About The Role

Our direct client is hiring Software Engineers to be part of the team that builds and operates the internal platforms that keep the business running—enterprise applications, workflow automation, and systems integrations that support factory, supply chain, and corporate operations.

This role is primarily backend, with optional opportunities to contribute to frontend work (React) depending on team needs and your strengths.

Improve code quality through strong testing practices, code reviews, and thoughtful refactoring
Optionally contribute to web UI features in React when projects call for it

Minimum Qualifications

5+ years of professional software engineering experience delivering production systems
Strong backend fundamentals: API design, service architecture, data modeling, and debugging
Professional experience with at least one of: Golang, Java, or C# (.NET)
Experience working across the delivery lifecycle (design → build → test → deploy → operate)
Strong ownership mindset and clear communication

Preferred Qualifications

Experience building internal tools or enterprise software in integration-heavy environments
Knowledge of distributed systems patterns (microservices, event-driven architectures)
Comfort with CI/CD pipelines and automated testing (unit + integration)
Observability experience (structured logging, metrics, tracing) and production troubleshooting
React experience (TypeScript preferred) for candidates who want to contribute full-stack occasionally.
