[Hiring] Senior Full Stack Software Engineer @North Mill Equipment Fi

Role Description

The Senior Software Engineer role is designed for someone who thrives at the intersection of product thinking, technical ownership, and cloud-native engineering.

• Implement monitoring, logging, and alerting high-availability systems.
• Collaborate closely with product manager and designers in a product-driven model.
• Build fintech systems with attention to data integrity, auditability, and regulatory considerations.
• Troubleshoot and resolve production issues across application and infrastructure layers.
• Mentor engineers through code reviews and technical guidance.

• Experience with relational and/or NoSQL databases.
• Proficiency with Git and CI/CD workflows.
• Ability to take ownership of complex systems and mentor other engineers.
• AWS certification is not required.

Skills/Attributes

• Cross functional collaboration - ability to partner with product managers and designers.
• Problem-solving and debugging – Strong analytical skills with the ability to diagnose issues across application, infrastructure, and data layers.
• Adaptability in product-driven environment – Comfort working iteratively, responding to customer feedback, and balancing speed with long-term technical quality.
• Infrastructure as code (Terraform, CloudFormation, or CDK).
• Fintech, lending, underwriting, or payment experience.
