• Systems & Data Mindset: Strong understanding of event-driven architectures and how core transactional systems feed analytical data engineering pipelines
• Fullstack Development: Ability to work across the stack comfortably, fully owning a product or feature
• Frontend – React.js, TypeScript, JavaScript (ES6+), and Expo (React Native) – Expertise with these is necessary
• Backend – Laravel (PHP) – Some experience is ideal, but not a necessity as long as you have demonstrable expertise building performant backend systems at scale
• Databases – PostgreSQL
• Infrastructure – AWS
• Collaboration & Communication: Exceptional communication skills. Clair is a fast-paced, highly collaborative environment. Whether on calls or in writing, we value clarity of communication and precision in what we say very highly

What the job involves

• At Clair, we are building technology that transforms how people access their pay. As a Senior Software Engineer on the Core Products team, your job extends well beyond converting tickets into pull requests
• We are looking for an engineer who operates like a Product Manager: someone who takes full ownership of the feature lifecycle, obsessively measures post-launch business outcomes, and designs systems with downstream impacts—like data pipelines and analytics—in mind
• You will lead the adoption of AI-native engineering practices across the team, leveraging state-of-the-art models, building autonomous agents, and embedding agentic workflows into both our core product architecture and internal development processes
• We operate at the intersection of fintech, embedded finance, and real-time payroll systems—building products that handle millions of transactions with sub-second performance. Your work will directly enable millions of hourly workers to access financial freedom
• End-to-End Product Ownership: Partner directly with design, product, and data teams to define technical strategy, question assumptions, and evaluate product trade-offs before writing a line of code
• Build with AI & Agents: Architect and deploy features utilizing AI models and autonomous agentic workflows. Drive the integration of modern AI tools to accelerate team velocity and enhance user experience
• System-Wide Architecture: Design resilient systems considering latency, scale, downstream data consumers, and telemetry, ensuring data pipelines receive clean, actionable events
• Measure Business Impact: Own features after launch. Instrument key metrics, monitor performance dashboards, investigate post-release gaps, and iterate based on real user behavior and business outcomes
