LearnLux - Staff Software Engineer - Architecture and Cloud Scale

• Lead the architectural design and incremental execution of LearnLux’s transition from single-tenancy to multi-tenancy in an enterprise SaaS environment. • Design and evolve cloud infrastructure for global scale, reliability, and data isolation, primarily on GCP (with AWS experience welcomed). • Own and improve our infrastructure-as-code approach, using Pulumi (preferred) or Terraform to ensure environments are repeatable, visible, and scalable. • Connect backend services, infrastructure, and data platforms into a cohesive, well-documented system architecture. • Partner closely with engineers, product, and data to translate strategic architectural goals into a prioritized and executable roadmap. • Build and maintain backend services using Node.js and Python, contributing hands-on to critical systems. • Collaborate with data workflows and platforms, including BigQuery and Airflow, ensuring backend systems scale alongside a growing data platform and data lake. • Drive engineering efficiency through automation, including the use of AI-driven or agentic systems to improve developer workflows, operations, and internal tooling. • Mentor and support other engineers, enabling them to ramp quickly and contribute meaningfully. • Uphold global performance, reliability, and operational excellence, leading by example. • Foster clear communication and thoughtful decision-making across backend, frontend, data, and infrastructure domains. • You should bring • Staff-level backend engineering experience, defined by scope and impact rather than years. • Proven experience designing and evolving large-scale, distributed, enterprise SaaS systems. • Hands-on experience leading or executing major architectural transitions (e.g., multi-tenancy, global scale, platform re-architecture). • Strong backend development experience with Node.js and/or Python. • Deep experience with cloud infrastructure, GCP preferred (AWS experience acceptable). • Experience building systems with security and compliance as first-class concerns in enterprise SaaS and global environments. • Experience working with data platforms and pipelines, including data warehousing, Airflow, and SQL/NoSQL databases. • Demonstrated experience using AI-driven or agentic automation to improve engineering systems, workflows, or organizational efficiency (e.g., automating operational processes, developer workflows, infrastructure management, or internal tooling). • Ability to thoughtfully identify where AI and automation create real leverage and to implement those systems pragmatically in production. • Ability to operate independently, lead through influence, and collaborate effectively across the stack • Demonstrated ability to mentor engineers and raise the overall effectiveness of an engineering team. • Strong communication skills, especially around architectural tradeoffs and technical decision-making. • It would be great if you also • Experience scaling teams or platforms through rapid growth phases. • Prior experience in financial technology, regulated, or compliance-heavy enterprise SaaS environments. • 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.
