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 over $35M to date 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.

The Role

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 Staff Full Stack Product Engineer, you’ll help set the technical direction for a platform that’s revolutionizing how people access fiduciary financial guidance, and build the foundation that helps users around the world work toward their financial goals.

In this role, you’ll own the architecture for the next generation of our member experience, a major evolution to how people engage with LearnLux. You’ll define a cohesive full-stack strategy across frontend architecture, data architecture, backend integrations, and agentic automation. Then you’ll break that strategy into clear, well-sequenced pieces the team can deliver against with confidence. Beyond any single initiative, you’ll make high-leverage architectural decisions that shape LearnLux’s long-term technical direction and create durable foundations for products we haven’t imagined yet.

We’re a small, fast-moving team where your voice carries. You’ll be a close technical partner to engineering leadership, represent engineering in strategic planning, and help connect our technical investments directly to company goals. You’ll work with Product, Design, Sales, and other teams to shape what we build, why we build it, and how it comes to life, and you’ll raise the bar for how the whole team builds. If you’re excited to define the technical foundation of a product people rely on for their financial lives, build AI into it end to end, and do it on a team that values initiative, curiosity, and craftsmanship, we’d love to meet you.

This role reports into the Product Engineering Manager. This role is based in Denver, Colorado. Remote candidates will be evaluated on a case-by-case basis.

What you’ll do

• Own the end-to-end architecture for our next-generation member experience, and break the full-stack strategy into phased work the team can run with.
• Solve real user problems at scale, turning data-driven insights into novel product solutions and measuring whether they actually move outcomes.
• Design and ship AI-powered features across the stack, and set the patterns, guardrails, and evals that let the team build with AI reliably.
• Lead multi-quarter, company-critical initiatives from concept to delivery, resolving cross-team dependencies before they slow anyone down.
• Turn ambiguous business problems into coherent technical strategies, partnering with Product, Design, and leadership to shape the roadmap.
• Set architectural direction across our React, TypeScript, Node.js, Python, and serverless GCP stack, staying hands-on by directing agents that build, test, and ship.
• Make high-leverage architectural calls that balance short-term delivery with long-term platform health, and get ahead of systemic risks early.
• Champion agentic development workflows and drive their adoption, multiplying the leverage of the whole engineering team, not just your own.
• Develop senior engineers into technical leaders through mentorship, pairing, and modeling ownership and systems thinking.
• Own reliability by design, and step in to lead resolution when complex issues arise, making our systems more resilient along the way.

You should bring

• Staff-level experience, defined by scope and impact rather than years, owning architecture and technical direction for multi-team and multi-quarter initiatives.
• Deep experience shipping GenAI features in user-facing products, including evals, observability, cost, and reliability, and a drive to push what’s possible with AI.
• Expert full-stack experience across React, TypeScript, and Node.js and/or Python, including systems and API design and relational and non-relational data models.
• A track record of simplifying code and architecture to reduce complexity and maintenance cost.
• Proven ability to decompose large, loosely defined initiatives into phased roadmaps and executable plans a team can deliver against.
• Fluency with agentic development workflows and a history of driving their adoption, including structuring the context teammates and AI agents need to succeed.
• Experience maturing agent harnesses: the agent loop, tool access, memory and context management, guardrails, sub-agent orchestration, and extensions like hooks, skills, and MCP.
• Strong product and business judgment: you connect technical decisions to customer experience, cost, and revenue, and weigh build vs. buy vs. partner strategically.
• Hands-on experience designing scalable, secure systems on major cloud platforms (GCP, AWS, Azure, etc.). Experience with sensitive financial or personal data is a plus.
• Strong communication skills, especially around architectural tradeoffs and technical decision-making.
• A force multiplier who has elevated engineering culture and standards, and who invests in growing the engineers around them.

LearnLux is a fit for you if you

• 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.
