Senior Software Engineer

About the role

We are seeking a Senior Software Engineer to join our team as a high-ownership, product-minded contributor. In this role, you will take end-to-end responsibility for key features and platform components within our full-stack ecosystem: Ruby on Rails (backend), React (web), and Flutter (mobile).

Key Responsibilities

• Build and maintain features across our full stack (Ruby on Rails, React, Flutter), taking end-to-end ownership from initial design through production.
• Operate with high autonomy, driving architectural decisions and navigating ambiguity to solve impactful engineering challenges.
• Elevate our engineering culture by setting high standards, mentoring teammates, and simplifying processes to help the team move faster as we scale.
• Prioritize pragmatic simplicity, ensuring we build only what is necessary to validate assumptions and deliver value, while resisting complexity that hinders agility.
• Ensure the reliability and performance of our critical systems by taking ownership of production issues and implementing sustainable fixes.

Requirements

• Seniority & Ownership: 5+ years of software engineering experience with a proven track record of owning features from conception to production deployment.
• Product-First Mindset: You treat code as a tool to solve user problems. You are comfortable questioning requirements, identifying gaps in user stories, and advocating for the best technical solution.
• Backend Expertise: Deep proficiency in Ruby on Rails; you understand the framework’s nuances and know how to build, maintain, and scale robust backend systems.
• Technical Rigor: Deep understanding of relational database design, query optimization, and architectural trade-offs. You prioritize maintainability and security (e.g., HIPAA/SOC 2 compliance) in every decision.
• Communication: Excellent written and verbal communication skills. In a remote-first team, your ability to document decisions and communicate asynchronously is as critical as your coding skills.
• Adaptability: Experience working in fast-paced startup environments where requirements evolve and ambiguity is the norm.

Nice to Have

• Mission-Critical Systems: Prior experience building software where reliability is paramount (e.g., healthcare, fintech, or life-safety applications).
• Full-Stack Depth: Direct experience with our frontend stack (React, Flutter).
• Cloud Infrastructure: Hands-on experience with AWS (ECS, RDS, S3) and modern DevOps practices that allow small teams to move fast.
• Physical/Digital Intersection: Experience working with hardware-connected software (IoT) or building applications that handle intermittent/offline connectivity.
