Member of Technical Staff (Platform Leaning)

No two days will be the same at Tessl! You'll have a high level of autonomy and be empowered to make decisions based on what you believe will help you deliver the most success. Here's an insight into just a few of the things you would be doing:

What we're looking for

We're looking for someone who is as excited as we are to be part of a dynamic team that is shaping the future of AI and software development. We're committed to building a diverse team and strongly encourage applications from people of all backgrounds, identities, and experiences.

Must-haves

• Proven experience as a Software Engineer (TypeScript/Node preferred): you care about code modularity, structure and aesthetics, and you're equally comfortable contributing to a mature codebase with strict CI criteria or hacking up a quick prototype to prove an assumption

• A genuine pull towards platform and infrastructure work, backed by hands-on experience: you've deployed and operated real systems (Kubernetes, cloud environments, infrastructure-as-code, CI/CD), and when the chance came to go deeper, you took it, whether that was owning platform or DevOps work in a previous role or picking up the infrastructure tasks nobody else wanted

• Solid systems and networking fundamentals: DNS, TLS, VPCs, firewalls; you can reason and debug below the application layer with confidence

• Demonstrated use of AI coding tools and agents to accelerate your own work, and excitement about experimenting with new AI approaches to transform how engineering is done

• Comfortable with fast-paced, high-autonomy environments: you turn loose requirements into plans and shipped work without waiting to be told

Nice-to-haves

• You self-host things for fun: a homelab, your own services, a Kubernetes cluster nobody asked you to run

• Production AWS/EKS experience, or hands-on work with private connectivity, VPNs, or multi-region architectures

• Experience producing infrastructure evidence for certifications such as ISO 27001 or SOC 2

You've thrived in an early-stage startup before
