Senior Full-Stack Software Developer (.Net,#C)

About Liberty Fox Technologies

Liberty Fox Technologies is a consulting firm that partners with clients to maintain, rebuild, and develop enterprise applications — primarily in the healthcare space. We’re not a staff augmentation company — our teams include project managers, QA, business analysts, and technical leads who work together through the entire project lifecycle. Our core stack centers around .NET and Blazor, though we also deliver solutions in React, Angular, and other modern frameworks based on clients needs. (Must be experienced and comfortable working with .NET/C#)

About the Role

We’re looking for a Senior Full-Stack Software Developer who thrives in a collaborative, fast-paced consulting environment. This role is for someone who wants to take ownership of their work, engage deeply with both the team and clients, and help lead projects to successful outcomes.

You’ll work alongside other team members to scope and estimate projects, guide junior developers, and deliver high-quality applications using agile methodologies. You’ll also be responsible for keeping projects on track — ensuring estimates are accurate, tickets are up to date, and communication flows smoothly.

If you’re looking for a role where you can make a real impact, lead by example, and stay close to modern technology, this is the place for you. We’re a small, passionate team that values accountability, craftsmanship, and directly impact clients’ success, not just push tickets in a queue.
