Principal Engineer, Software

ABS Group Digital Solutions is seeking a Principal Software Engineer to help build the next-generation Fleet Management System (FMS). This role will lead hands-on application engineering for modern web and SaaS workflows, working with product, UX, Nautical Systems subject matter experts, Advantage architects, platform engineering, data, and AI teams. The Principal Software Engineer will own the technical quality of assigned product areas from design and implementation through testing, deployment, and production support.

This is an AI-enabled engineering leadership role, not simply a full-stack development position. The successful candidate will turn validated workflows and architecture decisions into clear engineering tasks; use approved AI development tools and coding agents where they add value; and remain accountable for the security, correctness, maintainability, and operability of the resulting software. The role calls for a senior engineer who can mentor others, make pragmatic tradeoffs, and build reusable patterns without losing sight of customer outcomes.

What You Will Do:

• Lead technical design and hands-on development of FMS application features, including role-based user interfaces, APIs, business services, and integrations.
• Work with product managers, UX designers, legacy-system SMEs, and customers to translate operational workflows and prototype feedback into buildable designs and acceptance criteria.
• Guide engineers on application architecture, service boundaries, data access patterns, and reuse of shared platform capabilities; document consequential design decisions.
• Break work into well-scoped tasks and direct AI-assisted engineering workflows, including code generation, refactoring, test creation, and documentation, while applying human review and verification to every production change.
• Establish and model engineering practices for code review, automated unit and integration testing, secure development, CI/CD, and maintainable software delivery.
• Integrate application features with approved AI/ML or LLM-based services where there is a validated user need, including appropriate authorization, monitoring, and human oversight.
• Partner with platform engineering and SRE to make applications observable, performant, resilient, deployable, and supportable in production.
• Contribute to integration and migration designs so new capabilities can coexist with legacy systems and customer data can transition safely as releases mature.
• Mentor engineers and contractors, review designs and pull requests, resolve complex technical issues, and raise the quality of delivery across the team.
• Participate in release readiness, production troubleshooting, root-cause analysis, and continuous improvement of the AI-enabled software development lifecycle.
• Comply with applicable ABS security, quality, Health, Safety, and Environmental requirements and other internal policies.
