ZERORISK

Full-stack Engineer

• Triage and investigate production issues — querying logs, correlating events across services, and identifying root causes rather than surface symptoms.
• Navigate both Angular front end and Java back end codebases to trace issues end to end, from a reported UI behaviour through to service logic and data layer.
• Implement targeted code fixes for confirmed bugs, ensuring all changes are covered by tests, submitted via pull request, and reviewed before merging.
• Escalate fixes that require architectural change or touch high-risk areas of the codebase to the Senior Engineer before proceeding.
• Produce clear post-incident summaries covering what happened, root cause, resolution, and steps being taken to prevent recurrence.
• Build and maintain internal tools that help the team investigate and manage recurring production issues more efficiently.
• Identify manual or repetitive investigation steps that are candidates for tooling and prioritise building solutions that save meaningful time across incidents.
• Maintain existing tooling to ensure it remains accurate and useful as the platform evolves.
• Proactively research and evaluate new tools and technologies that could improve operational efficiency.
• Build and maintain a library of debugging playbooks and how-to guides covering common production issues.
• Update playbooks after every significant incident to incorporate new learnings.
• Identify gaps in the playbook library and prioritise filling them based on incident frequency and impact.

Infrastructure Engineer

• Design, build, and maintain a robust, automated API testing infrastructure that can be spun up reproducible across local, CI, and production-mirror environments.
• Develop and maintain a shared library of reusable test utilities, fixtures, helpers, and patterns for use across engineering teams.
• Own the containerization strategy for test environments using Docker (and related tooling), ensuring tests run consistently and reliably regardless of where they execute.
• Integrate the testing infrastructure into existing CI/CD pipelines, including test reporting, alerting, and failure triage workflows.
• Continuously evaluate and introduce new tools, frameworks, and practices that improve the reliability, speed, or coverage of the infrastructure.
• Build and maintain a suite of automated integration tests that validate the behavior of third-party and external API-based tools the organisation depends on.
• Design monitoring and alerting strategies that detect regressions or unexpected changes in external API behavior as early as possible.
• Collaborate with internal teams to understand integration requirements and translate them into automated, continuously-running test scenarios.
