Full Job Description

Senior .NET Developer – Mission Feature Delivery (AI-Enabled)

IvoryCloud is hiring a Senior .NET Developer to drive new feature development for a high-visibility federal mission system. This is a build-forward role focused on delivering new capabilities that advance our client’s core mission. You will design and ship robust new functionality on a mature enterprise platform, and you will use AI tools fluently to accelerate how you solution, prototype, and deliver. We are looking for engineers who can apply AI as a force multiplier in their own work.

Requirements

U.S. Citizenship is required and non-negotiable
2 days a week in the Rockville, MD office are required and non-negotiable.
Active Public Trust highly preferred.
Ability to pass multiple background and employment checks - federal and local.
Bachelor’s degree Technology, Business, or Related Field

What You’ll Do

Design, develop, unit test, and peer review new features that expand the platform’s mission capabilities, from concept through production release.
Define the technical approach and accurately estimate effort for new functionality, enhancements, and change requests.
Use AI tools to solution faster — accelerating design exploration, prototyping, code generation, test scaffolding, documentation, and troubleshooting. (You will use AI; you will not be building AI/ML models.)
Build scalable, secure web applications using ASP.NET, C#, SQL, and Angular.
Partner with Business Analysts and QA to fully understand requirements and deliver against them.
Collaborate with the development team and federal technical stakeholders to plan and execute feature delivery.
Participate in code reviews and apply secure, defensive coding practices throughout.
Stay current on tools and techniques — including AI-assisted development — that improve delivery speed and quality.

Required Qualifications

U.S. Citizenship — non-negotiable.
Active Public Trust clearance — non-negotiable.
2 days per week onsite in Rockville, MD — required and non-negotiable.
Ability to pass federal and local background and employment checks.
Bachelor’s degree in Computer Science or a related field.
8+ years of professional ASP.NET / C# back-end development with SQL databases.
8+ years of professional Angular, HTML, CSS, and JavaScript front-end development.
Experience with .NET Core / modern .NET (8+).
Proven track record delivering new functionality in complex, workflow-driven enterprise systems.

AI Solutioning Skills (Required)

We expect you to work AI-fluently. The following are about using AI to deliver better and faster — not about engineering AI systems:

Hands-on use of AI code assistants (e.g., GitHub Copilot, Claude, AskSage, TabNine) in day-to-day development.
Ability to apply AI tools effectively across the delivery lifecycle — design, prototyping, code, testing, and documentation.
Sound judgment about where AI accelerates work and where human review and secure-coding discipline must govern the output.

Preferred Qualifications

Experience delivering on federal programs and working with government technical stakeholders.
Familiarity with Azure (App Services, Functions, Key Vault) and cloud-native delivery.
Strong grounding in OOP, SOLID, RESTful APIs, microservices, Git, and CI/CD.
Secure coding fluency: input validation (SQL injection, XSS), RBAC, MFA, OAuth/JWT, logging, and error handling.
Azure certifications (e.g., AI-102, Azure Architect) are a plus.
Proficiency across the stack: T-SQL, TypeScript, Node.js, EF, LINQ, Bootstrap, Webpack.

About IvoryCloud

IvoryCloud is a purpose-driven enterprise. We come to work to achieve for our customers, master new skills, and take ownership in growing those around us. You’re a fit if you are:

Driven by team and personal excellence, and committed to becoming a subject-matter expert wherever you’re applied.
A flexible thinker who solves problems with both linear and non-linear approaches.
Relentlessly focused on exceeding customer expectations.
Committed to teammate development, growth, and success.
Consultative by nature and never satisfied with the status quo — always looking to improve.

Benefits

Competitive salary with performance-based bonus opportunities.
Single and family health insurance, including dental.
Short- and long-term disability.
Matching 401(k).
Competitive paid time off.
Training and certification reimbursement.
Mentorship program and team-building activities.

Pay: $110,000–$130,000 per year, commensurate with experience

Pay: $110,000.00 - $140,000.00 per year

Benefits:

401(k) matching
Dental insurance
Flexible schedule
Health insurance
Life insurance
Paid time off
Referral program
Retirement plan
Vision insurance

Application Question(s):

This role requires U.S. citizenship. Please type 'citizen' if you meet this requirement.
Do you meet the hybrid requirements of 2 days a week in Rockville, MD?
Do you hold an active Public Trust clearance or higher? (not required)
