Senior Software Developer

The Senior Software Developer serves as a technical leader on an agile team supporting a portfolio of established Microsoft .NET applications and one legacy Classic ASP application. This is primarily a sustaining engineering role: keeping business-critical systems stable, secure, and well documented, delivering targeted enhancements, and mentoring developers across local, remote, and offshore Team Partners. We are looking for an experienced, dependable developer who takes pride in systems that run well and teams that run well. This role rewards steady execution and sound judgment more than it rewards greenfield development. What this role is (and what it isn’t):

• The application portfolio is mature and stable. Much of the work is maintenance, production support, defect resolution, and small-to-moderate enhancements. Large new builds are not on the near-term horizon.
• One of the applications is a legacy Classic ASP system. Supporting it is a real part of this job, not a footnote.
• Our long-term modernization strategy is still being defined. Whoever fills this role will have meaningful input into shaping it.
• Production support is handled during normal business hours. There is no after-hours on-call rotation., Technical Leadership
• Provide day-to-day technical direction for the team and serve as the primary point of escalation for complex issues.
• Mentor and develop team members, including offshore Team Partners, through pairing, code review, and knowledge sharing.
• Establish and uphold coding standards, review practices, and a clear definition of done.
• Coordinate work across local, remote, and offshore team members, including managing time zone overlaps and handoffs.
• Contribute feedback to IT leadership and product owners to help inform future technology direction.
