Software Engineer, Platform and Integrations

Luminate Bank is redefining what modern banking can be. In just five years under its current leadership, the company has grown from a $62 million community bank into a $500 million financial institution, the fastest-growing state-chartered bank, while building one of the fastest-growing mortgage platforms in the country.

The momentum has been extraordinary:

• Grew bank assets from $62 million to $500 million in five years- the fastest-growing state-chartered bank
• Ranked a 2026 Top Workplace in Minnesota by the Star Tribune and #1 among large companies in Colorado Top Workplaces 2026
• Named a 2026 Top Workplaces Culture Excellence winner in eight categories and a Top Workplace nationally in Financial Services
• Surpassed $4 billion in mortgage originations in 2025
• Ranked among the Top 30 Mortgage Lenders nationally by Scotsman Guide
• Maintain a 4.9-star average rating across 45,000+ customer reviews
• Recognized by Freddie Mac with two 2026 Home Possible RISE Awards® for Greatest Volume and Fastest Growth
• Honored by the Minnesota Mortgage Association as 2025 Leaders of the Year

But the story is bigger than growth metrics and awards. Luminate Bank is building a culture designed for ambitious, high-performing people who want to shape the future of banking. We move quickly, think boldly, and invest deeply in our people. Innovation, accountability, collaboration, and customer experience are at the center of everything we do.

What began as a rapidly growing lending and banking platform is now entering its next phase: building a nationally recognized financial brand that redefines how modern banking is experienced.

For leaders who want the opportunity to build, scale, and leave a lasting impact, this is a rare moment to join a company with startup energy, national momentum, and a long runway ahead.

Luminate Bank is hiring a Staff Software Engineer to design, build, secure, and run the proprietary applications and integrations that connect our banking and mortgage platforms. You'll ship priority business software hands-on—using AI coding agents such as Claude Code to accelerate delivery—while setting the team's standards for secure delivery, reliable operations, and responsible use of AI tools in a regulated environment where most of our applications handle nonpublic personal information (NPI).

This is an individual contributor role. You'll provide technical direction and coaching to a small team of engineers and specialists; people management stays with the EVP, Technology or a designated manager. Most of your time will be hands-on engineering, with protected time for design, mentoring, documentation, and cross-training. Early priorities include moving from Azure Dev Ops to Git Hub, improving the reliability of key integrations, and building applications that fill gaps in our vendor platforms.

• Design and build production applications, services, and extensions for priority banking and mortgage needs, working with business owners to define scope and acceptance criteria.
• Build and support integrations using REST APIs, webhooks, events, and scheduled batch exchanges. Evaluate vendor capabilities and find maintainable ways to close gaps between third-party software and how Luminate operates.
• Make integrations safe under failure with authentication, input validation, idempotency, bounded retries, rate limiting, and safe replay, and use reconciliation to confirm business outcomes.
• Own architecture and technical quality for assigned services, including API contracts, automated tests, and support documentation.

• Use the bank's approved AI coding agents (e.g., Claude Code) to speed up implementation, testing, and…
