Our engineering hubs in EMEA and LATAM are full of talented professionals delivering business success and digital improvement across application development, software architecture, CI/CD, business intelligence, QA automation, and new technology integrations.
We are looking for a Senior SRE with AI/ML platform experience to work on a project with a leading provider of software for the fitness industry.
The project:
Our teammates are talented people that come from a variety of backgrounds. We’re committed to building an inclusive culture based on trust and innovation.
You will be part of a distributed team focused on revolutionising the fitness industry with digital solutions in over 60 countries. The team is building a platform that saves time, increases retention, and ultimately, helps studio and gym owners become more successful.

- Design, build, and maintain AWS infrastructure using best-practice architecture and service selection.
- Drive reliability improvements through strong observability practices (metrics, logs, tracing, alerting).
- Lead capacity planning efforts, asking the right scaling questions, and proactively preventing bottlenecks.
- Implement and enforce Infrastructure as Code standards, ensuring all infrastructure is fully managed through Terraform
- Support deployment and operations of AI-enabled platform components (e.g., proxies, vector stores, inference services)
- Collaborate with designers, developers, product managers, and testers to transform ideas into unique, human experiences for fitness entrepreneurs.
What you will bring:
- More than 8 years of experience in Site Reliability Engineering or Infrastructure-focused DevOps roles.
- Deep understanding of distributed systems and how to operate them reliably in production.
- Expertise across core AWS services (EC2, Load Balancers, ECS, VPC, IAM, S3, Secrets Manager, and related foundational services)
- Strong experience with Infrastructure as Code with Terraform.
- Hands-on experience with AI/ML platform infrastructure (Bedrock, inference tooling, vector stores).
- Observability-first approach, with hands-on experience implementing monitoring and tracing systems.
- Strong production mindset: you think in terms of resilience, failure modes, and operational safety.
- Solid capacity planning skills and experience scaling platforms responsibly.
- Solid knowledge of SRE best practices and industry standards.
Nice to have:
- Familiarity with AI-focused AWS services (SageMaker, Managed Apache Airflow)
- Exposure to running open-source LLM inference workloads in production (e.g., Ollama, vLLM, llama.cpp)
- Desire to contribute to the wider community through collaboration, coaching, and mentoring of other technologists.
What we offer:
- 100% Remote.
