Senior Back End Engineer

Role Description

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
• 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.

• 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.
