Position Description

We are looking for a Principal Architect to execute on the long-term technical direction of Tenna’s platform. As a Principal Architect, you’ll operate across teams to design scalable systems, guide architectural decisions, and ensure we’re building for both current needs and future growth. You’ll establish standards, lead design reviews, and ensure a high bar for technical quality across the organization, while providing hands-on guidance to solve complex challenges. Reporting to the CTO, you’ll partner closely with engineering leadership to ensure designs translate cleanly into what gets built and that those designs reflect real world constraints. You’ll play a central role in improving how reliably and efficiently we deliver software. We need a world class doer for this role, someone who can listen to a vision and personally drive the execution to make it a reality.

Responsibilities

• Own the execution of the Executive Team's technical strategy, turning high-level goals into actionable milestones and scalable system designs.
• Lead by example by personally building prototypes, core libraries, and foundational projects that set the standard for how the rest of the team builds.
• Set and enforce technical standards, ensuring every design choice handles failure modes, scalability, and performance in our production environment.
• Run a rigorous design review process that prioritizes backward compatibility and solid verification for our data-heavy systems.
• Evolve our microservices (Node.js/EKS/AWS), focused on reducing technical debt and making the system run more efficiently as we scale.
• Partner with Product and Engineering to make sure requirements are crystal clear and that what actually gets built stays true to the original vision.
• Master the data lifecycle, from IoT ingestion to storage and processing, building the foundations that our teams will eventually own.
• Roll up your sleeves to implement observability and monitoring standards, ensuring our platform hits the highest possible bar for uptime.

Qualifications

• 12+ years of professional software engineering experience.
• 4+ years of experience in an architectural leadership role (Principal Engineer, Staff Engineer, or equivalent) where you owned technical standards and design quality across multiple engineering teams.
• Experience turning high-level concepts into clear, documented patterns and designs that teams can implement independently—not just designing systems yourself, but enabling others to build them well.
• Deep expertise in distributed systems and microservices architecture, including operating and evolving a mature microservices environment (not just greenfield design).
• Strong hands-on experience with JavaScript and Node.js in service-based architectures. Our backend is built on Node.js microservices communicating via RabbitMQ and HTTP, running on AWS (EKS, Aurora PostgreSQL). You should be comfortable and opinionated in this stack, including API design, service boundaries, and asynchronous communication patterns.
• Strong data architecture experience, including designing systems that handle high-volume, real-time data (e.g., IoT or event-driven systems), and making tradeoffs across storage, processing, and access patterns
• Experience improving system reliability and performance at scale, including observability, monitoring, and fault tolerance.
• Demonstrated ability to influence across teams, driving alignment without relying solely on authority.
• Strong communication skills, with the ability to work effectively with both technical and non-technical stakeholders.
• Bachelor’s or Master’s degree in computer science or a related field, or equivalent industry experience.
