A Senior Software Engineer for React

Senior Frontend Engineer Level is a modern RMM platform built around real-time data, automation, and an uncompromising focus on UX. We're profitable, growing, and shipping fast with a small team. Our platform manages devices across thousands of organizations. We're hiring because there's more to build than one frontend developer can handle. You'll be the second UI developer on the product. The surface area is large, the problems are complex, and the pace is fast. You'll work on peer-to-peer remote control, a powerful automation engine, and an AI-powered virtual technician we're bringing to market this year. We need someone who can carry that weight, not someone looking for a place to settle in. What you'll work on Level isn't a CRUD app. Scale â— Our platform manages a distributed network of user devices. You'll build interfaces that surface real-time data across that network reliably and fast. Real-time remote control â— WebRTC peer-to-peer connections that let users manage devices with low latency across unpredictable networks. Automation â— A visual engine that lets IT teams build complex, multi-step workflows. The kind of UI that's easy to use and hard to build. AI virtual technician â— A new feature we're building this year. You'll help shape and ship the interface from the ground up. Everything else â— This is a small company. You'll touch dashboards, data visualization, forms, real-time updates, and things we haven't thought of yet. Who you are You have deep, senior-level JavaScript and frontend experience. You use AI tools extensively â— Codex, Claude, or whatever works â— and you've spent real time figuring out how to get the most out of them. You also know when the output is wrong and can fix it. AI makes experienced developers faster. It doesn't replace the experience. You're a builder. You want to shape the product, not just execute a list of tasks someone else defined. You don't need to be managed. You see what needs to happen and you make it happen. You've worked with TypeScript, React, Next.js, and GraphQL. If you haven't used all of them, you're the kind of person who picks things up fast because you understand the fundamentals. Why you might want this job The problems are genuinely hard â— real-time systems, peer-to-peer connections, complex UIs on top of a large, distributed device network. You'll have enormous ownership. There are no layers between you and the product. We're profitable and growing. This isn't a company burning through runway hoping for a miracle. Small team, no bureaucracy. When you ship something, it's in front of customers immediately. Why you might not We're a small team. There's no one to hand things off to and no one to share the load with when it's heavy. We move fast and expect you to keep up. If you're used to spending months on a single feature, this will feel different. You'll own the entire frontend surface area alongside one other developer. If you want to specialize in one corner, this isn't the role. You'll context-switch. A lot. You might fix a gnarly WebRTC bug in the morning and build a new dashboard view in the afternoon. We rely heavily on async communication. You need to write clearly and work effectively without waiting to be told what's next. Details Compensation: $180,000 USD Location: Fully remote. Level is based in the US. International candidates are welcome â— we require at least 5 hours of overlap with US Eastern time (9amâ-5pm ET). Benefits: Medical, dental, and vision insurance (US employees). Hardware, software, and books â— whatever you need to do your job. How to apply Apply at https://tally.so/r/ODAKrA Tell us why you're interested in Level and this role specifically. We value clear, thoughtful communication. For questions reach out to hiring@level.io.

About Brave Brave is on a mission to protect the human right to privacy online. Weâ've built a free web browser that blocks creepy ads and trackers by default, a private search engine with a truly independent index, a private ad network (opt-in!) that directly rewards you for your attention, and a browser-native AI integration focused on keeping private data private. And weâ're just getting started. Already 110 million people have switched to Brave for a faster, more private web. Millions more switch every month. The internet is a sea of ads, hackers, and echo chambers. Big Tech makes huge profits off our data, and tells us whatâ's true and whatâ's not. Brave is fighting back. Join us! The Browser AI team are building core browser features, and exploring new ideas about how the personal nature of the browser can help create the best AI experience for research and creative tasks. Brave allows the user to attach tabs, history, bookmarks and files to AI conversations. Brave also allows the user to experiment with AI joining in with its own web browsing. Weâ're looking for a new team member capable of iterating these ideas and creating beautiful user experiences for these features. UI engineers will often work with other engineers to create the end-to-end features, or develop the skills necessary to implement the entire feature themselves. Brave has an exciting UI engineering culture. We share knowledge and patterns across both teams and disciplines, overlapping closely with designers. We work with internal design systems, multiple UI frameworks, and make effective decisions on these features as a team. This role is at an exciting intersection between web UI, web browser internals, and AI possibilities. Brave is a start-up, and we have the ability to change plans quickly in response to new information or circumstances. This means that new needs can emerge on short notice, and projects are often re-mixed and adjusted in response to new input. Successful applicants will have the opportunity to influence those choices and other areas of the team. Many engineers in this role at Brave start from a frontend or full-stack background and grow into browser-level C++ feature work over time. Responsibilities will include: Implementing browser-integrated Web UI (e.g. AI conversations, browser settings, new tab page) using Typescript, JavaScript, HTML and CSS with React as well as other frameworks such as Web Components, Svelte and Lit Working with our product development team to collaborate on designs and specs and bring them to life on Brave's desktop and mobile browsers Integrating with custom browser APIs using Chromium's communications frameworks. Helping to customize the native UI provided by Chromium to add new product features and modify existing features. These UI elements include toolbars, modals, buttons, and more Delivering code which is well tested with high confidence Working alongside and learn from our experienced Chromium engineers - helping with peer reviews and helping improve our engineering processes Required experience: Strong skills building complex web apps with state management Deep knowledge of a Javascript UI framework such as React, Svelte, Vue, or native Web Components Proven expertise with CSS for building UI Commitment to various UI accessibility and localization techniques Understanding of performance impact and how both to measu
