Senior Software Engineer, Product

**About the role** We're hiring a Senior Software Engineer to build and own features end\-to\-end across ProSpend's spend\-management platform. This is an AI\-native role: you'll steering coding agents, and owning the quality of what ships. You'll work in a small team with real ownership — close to the product, close to the decisions. We're looking for someone whose edge is judgement, not keystrokes: you turn ambiguous requirements into precise specs, delegate the first pass to agents, and bring the architecture, taste, and verification that turn agent output into reliable production software. **What you'll do** * Own features end\-to\-end — from spec to production. * Work agent\-first with AI tools. Turn Jira tickets and ambiguous requirements into clear, testable specifications; delegate first\-pass implementation to coding agents; review for architecture, correctness, and conventions; and own the code that ships. * Orchestrate, don't just prompt. Run multiple agent tasks in parallel and design the feedback loops — tests, evals, guardrails — that let agents work reliably without constant supervision. * Drive test automation and TDD with Playwright, JUnit, and Jest, with test cases authored and tracked in testing platform and wired into CI. * Hold the verification bar. AI output is fallible and you are accountable for what reaches production — you catch defects through disciplined review, strong typing, and automated checks. * Lift the team. Set conventions, write the specs and context that make both agents and teammates effective. **What we're looking for** * Bachelor’s degree or equivalent practical experience. * 5 years of experience programming in Java and Spring. * 3 years of experience programming in JS framework (Vue or React). * 1 years of experience testing, maintaining, or launching software products, and 1 year of experience with software design and architecture. * 1 years of experience with Generative AI Agents. * Solid understanding of Object\-Oriented Programming (OOP) and related design patterns. * Fluent with AI coding agents (Claude Code, Gemini, or Codex) in real production work — not demos. You can decompose a problem, write a precise spec, delegate to agents, and verify the result. * Strong code\-reading and review skills. You assess architecture, correctness, and maintainability quickly — in an AI\-native team, reading and reviewing matter as much as writing. * Test\-automation discipline. You write and maintain meaningful tests (Playwright / JUnit / Jest) and treat them as the contract that agent\-generated code must satisfy. * Ownership and comfort with ambiguity. You take a vague problem all the way to a shipped, reliable solution. * Clear written communication. **Bonus points** * Background in financial technology, enterprise SaaS, or business process automation. * Native mobile (iOS / Android). * QASE in practice or Newman/Postman API testing. * CI/CD pipeline design (Bitbucket Pipelines, GitHub Actions) and observability. * Designing agent workflows, evals, or reusable prompt/context patterns at team scale. * Security \& compliance awareness (ISO 27001 / data governance) Pay: $120,000\.00 – $150,000\.00 per year Benefits: * Free drinks * Parental leave * Salary packaging * Work from home Education: * Bachelor Degree (Preferred) Work Authorisation: * Australia (Preferred) Work Location: Hybrid remote in North Sydney NSW 2060
