Job description

This is a senior-level backend engineering role (6+ years required) with a federal consulting firm, offering a solid blend of modern cloud-native technologies and stable government contract work.

Compensation analysis:

The $110,000–$140,000 range is slightly below market for a senior .NET engineer with Kubernetes and Azure expertise in private-sector tech (typical range: $130,000–$170,000+). However, federal contracting roles often trade peak salary for job stability, predictable hours, and strong benefits — a reasonable trade-off for many engineers.

• ASP.NET Core & C# at an enterprise scale — highly transferable and in consistent demand
• GraphQL API design — growing in adoption across both enterprise and startup ecosystems
• Kubernetes/AKS and Helm — cloud-native skills that command premium salaries
• Federal compliance (CUI handling, Public Trust) — a niche differentiator that opens doors to cleared/federal work

Green flags:

Remote-first, Agile delivery, mentorship opportunity, training & development benefit, and exposure to cloud modernization of legacy federal systems.

Yellow flags:

The Public Trust requirement adds a background investigation process (can take weeks to months). The tech stack is Microsoft-centric — excellent for .NET specialists but limiting for polyglot engineers. No mention of equity or performance bonuses, which is typical for GovCon.

This role suits a senior .NET engineer seeking stability, meaningful public-sector impact, and cloud-native growth without the volatility of startup environments.
