Founding Engineer

Longwave is on a mission to transform MSPs (outsourced IT firms) into AI solutions providers. Every small and midsize business is using AI, and they’ll rely on their MSP to help them adopt AI safely and confidently. We help MSPs evolve for the AI era, remain indispensable to their clients, and build new recurring revenue streams.

• IT firms are the trusted advisor: Small businesses already rely on their IT firm for security and compliance. Now they’re asking for help with AI.
• Legacy vendors weren’t built for AI: Their tools are clunky and built for large enterprises. AI is everywhere now. We’re reimagining what access controls, data loss protection, and IT services look like for the businesses that need them most.
• AI is expanding rapidly into SMBs: IT firms need to monitor AI usage and set the rules. This is where they deliver value: visible security, ongoing policy, and risk management. We’re solving a real and urgent problem for our customers.

We’re hiring a founding engineer to help us build and scale. We have a solid foundation, fast growth, and a long list of customer demands. You’ll work directly with the founders and own full-stack problems from day one.

• Real scale: Deployments are doubling every month. You’ll build systems that grow to millions of endpoints.
• Expert generalist: Our policies are enforced on every device, so the product lives everywhere. You’ll work across our full-stack app, backend, browser extension, and Rust desktop agent.
• Good intuition and taste: Clean, extensible code lets us keep saying yes to big customer problems.
• Ship constantly: Extreme focus on shipping user-facing products and features.
• Tech stack: Next.js, TypeScript, Postgres, ClickHouse, Rust (Windows and macOS agent), and a TypeScript browser extension.

• 3+ years of software engineering experience.
• Independent: you ship quickly with minimal direction and product guidance.
• Strong engineering fundamentals and the ability to learn quickly. Rust and Windows experience not required.
• Obsession with security and reliability. Longwave is SOC 2 compliant and “just works.” We have a high quality bar, take pride in our work, and never ship AI slop.
• Customer focus. Our customers are IT professionals who expect production-grade software from day one. You’ll meet them regularly to make sure we’re building what they need.
• US work authorization required.

We offer a competitive benefits package, including comprehensive medical and dental coverage, commuter benefits, and a generous vacation policy. We believe great work comes from people who are well taken care of, and we’re committed to making Longwave a great place to build your career.

Longwave is on a mission to transform MSPs (outsourced IT firms) into AI solutions providers. Our insight is that MSPs will be the final mile of distribution for AI products to small and mid-sized businesses in every industry.

We raised our pre-seed round in 2026 from Comma Capital, Dria Ventures, and Top Down Ventures. Our co-founders (CEO, CTO) bring big-tech experience and a hypergrowth mentality to the world of MSPs.
