Senior Platform Engineer
At Permutable AI, 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.
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
What We're Looking For
- 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.
