Senior Backend Software Engineer, Cloud Platform - UK

Unified Identity Securing Classic and AI Infrastructure

Teleport, the AI Infrastructure Identity Company, prepares organizations for an AI future by establishing a unified identity layer for infrastructure, with humans, machines, workloads, and AI agents secured cryptographically with a hardware root of trust rather than vulnerable credentials. By replacing fragmented identity and access management systems with Infrastructure Identity, Teleport scales zero trust across cloud and on-prem environments, eliminating the complexity and risk created by identity fragmentation and credential sprawl. Teleport protects infrastructure from identity attacks, accelerates engineering by reducing infrastructure complexity, and secures non-deterministic agentic workflows. Headquartered in Oakland, CA, Teleport operates globally, with industry-leading customers such as Nasdaq, IBM, Doordash, and Elastic.

Our Vision

Today's computing environments have too much complexity, too many network boundaries, and too little trust. Complexity slows engineers down and leads to human errors. Complex systems can’t be secure despite the red tape of bureaucracy. We make trusted computing simple. This gives engineers the freedom to move and build a better future.

Why Teleport

Teleport addresses the overlooked intersection between cybersecurity and infrastructure—an area companies have historically tried to manage through a fragmented mix of tools like PAM, network-centric controls, and fragmented secrets management. This approach was already inefficient, but it fundamentally breaks down in the era of AI.

AI changes the landscape in three critical ways. First, non-human, machine, and AI identities now outnumber human ones, driving massive secrets sprawl while worsening anonymity. Second, anonymity is incompatible with AI workloads: these systems are inherently non-deterministic, operate across many services and environments, and therefore require strong identity, continuous trust, and end-to-end visibility to function safely and correctly. Third, the non-deterministic nature of AI makes reliability and scalability non-negotiable—systems must be resilient, observable, and with access control guardrails, because failures and unexpected behavior cannot be handled with static controls or manual intervention.

Solving this problem requires a fundamentally different approach: a unified identity layer that spans machines, workloads, humans, and agents. Identity becomes the security control plane that replaces network location and long-lived secrets as the basis of trust. Ephemeral privileges are critical in this model—privileges must be granted just-in-time, limited to the task at hand, and automatically expire, dramatically reducing blast radius in systems where behavior cannot be fully predicted. Finally, real-time intelligence is essential: in fast-moving, AI-driven environments, access decisions must continuously adapt to context, behavior, and system state, rather than relying on static policies defined in advance.

Teleport addresses the growing gap between today’s cyber and infrastructure security posture and what modern, AI-driven systems actually require. As AI systems proliferate, attack surfaces and pathways multiply, giving adversaries unprecedented leverage. The result is an inflection point: without re-anchoring security and infrastructure around identity, real-time trust, and ephemeral privileges, the volume and impact of security breaches will only accelerate.

Get to use (and know) Teleport through our unique interview process

At Teleport, we do things a bit differently. And when we say we only hire top talent, we actually mean it. Because of this, our interview process is different too - and we’re proud of it. We let your work do the talking. We don’t go in for six rounds of interviews, live whiteboard or live-coding. We don’t hire people that can talk a good game. We only want the best. And for that, we need to see what you can do, in your own time, in your own way. For real.

But interviews are a two-way street. Through the project, you’ll get a real taste of life at Teleport, including:

• We’re flexible - you’ll have plenty of time to complete your project, if life gets in the way, that’s ok. We can - work around you.

• We give you autonomy - you’ll have the space and freedom to figure things out, make decisions, and problem-solve.

• We’re collaborative - Got questions?

• We have answers. You’ll have support from your team - the one you’ll be working with day in day out if you’re successful in getting the role.

• We progress careers - During the project, see how much you learn. That’s what working at Teleport is like. We like learning, on the job. All-the-time.

• We can move fast (if you can) - two weeks sound like a long time? No problem? Early submissions are fine, and we’ll keep the process moving.

Think you’ve got what it takes? We’d love to see it! Unconvinced? We can guarantee three things:

• It’ll challenge you.

• You'll learn a lot.

• If you love the process, you'll love working at Teleport.
