Location: Lightning Labs Workplace: Remote Lightning Labs builds the infrastructure that makes Bitcoin work as a global payment network. Our protocols: the Lightning Network, Taproot Assets, and L402, are used by developers all around the world and are increasingly the rails that AI agents use to pay for services, stream value, and transact autonomously. We are looking for a full-stack engineer to help us build Terminal Web, the primary application node operators use to manage liquidity, channels, balances, swaps, and the rest of their Lightning operations. Location: Fully remote, with a preference for US time zones. THE ROLE This is a product engineering role centered on Terminal Web. You will take features from idea to production: understanding what node operators need, designing the user flow, integrating with Lightning services, building the frontend, shaping the API layer, writing tests, and sweating the details until the feature is ready to ship. You are the person we point at a product problem and trust to come back with something that works. Terminal Web is a TypeScript application built with Next.js, React, MobX, and Emotion. It uses server-side rendering, browser persistence, LNC-based RPCs to self-hosted litd nodes, and REST APIs to Lightning Labs services. The work spans UI, state management, API integration, data modeling, performance, reliability, and testing. The ideal candidate is comfortable moving across that stack without waiting for a narrow handoff. We use AI-native development tools heavily. Experience using Claude Code, Codex, Cursor, or similar tools as part of your daily engineering workflow is something we are looking for directly, not a nice-to-have. WHAT YOU'LL DO Ship end-to-end features in Terminal Web that help users operate Lightning nodes, manage liquidity, monitor activity, and interact with Lightning Labs products through a polished browser-based application. Build across the full stack of a modern TypeScript product: Next.js SSR, React components, MobX stores and view models, Emotion styling, IndexedDB-backed data services, LNC integrations, REST APIs, and the glue code that makes complex node operations feel simple. Own integrations with Lightning infrastructure by working with LND, litd, Lightning Node Connect, Loop, Pool, Taproot Assets, and related services. You will translate protocol and API capabilities into clear product experiences. Write production-quality tests with Jest and Playwright, and use those tests to move quickly without breaking the workflows node operators depend on. Work autonomously with minimal direction. Understand company priorities, identify where you can have the most impact, collaborate with product and engineering when needed, and execute from rough problem statements through launch. Use AI development tools as leverage for exploration, implementation, testing, refactoring, and documentation while maintaining the engineering judgment needed to ship secure, reliable software. WHAT WE'RE LOOKING FOR - You build and ship production-quality software. You have a portfolio, work history, or set of projects that demonstrate this, we'd love to see them. - You have strong TypeScript and React experience, and you are comfortable with modern full-stack web application architecture. - You have experience with server-side rendering, API clients, browser storage, state management, and the practical tradeoffs of building complex web apps for real users. - You use AI-native development tools such as Claude Code, Codex, Cursor, or similar as part of your normal workflow, not as a novelty. - You can take ambiguous product requirements and turn them into working software independently, while communicating clearly along the way. - You have strong engineering practices: automated testing, code review, documentation, debugging, and a bias toward simple, maintainable designs. - You care about product quality. You do not just wire up APIs, you think about the user, the edge cases, the loading states, and the failure modes. - You are excited about Bitcoin, Lightning, and the mission of making Bitcoin cheap, fast, and simple for everyone. NICE TO HAVE - Experience building wallet, payments, fintech, infrastructure, or developer tooling products. - Familiarity with Bitcoin, the Lightning Network, LND, litd, LNC, Taproot Assets, Loop, Pool, or related protocols. - Experience working with WebAssembly-backed browser integrations. - Experience with MobX, Emotion, Dexie, Bootstrap, visx, Jest, or Playwright. - Go experience or comfort reading backend services and protobuf-defined APIs. - Experience at a small, high-growth company where wearing many hats was the norm. Check out our github repos at: https://github.com/lightninglabs/lightning-terminal https://github.com/lightninglabs/lightning-node-connect https://github.com/lightninglabs/lnc-web https://github.com/lightningnetwork/lnd HOW TO APPLY We strongly encourage you to include links to projects, demos, writing, products, or anything else that shows how you build. A strong portfolio speaks louder than a keyword-optimized resume.

Location: Home based - Worldwide Canonical is a leading provider of open source software and operating systems to the global enterprise and technology markets. Our platform, Ubuntu, is very widely used in breakthrough enterprise initiatives such as public cloud, data science, AI, engineering innovation and IoT. Our customers include the world's leading public cloud and silicon providers, and industry leaders in many sectors. The company is a pioneer of global distributed collaboration, with 1000+ colleagues in 70+ countries and very few office based roles. Teams meet two to four times yearly in person, in interesting locations around the world, to align on strategy and execution. The company is founder led, profitable and growing. We have created a new career path at Canonical for Performance Engineers who bring exceptional clarity to software performance, correctness and efficiency. We are adding these roles to every engineering team at the company. As an open source platform, we have teams that work at every level of the software stack - from the kernel up through server and desktop applications, all the way to the web. We are adding roles with this focus in every engineering team in the company, to act as drivers of performance engineering skills, tools, culture and insights to our entire product range . We have also created a central performance engineering team, where we will drive shared tools, dashboarding capabilities, measurement frameworks, analytical capabilities and skills. We call this career focus ' percorr ' because we have found that the same deep insights that enable sophisticated performance measurement and design also enable teams to improve their harnesses and frameworks for correctness. Understanding not only the application, but the runtime, the compiler, and the system, all the way down to the CPU, gives an engineer the ability to think creatively and with insight about the right things to measure, and the right ways to verify correctness. We have found that performance engineers will often improve the deepest and trickiest areas of our test harnesses, and unblock their teams to test and measure previously 'dark' aspects of their work. We also have teams that work with every major silicon vendor and cloud, with a particular emphasis on performance optimisation of the entire stack for that architecture, CPU family or hypervisor. Our goal is to ensure that Ubuntu users can select whatever platform they want for their workloads and know they have access to the very best performance and efficiency across the entire stack from kernel to codec. If they wish, we will enable performance and correctness engineers to move between products every two years, so that they have the opportunity to raise the bar for performance in an array of products over time, and also that teams have the benefit of fresh eyes on their processes, thinking, harnesses, dashboards and code. Our performance and correctness leads are expected to be truly exceptional individuals, and also leaders who are confident setting expectations of change, sharing insights and skills, running initiatives and programs. There is no way to move a meaningful codebase without also moving the people behind it. This is a career path for perfectionists and precision artists. Whether you have a particular language focus - C, C++, Rust, Golang, Python, Java, Flutter-Dart or others - or a particular love of the kernel or hardware or CPU instruction set, whether you see yourself as driving perceived user experience through performance or optimising the efficiency of data centers to reduce carbon footprint, this process is the best way to find a role at Canonical that speaks to your precision, rigour, insight and drive.

Teams meet two to four times yearly in person, in interesting locations around the world, to align on strategy and execution. The company is founder-led, profitable, and growing. This is a general track for first-level engineering management positions at Canonical. We believe that open source is just starting to transform the tech sector and enterprise compute. Our goal is to make open source easier, more reliable, and more secure for deployment and development. We strive to be the provider of ‘most software to most companies’. To deliver on that ambition, our engineers are carefully selected from the applicants across the globe. We select for brilliance and motivation to take open source to the next level. Our engineering managers help teams achieve more than they realised they could, and feel proud of the result. We believe that Engineering Managers should be outstanding developers themselves. They should be completely at home reviewing a patch or a software design spec. They are trusted engineers who understand the importance of a whole-team effort in creating great products and who enjoy seeing colleagues develop. They should contribute code themselves to set the standard for coding, but know that the code they write is far less significant than their ability to shape the whole team’s direction, focus, and delivery. We grow management skills and train engineers who are interested in soft skills to be managers. A typical first-level software engineering team is based in a single time zone, such as EMEA or Americas, or APAC, with an Engineering Manager and a Senior Engineer dedicated to a single product, who work as a team to shape the roadmap, technical strategy, code, documentation, and community engagement. They are both capable of coding, and are both leaders comfortable assigning work and maintaining expectations of delivery. They will both be expected to take management training at Canonical so they speak the same language when it comes to team behaviours, habits, routines, norms, and standards, but they focus on different sides of the problem. An Engineering Manager is responsible for line management and career guidance. The ability to develop engineering talent, to represent your team and product from a technical perspective, and to drive collaboration with other teams and customers are all critical to success in this role. We have open manager roles across a wide range of engineering domains, including: Python and Golang C / C++ / Rust Data infrastructure HTML / CSS / JavaScript / Typescript / React Flutter Distro packaging and systems SAAS and web microservices Kernel Servers Graphics, Browser and Desktop Silicon enablement and embedded devices Product Security If your domain of expertise isn’t listed above, yet you feel it’s relevant to Canonical, then feel free to apply anyway.
