will be opensource, at least for the first 3months.

Write me at andrew.forsure@gmail.com

PS: Abstain from applying if you expect a lead/managerial role, because the team is not yet big enough to need extra leadership for now.

PS II: In case you're only interested in joining part-time, note: I wouldn't find it acceptable if you join us to work remotely part-time while keeping your full-time job. Part-time only works with your own side-projects, or other additional part-time job (because resting is important).
