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.

We recently announced $14.4 million in funding to make blockchains & digital assets useful for the world. Founded by Jump Crypto alumni and core contributors to the Solana protocol and the Firedancer client (https://github.com/firedancer-io/firedancer), we’re tackling fundamental scalability, performance, and usability challenges in distributed ledgers. Our runtime conforms to the RISC-V specification—moving away from domain-specific VMs, DSLs, and bespoke compiler toolchains that limit developer and institutional adoption. Components are developed in C for maximal control over performance and resource usage.
Interesting problems you’ll tackle:
- Building and testing high-performance subsystems in C (cryptographic routines, consensus primitives, networking protocols)
- Designing robust process isolation on modern CPU architectures and tile-based multi-core layouts
- Optimizing memory hierarchies, cache utilization, and low-level I/O for commodity servers
You:
- 5+ years of systems programming in C/C++, Rust, or similar
- Deep expertise in CPU microarchitecture, memory subsystems, and low-level performance tuning
- Strong understanding of distributed systems design and consensus protocols
- Experience with high-performance networking and protocol design in real-time environments
