Job description:

**About Kilvin** Kilvin is an AI-native software agency that builds custom internal tools for non-technical teams. We deliver everything through **our platform**: a shared workspace for our clients to access and interact with their software. We believe strongly in the principle of **personal software**: technology purpose-built for the individual, and that AI-enabled software generation provides the greatest opportunity to bring personal software to the masses. Founded by [Chris](https://www.linkedin.com/in/cschlaep/) and [Jorrie](https://www.linkedin.com/in/jorrie/) - MIT CS grads and former Googlers. **The role** We are able to deliver faster than traditional agencies in thanks to our proprietary build pipeline and hosted workspace platform that's been battle-tested in client deployments across healthcare, finance, and operations applications. We're now investing in the **next iteration of that platform**: transforming it into a self-serve tool for a more technical audience. As a Senior Platform Engineer, you'll own core pieces of that system. You'll work directly with our CTO and Head of Engineering on the infrastructure that turns "we need a tool for X" into a running, integrated, access-controlled application. This is a high-ownership role: small team, real users from day one, and decisions that shape the product for years. **What you'll work on** * **The app runtime and workspace** - how custom apps are deployed, isolated, and served to clients inside a single secure environment. * **The build & deploy pipeline** - the AI-assisted system that takes a user request from requirements to specs to software takes requirements to working software. * **Multi-tenancy and access control** - tenant isolation, fine-grained permissions (who can open which app and see which data), and the auth model underneath it. * **Integrations** - a framework for connecting client apps to the CRMs, spreadsheets, email, and databases they already rely on, so data moves cleanly between systems. * **Reliability & observability** - monitoring, performance, and the tooling that lets a small team run many production deployments with confidence. **What we're looking for** * Experience with LLM orchestration or AI-assisted code generation in production. * 3+ years building and operating production software, with meaningful time spent on platform, infrastructure, or backend systems. * Strong fundamentals in distributed systems, data modeling, and API design. * Experience with multi-tenancy, auth/permissions, or sandboxing. * Comfort owning systems end to end: you can design it, ship it, operate it, and debug it in production. * A bias toward shipping. You're energized by a fast build–test–iterate loop and real users, not by long specs. **Nice to have** * Experience at an early-stage startup or as an early/founding engineer. * Background in regulated domains (healthcare, finance) and the compliance that comes with them. * You've built developer-facing or internal platforms that other people built on top of. **Our stack** We care more about strong engineers who are comfortable with AI-assisted development workflows; if you've gone deep somewhere adjacent, we want to talk. * We work in **TypeScript** end to end, maintaining a single monorepo spanning frontend, backend, and CLI tooling. * Our frontend is **React**; the backend is **Node.js** services on **Express**, talking to **PostgreSQL** through **Prisma**. * Auth and sessions run on a modern auth library, and the whole platform is deployed to **AWS**, with infrastructure managed as code in **Terraform**. * Our build-and-deploy pipeline leans heavily on **modern LLM tooling** to turn requirements into working software. **Logistics** * **Location:** Remote within the US. We have a strong preference for candidates in or near **NYC, Denver, or Philadelphia** for periodic in-person collaboration. * **Compensation:** Competitive salary plus meaningful early-stage equity. We offer health benefits through a QSEHRA: a tax-free monthly reimbursement toward your health insurance premiums and qualified medical expenses. We're happy to discuss specifics early in the process.
