Lightning Labs is hiring! We’re looking to expand our team to build technology that'll bring Bitcoin to the next billion people. Our current focus is the development and deployment of the Lightning Network, an open blockchain scalability protocol. We push the edge of innovation with regard to blockchain scalability, privacy-preserving smart contracts, and cryptocurrency UX. If you’re interested in one of the positions below, please apply using our careers page: https://lightning.engineering/join-us. And if you know someone who might be a good fit, we'd very much appreciate any referrals.
{Lightning Infrastructure Engineer}:
We're looking for a systems-oriented engineer who will design and build out key components to support the growth of the Lightning Network. These tools will lower the barrier to entry for operating Lightning nodes and enable existing node operators to more effectively manage their infrastructure. You'll work on products such as Lightning Pool (https://lightning.engineering/pool/), as well as other Bitcoin-based backend systems to make Lightning more useable, and secure.
{Protocol Engineer}:
Experienced systems software engineer versed in applied cryptography, peer-to-peer networks, distributed systems, open source software, and cryptocurrency protocols to design and implement core protocol and algorithmic components of the Lightning Network as well as the Bitcoin Network. Solid programming skills, experience with Go, C, or C++. Prior contributions to crypto protocols and open source software collaboration preferred.
Experience: Other than interns, we currently require a Bachelors degree in physics, engineering, math, computer science, or a related field, plus preferably 3+ years of work experience or a Masters or PhD in lieu of work experience. (Roughly 30% of our staff have PhDs.)
Technologies: Mostly C++23, Qt 6.5-6.9, CMake, git, OpenGL, CUDA, Boost, Jenkins. Windows and Linux, msvc/gcc/clang/clangcl. AI/ML and other projects use Python, some use Java or Javascript/Typescript/React.

Foxglove is the leading observability stack for robotics and physical AI. We accelerate robotics development through industry-leading logging, cloud dataset management, and visualization/analysis for multimodal data. We're well funded (Series A, ~35 people), and assembling the most talented team in the industry to build a platform for all robots. Sound interesting? Join us!
Prior experience working in the robotics industry is desired but not mandatory for most roles.
** San Francisco, CA **
- ML / Robotics Engineer, Dev Relations (python, c++, rust, ros, lerobot)
- Principal Research Scientist, Physical AI
** Sunnyvale, CA **
- Staff Software Engineer, Frontend / Visualization (typescript, react, webgl, rust / wasm, etc)
We are an early-stage, well-funded startup making humans and computers work together more efficiently. Experienced team from Apple AIML and other great companies.
We will be opening several roles soon, but are previewing this one early: Staff Engineer / Startup Polyglot Engineer.
You'll enjoy this role if:
- You like going 0 to 1 with high ownership: moving features and products from idea on a napkin, to prototype, to engineering UI, to shipped and polished product
- You are innovative, get satisfaction out of learning new things, and thrive in an environment of uncertainty and opportunity
To succeed, you should:
- Have the wisdom to know when to take the fast route vs when to step back and clean up your mess
- Be capable and excel on your own, but be humble and communicate well with others as projects require more collaboration
- Be versed across many programming languages (e.g. from C++/Java/Swift to Go to JavaScript or Python)
- Have worked on many types of projects and software -- have you built servers, written games, shipped native apps, and vibe-coded (kidding) web apps? If so, you're a fit.
- Be versatile and work both high level and low level, on old tech and new. Have you both prompt-engineered an LLM AND tweaked the code that decodes tokens in your own local LLM runner? If so, you're a fit.
All said, we're looking for the stereotypical "startup engineer" who can move between different components, be creative, be flexible, take ownership, and get things done. We have a complex, challenging product, but one that's amazing to work on and that will soon change how people think about working with each other and with AI.
