Senior Software Engineer (Merchant Onboarding)

Join Tabs, a fast-growing fintech company, as a Senior Software Engineer on our Merchant Onboarding team. You'll be responsible for streamlining the onboarding experience, unlocking growth, and amplifying our internal teams. You'll work across real production systems, complex data flows, and product surfaces used by teams who need software they can trust. We value critical thinking, collaboration, and a passion for building meaningful systems.

• Participer à la conception et au développement de systèmes de production, de flux de données complexes et de surfaces de produits utilisés par les équipes.
• Travailler en étroite collaboration avec les équipes Produit et Design pour résoudre des problèmes de manière collaborative.
• Assumer la responsabilité de systèmes significatifs, façonner l'évolution de la plateforme et apprendre de pairs talentueux dans un environnement dynamique.
• Enjoy owning systems end-to-end, from first design doc to fixing production edge cases weeks later
• Can disagree respectfully, explain your reasoning, and change your mind when the data says you should
• We're optimizing for excellent engineers who are good teammates
• Are curious about domains you don't already understand, and are willing to sit with discomfort while you learn
• Care deeply about correctness and long-term maintainability
• Whether you're "frontend" or "backend" by title
• Whether you've worked in fintech before
• What we don't care about as much:
• If you've built scalable systems, shipped real software, and learned from breaking prod a time or two, we want to talk
• Exact years of experience
• Familiarity with modern backend languages and frameworks
• Experience building web applications or backend services in production
• Experience with modern frontend frameworks such as React, Vue, or similar
• Experience working with APIs and relational databases
• 5-8 years of professional software engineering experience
• If you want to build real systems with people who care deeply about their craft, we would love to hear from you. Engineers who thrive here like hard problems, clear ownership, and strong teams. If that sounds like you, apply!
