About the role

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

Degree in a related technical field: Computer science, software engineering or similar.

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 and databases.

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

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 hub and make time for regular team socials and company offsites.

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