Senior Software Engineer

Purple Squirrel Enterprises provides HR and recruiting solutions and is exclusively supporting a mission-driven health technology company building an integrated platform for care teams serving individuals with complex needs. The Senior Software Engineer will own full-stack features and platform components from architectural design through production deployment, while shaping product decisions, improving system reliability, mentoring teammates, and addressing technical debt.

Responsibilities:

• Build and maintain features across the full stack (Ruby on Rails, React, Flutter), taking end-to-end ownership from initial design through production deployment
• Act as a product-minded partner, translating complex user needs — often in early or ambiguous stages — into intuitive, technically sound solutions
• Operate with high autonomy, driving architectural decisions and navigating ambiguity to solve impactful engineering challenges
• Elevate the engineering culture by setting high standards, mentoring teammates, and simplifying processes to help the team move faster as they scale
• Proactively balance feature velocity with long-term system health by identifying and addressing technical debt before it becomes a bottleneck
• Prioritize pragmatic simplicity, ensuring the team builds only what is necessary to validate assumptions and deliver value, while resisting complexity that hinders agility
• Ensure the reliability and performance of critical systems by taking ownership of production issues and implementing sustainable fixes

Requirements:

• 5+ years of software engineering experience with a proven track record of owning features from conception to production deployment
• Deep proficiency in Ruby on Rails — you understand the framework's nuances and know how to build, maintain, and scale robust backend systems
• 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
• 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
• Strong communication skills — in a remote-first environment, 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
• U.S. work authorization — our client is not able to provide visa sponsorship at this time
• Experience building software where reliability is paramount (e.g., healthcare, fintech, or life-safety applications)
• Direct experience with the frontend stack (React, Flutter)
• Hands-on experience with AWS and modern DevOps practices. Certifications will bolster your application
• Experience with systems that interact with physical devices or operate in low-connectivity environments
