This is a rare opportunity to build the backbone of a whole new set of personal financial health products. You will set the technical bar for the team, guide system design decisions, and drive the reliability and accuracy that our users depend on to manage their financial lives. Working closely with product and engineering partners, you will operate in a fast-paced environment where sound architectural judgment and the ability to move quickly without sacrificing precision are essential. Our ideal candidate is passionate about solving complex technical challenges, eager to shape strategic direction, and motivated to lead a team building critical infrastructure from the ground up.

What You’ll Do

• Translate product requirements into robust technical solutions, recommend alternative approaches and lead engineering efforts to meet ambitious targets
• Lead a multidisciplinary team and manage the team’s tech refinements and productivity
• Design and implement reliable systems and applications in the context of a fully distributed micro-services architecture
• Build and maintain integrations with 3rd-party vendors and partners
• Design and implement highly available RESTful APIs supporting our internal admin portals
• Focus on creating reusable code and libraries that can be shared across teams, fostering collaboration and ensuring scalability for future projects
• Enforce observability best practices, leveraging tools like logging, metrics and alerting systems
• Create and maintain detailed technical documentation for all solutions, including architecture designs, APIs, workflows, and system configurations
• Continuously monitor Rain systems and applications for opportunities to maximize performance and scalability
• Effective cross-team communication and collaboration to align priorities, clarify requirements, identify dependencies, and ensure seamless coordination throughout the software development lifecycle

Who You Are

• You have 7+ years of professional experience, with at least 2+ years in a formal or informal leadership role

• You understand the trade-offs between consistency and availability in distributed environments
• You have a strong ability to take ownership of projects, driving initiatives from concept to completion, while proactively identifying challenges and solutions
• You have excellent cross-functional collaboration and communication skills
• You’re familiar with complex large scale distributed systems

Required Technical Qualifications

• Expert-level proficiency in Go (Golang) and/or Python
• Deep expertise in SQL (PostgreSQL), specifically regarding transaction isolation levels, locking strategies, and schema migrations at scale
• Strong experience with Kafka for building resilient, asynchronous workflows
• Proven experience at building reliable and scalable user-facing applications
• Advanced knowledge of AWS (ECS, EKS, RDS) and container orchestration using Docker/Kubernetes
• Experience building or improving CI/CD pipelines (GitHub Actions/GitLab CI) and a "you build it, you run it" mentality toward infrastructure-as-code
