London, Vauxhall | Hybrid: at least three days in the office each week
Permutable builds market intelligence and systematic signals for financial institutions from continuously arriving global news, market and proprietary data.
We’re hiring a Senior Platform Engineer to take responsibility for the infrastructure behind those systems and help move our platform from scheduled pipelines towards real-time, event-driven processing.
You’ll work directly with our founder and engineering team, making architecture decisions and building the systems that put them into production. The work spans AWS infrastructure, Python services, distributed workflows and reliability, with increasing demands from our NLP, LLM and quantitative model workloads.
What you’ll work on
- Develop our production platform. Build and operate reliable infrastructure across AWS, using EKS/ECS, Docker, RDS/PostgreSQL and S3.
- Move processing towards real time. Design services and workflows using queues, messaging and asynchronous processing, with clear approaches to retries, failure recovery and state management.
- Build infrastructure for AI workflows. Support task execution, model routing and agent workflows that need to run reliably in production.
- Improve deployment and reliability. Manage infrastructure through Pulumi, automate deployments with GitHub Actions, and strengthen monitoring, logging, tracing and alerting.
- Support demanding model workloads. Work with our AI engineers on production NLP, LLM and quantitative systems, including our in-house GPU 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 you’ll bring
- Substantial hands-on experience in platform engineering, SRE, infrastructure or distributed backend engineering, including responsibility for production systems.
- Strong AWS experience: you have designed, deployed and operated services, and can explain the trade-offs behind your decisions.
- Strong Python engineering skills, including building and maintaining production services or data-processing systems.
- Experience with event-driven architectures, messaging, queues and distributed workflows.
- Practical experience with containers, infrastructure-as-code and CI/CD. Terraform or equivalent experience is welcome alongside Pulumi.
- A solid understanding of Linux, networking, databases and observability, with the ability to diagnose difficult production problems.
- The judgement to prioritise work, make architecture decisions and follow them through in a small engineering team.
Get help with your application
Your very own career expert that helps elevate your application to the next level.
Experience with Airflow, real-time data platforms, AI/ML infrastructure, LLM agents, GPUs or financial-market systems would be useful. You do not need experience with every tool in our stack.
Why join Permutable?
- Influence the architecture. Help decide how our platform evolves as we move towards real-time processing and more complex AI workflows.
- Stay close to the engineering. Work directly with the founder and engineers, with responsibility from design through deployment.
- See your work used in production. Build infrastructure supporting market intelligence and signals for institutional financial clients.
- Work across data and AI systems. Tackle the reliability and scaling challenges created by continuously arriving data and production model workloads.
We work together in our Vauxhall office at least three days each week.
If you want to help us build the systems that turn the world’s unfolding events into intelligence financial institutions can act on, and want a bigger say in what gets built next, we want to hear from you.
