Platform Engineer - AI

Overview

Full-stack engineering role building the modern platform for HWA International's trust accounting software, using agentic tooling to analyze existing behavior and deliver C#/.NET services, a web front end, and the AWS infrastructure they run on.

What you'll do

• Build the modern platform across the stack: write features, services, and fixes in C# and .NET, and the web front end that sits on them, against the architecture and patterns the team has set.
• Own the infrastructure for what you deliver: define and maintain AWS environments as code, including networking, managed databases, and services, so every environment is reproducible and version controlled.
• Own delivery and observability: build and run CI/CD pipelines, staged rollout, and feature flags, plus monitoring, logging, and alerting.
• Use agentic tooling to analyze established application and database logic, then produce a clear written specification of the behavior that has to be preserved.
• Relocate business logic, including rules inside the database, into maintainable, tested application code, and build data migration paths and test harnesses that show the modern platform's calculations match the existing ones.
• Verify what the tools give you: read and confirm the code behind any agent's account of existing behavior, and write characterization tests before behavior changes.
• Own the work in production: take part in incident response, communicate clearly while an issue is open, and follow through to root cause and a durable fix.

What you'll need

• Several years of professional C# and .NET development, with production code you can describe and defend.
• Strong relational database skills: schema design, query tuning, and correct transaction and error handling.
• Demonstrated ability to work out what unfamiliar code does, including code in a language or platform you have not used before, with a repeatable method for doing it safely.
• Deep, hands-on fluency with agentic coding tools (such as Claude Code, GitHub Copilot, or Cursor) as your primary way of working on real production code, from day one.
• Working knowledge of a modern web framework.
• Working knowledge of AWS, infrastructure as code, networking, managed databases, and containers.
• Working knowledge of CI/CD with automated testing and zero-downtime deployment, plus production monitoring and alerting.
• Git and GitHub, with trunk-based development and short-lived branches.
• Comfort owning quality on a system that cannot fail quietly: disciplined testing, observability, and careful, staged rollout.
• Clear written and spoken English.

Nice to have

• PostgreSQL experience.
• React with TypeScript.
• Azure experience.
• Experience in financial services or another regulated, high-stakes domain; trust accounting, wealth management, or fiduciary services is a strong plus.
• Experience modernizing an established business application onto a cloud-native stack.
• AWS certification or equivalent depth in security, identity, and cost management on AWS.
• Building software under SOC 1 / SOC 2 or comparable regulated-environment controls.
