About The Position

Purple Squirrel Enterprises is partnering with a high-growth health technology company to find an exceptional Senior Software Engineer. This role involves end-to-end responsibility for key features and platform components within a full-stack ecosystem including Ruby on Rails (backend), React (web), and Flutter (mobile). The ideal candidate is a pragmatic, product-minded engineer who understands user needs and engineering tradeoffs, and can own work from architectural design through production deployment. This is a remote-first, early-stage company with a lean, high-performing engineering team focused on building an integrated platform to help care teams deliver safer, more consistent support to individuals with complex needs.

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

Nice To Haves

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.

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
