Ad fatigue is killing engagement, but we’re fixing it. Thanks (thanks.co) is building the world’s first customer-first ad network, an advertising platform that delights consumers instead of just targeting them.
We’re seeking a Principal Engineer to help design and scale this groundbreaking platform. This is a senior technical leadership role: you’ll work closely with our founders, CTO, and product/engineering teams to shape technical strategy, solve complex challenges, and mentor others while remaining deeply hands-on.

• Shape system architecture and guide technical strategy – contribute to long-term design decisions, advocate for scalability, reliability, and security across our stack, and help drive pragmatic tradeoffs aligned with business needs.
• Lead complex initiatives – break down ambiguous problems, scope complex projects, and shepherd them from idea to production.
• Raise the technical bar – champion engineering excellence in design, code quality, testing, performance, and developer productivity.
• Mentor and influence – provide technical guidance to senior engineers, foster growth across the team, and help establish a strong engineering culture.
• Lead by example – design and build critical features and infrastructure across the stack, setting examples of best practices in action.
• Cross-functional leadership – partner closely with product, design, and leadership to shape roadmaps, evaluate trade-offs, and ensure technical alignment with company vision.
• Scale operations – help define processes, observability, and reliability practices that keep our systems performant and resilient as we grow.
