Working closely with product owners, business stakeholders, and fellow developers, you will influence technical direction and drive continuous improvement. This fully remote opportunity is suited to an experienced developer who enjoys combining hands-on engineering, technical leadership, and mentoring. Accountabilities

You will lead application development throughout the software lifecycle, combining hands-on technical expertise with AI-assisted engineering practices and architectural guidance. Your responsibilities will include:

• Lead the application development lifecycle, including requirements analysis, solution design, development, testing, code reviews, and ongoing support.

• Design, build, and maintain .NET web applications, REST APIs, and integrations in line with established engineering standards.

• Develop solutions using cloud-based and service-oriented architectures, connecting business-critical systems such as CRM, ERP, inventory, and monitoring platforms.

• Investigate and resolve production issues using application logs, telemetry, databases, and AI-assisted analysis.

• Document technical fixes, maintain operational runbooks, improve application performance, address technical debt, and support continuous integration.

• Translate Jira stories into clear, testable acceptance criteria covering expected behavior, edge cases, and failure scenarios.

• Direct AI coding agents, including Claude Code, to prepare technical plans, generate code and tests, and open pull requests for review.

• Critically assess AI-generated technical plans, code, and tests for accuracy, security, scope, quality, and potential regressions.

• Maintain traceability between requirements, technical plans, testing, and deployment, including documentation for change approval requests.

• Evaluate test results in system integration and staging environments and determine whether changes are ready for production.

• Improve shared AI agent prompts, skills, and rules while coaching developers on effective AI use and appropriate human oversight.

• Help establish technical and architectural direction for applications and systems.

• Collaborate with product owners and business stakeholders to identify solutions and deliver business value.

• Lead peer reviews and quality assurance activities, participate in Agile/Scrum ceremonies, and recommend process improvements.

• Mentor developers and share technical knowledge across engineering, support, and cross-functional teams.
