Tech Lead (Senior Software Engineer)

About the role

Join our team as a Tech Lead, where you'll own the technical direction of the Signals engineering team and drive the next phase of the product forward. This hands-on leadership role involves setting the technical vision, making architecture decisions, and writing code, while also unblocking your team and working directly with product, data, and revenue stakeholders. You'll lead a small, high-output team of engineers and QA, and be accountable for the quality, reliability, and velocity of everything the Signals team ships. Key missions: Assumer la direction technique de l'équipe d'ingénierie Signals, en prenant des décisions d'architecture et en écrivant du code.. Diriger une petite équipe d'ingénieurs et d'assurance qualité, en définissant les priorités, en débloquant le travail et en conduisant l'exécution.. Travailler directement avec les parties prenantes pour traduire les problèmes commerciaux en une feuille de route technique. Profile: - The ideal candidate has led engineering teams before, treats AI coding tools as core infrastructure for how they work, and has a track record of shipping products that customers love — not just features that meet specs - You have strong system design instincts — you know how to architect systems, define clean interfaces, and make decisions that hold up as complexity grows - You are stack-flexible: comfortable working across Python, TypeScript/React, and cloud infrastructure (AWS, Databricks). You learn new tools fast and don't let unfamiliar tech slow you down - You lead by example — your team follows your standard because they see you hold yourself to it first - You have 6+ years of hands-on software development experience with at least 2 years in a technical leadership role — leading teams, making architecture decisions, and owning delivery - You hold a Bachelor's or Master's degree in Computer Science, STEM, or a related technical discipline - You have an AI-native workflow — you don't just use AI tools, you've fundamentally changed how you and your team work because of them - You have shipped and maintained customer-facing SaaS products — you understand what it takes to build software that real users depend on - You are responsive and reliable — you take ownership of production systems and communicate proactively, especially under pressure - You can context-switch between writing code, unblocking a teammate, and presenting a technical tradeoff to a non-technical stakeholder — all in the same day
