## Description

At Permutable, we're building real-time AI systems that transform large volumes of global news, market and proprietary data into market intelligence and systematic signals for financial institutions.

We're evolving our technology towards a more real-time, event-driven and agent-driven architecture and are looking for a Senior Platform Engineer to take ownership of the platform and infrastructure behind it.

As a small, ambitious team, you'll work directly with our founder and engineering team and have significant influence over how our next-generation architecture is designed and built.

**What You'll Do**

**Design & Scale our Platform:** Build and evolve highly available production infrastructure across AWS, Kubernetes/EKS, ECS, Docker, RDS/PostgreSQL and S3.

**Build Event-Driven Architecture:** Help move our architecture from scheduled pipelines towards real-time, event-driven services using messaging, queues, asynchronous processing and distributed systems.

**Build Infrastructure for AI Agents:** Develop the infrastructure required to run increasingly agent-driven AI workflows reliably in production, including state management, task execution, model routing, retries and observability

**Support AI Infrastructure:** Work closely with our AI engineers supporting production NLP, LLM and quantitative model workloads, including our in-house GPU infrastructure.

**Automate Infrastructure:** Build and manage Infrastructure-as-Code using Pulumi and automate deployments through GitHub Actions.

**Own Reliability & Observability:** Build monitoring, logging, tracing and alerting across our data, model, service and agent infrastructure.

## Requirements

**7+ years of professional experience:** in Platform Engineering, Infrastructure, SRE, DevOps or distributed backend engineering.

**Strong AWS experience**, ideally including EKS/ECS, RDS/PostgreSQL, S3 and Lambda.

**Distributed Systems Experience:** Strong understanding of event-driven architectures, messaging, asynchronous processing and distributed workflows.

**Infrastructure-as-Code:** Experience with Pulumi, Terraform or equivalent.

**CI/CD & DevOps:** Experience with GitHub Actions or equivalent, automated testing, deployments, monitoring and production operations.

**Strong Engineering Fundamentals:** Python, Linux, networking, databases and cloud infrastructure.

**Production Ownership:** Comfortable diagnosing difficult production problems and taking responsibility for critical infrastructure.

**Startup Mindset:** Proactive, resourceful and comfortable taking ownership in a fast-moving engineering environment.

**Bonus**: with Apache Airflow, real-time data platforms, AI/ML infrastructure, LLM agents, GPU infrastructure or financial-market systems.

## Benefits

**Real Ownership:** Take significant ownership of our production architecture and infrastructure.

**Build the Next Generation:** Help move our platform towards real-time, event-driven and agent-driven architecture.

**AI at Scale :** Work with LLMs, AI agents, quantitative models and large volumes of continuously arriving data.

**Technical Influence:** Have a meaningful say in architecture and technology decisions.

**Real Production Impact:** Your work will quickly reach production and support institutional financial clients.

**An Ambitious, Collaborative Culture:** Join a close-knit team with the pace, openness and shared sense of purpose of a high-growth start-up. We work together from our Vauxhall hub and make time for regular team socials and company offsites.

**Hybrid Flexibility:** Spend three or more days each week in our Vauxhall hub, with flexibility to work remotely for the remainder.
