Senior Software Engineer

Headquarters: Remote

Why this role matters right now

RETR is a bootstrapped, profitable B2B SaaS company. We're growing fast with a team of twelve. No investors, no burn, no VC-driven headcount ramp. Just customers who pay, expand, and stay.

We're building the "Carfax for mortgage and real estate." RETR is the data intelligence layer that mortgage professionals use to find and win real estate agent referral partnerships.

This is the third engineering hire on a small team. What you build ships. What you own affects revenue that same month, not the fiscal year.

What you'll do

• Design, develop, and maintain scalable ASP.NET Core applications and REST APIs across a layered (WebUI → Services → Repositories → NHibernate → SQL Server) architecture
• Collaborate with product managers, designers, and engineers to define requirements and technical specifications
• Lead architecture discussions and contribute to decisions on scalability, performance, and system design
• Build and maintain background jobs with Hangfire, integrations with Stripe, Twilio, SendGrid, and Azure services
• Troubleshoot and resolve complex technical issues in production and development environments
• Participate in Agile development
• Stay current on emerging technologies and evaluate their potential impact on the platform

The team

Three engineers total. You'll report to our Director of Engineering. He reports to our CTO, who is an engineer himself. That's the org.

Everyone ships. Everyone owns.

The stack

• Backend. ASP.NET Core, C#, REST APIs, layered architecture
• Data. SQL Server with NHibernate ORM
• Frontend. Razor/MVC, jQuery, Bootstrap
• Infrastructure. Azure (Blob Storage, Key Vault, SignalR), Hangfire for background jobs
• Integrations. Stripe, Twilio, SendGrid

What we're looking for

• 5+ years of professional experience with C# and .NET (Core / .NET 5+)
• Strong understanding of RESTful API design, layered architecture patterns, and ORM frameworks (NHibernate, EF Core, or similar)
• Solid SQL Server experience — complex queries, schema design, and performance tuning
• Comfortable working across the stack: backend services, Razor/MVC views, and JavaScript (jQuery/Bootstrap)
• Experience with Azure services (Blob Storage, Key Vault, SignalR) or equivalent cloud platforms
• Strong source control practices (Git), code review, and DevOps experience
• A creative problem solver with strong listening, logic, and critical thinking skills
• Team player with a passion for helping others succeed and a commitment to doing the right thing

Bonus. Experience with authentication patterns (JWT, cookie auth, SAML2, OpenID Connect). Mobile app development experience.

How we operate

Three philosophies we run by:

• Give more than you get.
• Lead with value.
• Do the right thing.

Five values behind them: Honesty. Integrity. Fairness. Accountability. Excellence.

You'll love this job if you already operate this way. If you don't, we're not the right fit for you.

Beyond that, you'll thrive here if you're a problem solver who prefers new problems to familiar formulas, comfortable in a small team that moves fast and wears many hats, and someone who ships.

What we offer

• $150,000-$170,000 base salary. National band, no geo-adjustment
• Fully remote, US-based
• Company-paid medical at 100% of your individual premium
• Dental, vision, life, short-term and long-term disability employer-provided
• 401(k) with match: 100% of your first 1% plus 50% of your next 5%
• 25 days PTO plus 13 paid holidays, including Christmas Eve and the day after Thanksgiving
• $100 weekly meal stipend, $100 monthly wellness stipend
• Full home office setup: laptop, monitors, camera, peripherals provided

What we don't offer

• Big-tech RSUs. We're bootstrapped. No stock grants.
• Bureaucracy. We're small and we like it that way.
• Layers between you and the work. You'll report to our Director of Engineering. He reports to our CTO, who is an engineer. That's the org.
