Now Hiring: Site Reliability Engineer (Node.js)

Do you want to join a rapidly growing learning technology company on a mission to change how people grow, train, and upskill at work?

Their platform powers engaging learning experiences for thousands of users across the globe — and they need a Site Reliability Engineer (SRE) to help keep everything running smoothly, securely, and at scale.

This is your chance to join a team where engineering and operations go hand-in-hand, and where you'll directly impact the reliability of a platform that truly matters.

Why This Role is Exciting

• You’ll work in a Node.js-first environment where product and platform teams collaborate closely.
• You’ll own core infrastructure and DevOps processes, from CI/CD to observability.
• You’ll be part of a team that encourages experimentation, autonomy, and continuous improvement.
• You'll help shape the SRE function at a high-impact stage of growth.

What You’ll Be Doing

• Build and improve CI/CD pipelines (GitHub Actions) that keep development smooth and fast
• Maintain and scale infrastructure on AWS, including ECS, S3, RDS, and CloudFront
• Improve observability using tools like Datadog and CloudWatch — and act on what you find
• Automate key workflows around deployment, testing, scaling, and failure recovery
• Collaborate with engineers to build scalable, secure, and resilient services in Node.js
• Take part in incident response, post-mortems, and ongoing performance tuning
• Work with tools like Terraform and Docker to keep infrastructure consistent and version-controlled

The Tech You'll Be Using

• Languages: Node.js (TypeScript), SQL
• CI/CD: GitHub Actions

What They're Looking For

• Strong experience working in production Node.js environments
• Hands-on with AWS services and container orchestration (ECS, Docker)
• Skilled at building and maintaining CI/CD pipelines
• Experience with observability, monitoring, and incident management
• Working knowledge of infrastructure-as-code (Terraform, CloudFormation)
• A collaborative, proactive mindset with strong communication skills

What You’ll Get

• A collaborative, mission-driven culture that values technical excellence and personal growth
• Real ownership and the chance to shape the future of a platform used by top companies
• Learning budget and support for professional development
• Competitive salary, benefits, and flexible working options
• A supportive team that genuinely values wellbeing, diversity, and inclusion
