Platform Engineer

Conduct
London, United Kingdom
On-site

Who this role is best for

Geared toward infrastructure-focused engineers comfortable with building platforms for AI systems, with a preference for candidates who have experience scaling systems at fast-growing startups and can work in a collaborative, high-velocity environment in London.

Best fit for

  • Candidates with experience scaling infrastructure at fast-growing startups or scale-ups
    — “Have owned infrastructure - networks, databases, deployments - through a period of real scale at a fast-growing startup or scale-up.”
  • Individuals who prioritize shipping practical solutions over theoretical perfect setups
    — “Solutions that solve the problem and ship fast, rather than the perfect setup on a six-month roadmap”

Things to consider

  • The role requires a commitment to work in London, though relocation support is available
    — “We're convinced diverse teams ship better products and especially encourage underrepresented groups in tech to reach out.”
  • Candidates must be comfortable with building and owning infrastructure rather than just maintaining it
    — “We look for exceptional talent, regardless where you spike. Experience level matters less than the quality of your thinking and the evidence of what you've shipped; building and scaling platforms with modern tooling, rather than just maintaining them.”

How to stand out

  • Emphasize your experience with infrastructure-as-code and multi-cloud integrations in your resume and interviews
    — “Azure, managed with Terraform: everything as code, with multi-cloud integrations for LLM providers across AWS, GCP and others”
  • Highlight your ability to make informed decisions on platform architecture and database choices
    — “Have informed, strong opinions on the big calls - like whether to stay on Postgres or move to something like Supabase or PlanetScale”
  • Demonstrate your understanding of AI-specific infrastructure needs like LLM gateways and agent sandboxes
    — “Understand how AI changes infrastructure - LLM gateways, caching, flaky providers, agent sandboxes, durable execution.”
  • Showcase your ability to create developer-friendly tools and abstractions that others want to use
    — “Build clean abstractions and paved paths that other engineers actually want to use”

About the role

Original posting from Conduct via Ashby

TL;DR: This is not a regular engineering job. We're looking for exceptional builders who help us design and ship systems that define how the world's largest companies operate in the age of AI.

WHY CONDUCT

The world's largest companies are slowed down by the software they run on. We're building the AI operating system that absorbs IT complexity and unlocks entirely new levels of speed, output, and ambition. We believe this is a generation-defining mission.

Major enterprises already trust us with their most critical systems, we just closed a $60M+ Series A from top-tier funds, and we're still early enough that what you build here defines the company.

We're a small, talent-dense team doing our life's work at Conduct - we value ownership, high velocity, and low-ego collaboration. If you bring that same drive, we will make sure this is the place you do yours too.

WHO WE HIRE

We are relentless builders, and we're looking for people who share that obsession with shipping to customers.

As our founding Platform Engineer, your role is to build and scale a reliable, resilient, observable, performant and secure platform that makes our product engineers faster. We care about outcomes: you should be excited by building the foundations that let us ship a killer product fast, not by hard infrastructure problems for their own sake (though you'll have plenty of those).

You'll stand out if you:

  • Have owned infrastructure - networks, databases, deployments - through a period of real scale at a fast-growing startup or scale-up.
  • Treat infrastructure as code by default (Terraform or similar) and stay on top of the latest platform tooling
  • Simple, well-reasoned system design. Solutions that solve the problem and ship fast, rather than the perfect setup on a six-month roadmap
  • Have informed, strong opinions on the big calls - like whether to stay on Postgres or move to something like Supabase or PlanetScale
  • Understand how AI changes infrastructure - LLM gateways, caching, flaky providers, agent sandboxes, durable execution. You don't need to be an AI researcher, but you've played with the tools and have a point of view
  • Build clean abstractions and paved paths that other engineers actually want to use

We look for exceptional talent, regardless where you spike. Experience level matters less than the quality of your thinking and the evidence of what you've shipped; building and scaling platforms with modern tooling, rather than just maintaining them.

We hire the best to join our team in London, wherever they come from (we sponsor visas and provide relocation support!). We're convinced diverse teams ship better products and especially encourage underrepresented groups in tech to reach out.

WHAT YOU'LL OWN

Everything that sits below the product code. Today that work is shared across the team; you'll own it, with the autonomy to set the direction, decide what matters most, as well as scope and prioritise work yourself with the backing of the broader engineering team. As our engineering team grows fast, every improvement you make compounds across everyone building Conduct.

  • Deployment: fully automated, repeatable deployments of the whole platform, so we can stand up new regions - starting with the US.
  • Enterprise-grade security: customer-provided encryption keys, network boundaries and tenant isolation that hold up to the scrutiny of the world's largest companies
  • Bringing core services in-house: running durable execution, vector search and agent sandboxes inside our own infrastructure rather than renting them as a service
  • Data: scaling and tuning our databases, and owning where our data layer goes next
  • Developer experience: a fast, reliable local setup, preview environments from any branch, and build tooling and CI that keep up with a growing team
  • Observability: end-to-end tracing, structured logging and alerting that product engineers can self-serve
  • AI infrastructure: our LLM gateway, model routing, cost monitoring and resilience to flaky providers

OUR STACK

Our stack prioritises what matters: shipping to customers—fast—without compromising on quality and engineering.

Fundamentals are more important to us than familiarity with any technology or tool: if you're strong, we're sure you'll pick it up fast.

Here's our setup:

  • Azure, managed with Terraform: everything as code, with multi-cloud integrations for LLM providers across AWS, GCP and others
  • Kotlin and TypeScript services in a containerised monorepo, with CI/CD on GitHub Actions
  • Temporal and PortKey: durable execution and enterprise-compliant LLM routing at the core of our platform
  • Postgres for our data layer, with TurboPuffer for vector search
  • Agent sandboxes running on Daytona and other providers
  • OpenTelemetry and Honeycomb for observability
