Advanced knowledge of relational databases, including schema design, query optimization, and performance tuning.

Experience operating in Agile development environments.

Strong communication skills with the ability to collaborate across technical and non-technical stakeholders.

Demonstrated ability to mentor engineers and lead through influence rather than authority. Experience in Property & Casualty, Specialty, or Commercial Insurance.

This is a senior individual contributor role with significant influence over architectural decisions, engineering standards, and long-term technical strategy. This role is well-suited for someone who values architectural ownership, autonomy, and meaningful technical impact, and who thrives in a collaborative, fast-paced environment.

Compensation $80-96/hr

Exact compensation may vary based on skills, experience, and education.

Benefit packages for this role begin on the first day of employment and include medical, dental, and vision insurance, HSA/FSA/DCFSA options, 401(k) with employer match, and paid sick leave and/or other paid time off as required by applicable law.
