Platform Engineer

📋 Job Overview

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.

🏢 About 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.

🎯 The Role

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).

✅ Key Responsibilities

• Own everything that sits below the product code, setting the direction and prioritizing work.
• Implement fully automated, repeatable deployments of the whole platform.
• Ensure enterprise-grade security with customer-provided encryption keys and tenant isolation.
• Bring core services in-house, running durable execution, vector search, and agent sandboxes.
• Scale and tune databases, owning the future direction of the data layer.
• Provide a fast, reliable local setup and build tooling that keeps up with a growing team.
• Implement end-to-end tracing, structured logging, and alerting for observability.
• Manage AI infrastructure, including LLM gateway, model routing, cost monitoring, and resilience to flaky providers.

📌 Required Qualifications

• 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.
• 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.
• Build clean abstractions and paved paths that other engineers actually want to use.

⭐ Desirable Experience

• Experience building and scaling platforms with modern tooling.
• Experience with Kotlin and TypeScript services in a containerised monorepo.
• Experience with Azure, managed with Terraform, and multi-cloud integrations.
• Experience with Temporal and PortKey for durable execution and LLM routing.
• Experience with Postgres, TurboPuffer, Daytona, OpenTelemetry, and Honeycomb.
