Our award-winning program helps employees navigate critical financial decisions from budgeting and benefits elections to equity compensation, home buying, and retirement so they can feel confident about their money and focused at work. Today, we're proud to serve some of the largest companies in the world.

We're building LearnLux with intention. We move quickly, operate with a high bar for quality, and value people who take ownership of their work. If you're energized by solving new problems, taking accountability, and pushing yourself to do your best work every day, you'll find this a rewarding environment.

We're a venture-backed company that has raised a series B and is supported by experienced investors and long-term partners. We're a growth-focused business building for scale, and we're excited by the opportunities and challenges that come with that journey.

At LearnLux, you will build a product that changes lives. Our mission is to empower people to take control of their financial future, whether that means getting out of debt, buying their first home, or preparing for retirement. As a Senior Software Engineer, you'll contribute directly to this mission by designing and building scalable backend systems that power our enterprise-grade SaaS product.

In this role, you'll lead and execute projects to tackle the complex technical challenges that come with scaling an enterprise platform. This includes distributed systems, cloud infrastructure, data architecture and pipelines, and AI-enabled features. You will play a critical role in delivering reliable, secure, and scalable systems while partnering closely with your team to execute against product and technical priorities.

We are a small, agile engineering team, and this role is hands-on. You'll be expected to operate effectively in a fast-moving startup environment, balancing execution, ambiguity, and evolving priorities. You'll spend the majority of your time building and shipping high-quality systems while collaborating closely with engineers, product managers, and data partners. You'll contribute to system design, improve engineering practices, and help drive projects forward with a strong sense of ownership. If you're excited by building impactful systems, working across the stack, and contributing to the future of financial wellness, we'd love to meet you.

This role is based in Denver, Colorado. Remote candidates will be evaluated on a case-by-case basis.

• Design and work with data systems, including SQL databases, pipelines, and data warehouses, to support product and operational needs.
• Run parallel AI-assisted coding sessions, continuously refining plans while shipping across multiple threads of work in real time.
• Develop and maintain cloud infrastructure for reliability and performance, primarily on GCP (with AWS experience welcomed).
• Apply strong engineering fundamentals to ensure systems are secure, reliable, compliant, and scalable.
• Work with infrastructure-as-code tools such as Pulumi (preferred) or Terraform to maintain consistent and scalable environments.
• Collaborate with product, design, and data teams to translate requirements into well-scoped technical solutions.
• Drive engineering efficiency through automation, including the use of AI-driven or agentic systems to improve developer workflows, operations, and internal tooling.
• Support global performance, reliability, and operational excellence.
• Contribute to documentation and knowledge sharing across the engineering team.

• Backend engineering experience, including ownership of scalable production systems in a SaaS environment.

• Experience in financial technology, regulated, or compliance-heavy enterprise SaaS environments.

• Thrive in fast-moving environments and enjoy building in moments of change. We operate with urgency, and roles, priorities, and approaches evolve as we grow.
• Like wearing multiple hats and helping define the path forward. At LearnLux, roles evolve as we grow, and employees often help create clarity, structure, and direction where it didn't previously exist.
• Take initiative and don't wait to be asked. You see problems as opportunities and are comfortable stepping in to move work forward.
• Are energized by ambiguity and willing to make decisions with imperfect information. We learn quickly by doing, and pace is a competitive advantage for us.
• Enjoy being hands-on and owning work end to end. While strategic thinking matters, execution, follow-through, and accountability are what drive impact here.
• Are motivated by high standards and continuous improvement. As we hit new milestones, we intentionally raise the bar on quality, ownership, and outcomes.
• Value clear, frequent communication and collaboration. As a remote team, staying aligned through proactive communication is core to how we operate.
