This role will design, build, deploy, and support secure full-stack applications, APIs, integrations, automations, and internal tools while establishing practical engineering best practices. This role will also establish proper GitHub practices, CI/CD pipelines, and AI-assisted development guardrails that help teams deliver quickly without sacrificing quality, security, or maintainability.
Essential Duties and Responsibilities: Design, build, test, deploy, and support full-stack web applications, REST APIs, integrations, automations, and internal tools, from database schema through user interface. Translate business requirements into technical designs that balance performance, security, maintainability, scalability, and cost. Own GitHub repositories and engineering standards, including branching, pull requests, releases, protected branches, required reviews, CODEOWNERS, documentation, and least-privilege access. Build and maintain CI/CD workflows using GitHub Actions or similar tools, including automated testing, code-quality checks, security and dependency scanning, deployment approvals, validation, and rollback. Create reusable application templates, components, and standards that accelerate secure and consistent delivery.

Before you apply

Applying takes about a minute. These four things decide how fast it moves after that.

Your profile is current

It's what we read first. Occupations, seniority and locations matter more than a long history.

Two examples you can talk through

Not a portfolio — just two pieces of work where you can explain the decisions and what you'd change.

A number in mind

What you're on now and what would make you move. We negotiate better when we know both.

Your notice period

Employers plan around it, and it's the question that stalls offers most often.

Once you apply, someone reads it and calls you before anything reaches the employer — usually within two working days.
