Senior Software Engineer (Java, AWS ECS, DynamoDB, Lambda, Terraform, Docker)

About the role

We’re looking for a Senior Software Engineer to help enhance and maintain the platform that powers our ScriptRunner Cloud products.

This is a hands-on role where you’ll play a key part in shaping the technology that supports thousands of teams around the world.

You’ll work in a collaborative, agile environment, continuously delivering improvements through CI/CD pipelines, tackling complex challenges, and designing scalable, high-performing solutions.

As a senior member of the team, you’ll also have a voice in our technical direction, engineering practices, and process improvements — helping to ensure that our platform remains robust, reliable, and future-ready.

What you'll be doing

• Design and evolve the platform: set up build pipelines, select web/server technologies, design hosting architectures, and organise repositories for scale and clarity.
• Ship continuously: create automated build and deployment plans, contribute to CI/CD best practices, and pair program/review code in an Agile workflow.
• Build the right solutions: research and document approaches within Atlassian Connect and Forge constraints; design services and architectures to meet customer needs at scale.
• Go serverless where it fits: build and test serverless applications; define stacks with Terraform, AWS SAM, or CDK.
• Keep it reliable: run, monitor, and debug services; configure meaningful alerts; analyse logs/metrics for performance and behaviour; evaluate systems for operational reliability.
• Migrate without drama: move high-traffic systems to new designs with zero downtime.
• Own the ops: participate in on-call/incident response, lead post-incident learnings, and drive platform improvements

What we're looking for

• Proven experience building and operating large-scale systems on AWS (ECS).
  
  Strong background in high-availability, fault-tolerant, distributed systems.
  
  Fluency in Java and Spring Boot.
  
  Excellent organisational, prioritisation, and communication skills.

A few nice to haves

• Hands-on CI/CD experience.
• Understanding of serverless and microservices architectures with extensible REST APIs.
• Familiarity with Terraform, SAM/CDK.
• Experience with Atlassian Connect and/or Forge.
• A track record of creative problem-solving and helping teammates grow.
