Puter (https://github.Com/HeyPuter/puter) is an open-source cloud operating system, a platform that makes it radically easier for developers to build, host, and deploy applications and websites: no complicated setup, no infrastructure headaches.Being open source is core to how we work. Our codebase is public, we build in the open, and we actively engage with community contributions. You'll be reviewing PRs from the community, discussing issues, and helping shape the project alongside people outside the company.We're just getting started: monetization tools, granular permission systems, instant CDN deployments that go live as you save, and much more are on the roadmap.The RoleWe're looking for a Senior Software Engineer to focus primarily on backend systems, though comfort working across the stack is a plus. You'll be working on a wide range of APIs and features that power our platform, everything from real-time communication layers to distributed storage to scaling infrastructure.This is an early-stage startup. The pace is fast and the work is fresh and exciting. You'll tackle compelling challenges across domains that don't typically live together. That also means priorities can shift quickly and schedules aren't always predictable. If you thrive with autonomy and like owning your work end-to-end, you'll do well here.We're a small team, so we need someone who can find their footing and run with things without a lot of hand-holding. We also want someone who speaks up, if something's broken or could be better,



say so. We're not looking for people who just go along with things. And as a senior engineer, we'd hope you'd help raise the bar for the team, whether that's through code reviews, mentoring, or just pushing us all to build better stuff.What We're Looking ForTechnical SkillsFamiliarity with web platform technologies: WebSockets, WebRTC, WebTransport, IndexedDB, Service Workers, etc.Experience building or working with real-time systemsExperience with cloud platforms such as AWS, Cloudflare, or AzureUnderstanding of scalable and distributed systems architectureKnowledge of various database and storage technologies and when to use them (MySQL, DynamoDB, Redis, etc.)Experience with performance profiling and optimization, and tools like OpenTelemetry, AWS X-Ray, Grafana, etc.Experience with ops, SRE, or reliability engineering is a plusOpen source contribution experience on GitHub is a plusWho You AreYou take ownership of your work and see things throughYou learn quickly and adapt as requirements evolveYou're comfortable with ambiguity and can make progress without perfect informationYou communicate openly about blockers, concerns, and ideas for improvementYou're excited by hard problems and novel technical challengesCompensation$150,000 - $200,000 + equity + benefitsPay is influenced by various considerations and can fluctuate according to position-specific qualifications, competencies, and work history#J-18808-Ljbffr
