Senior Software Engineer

Impruvon is a mission-driven startup focused on transforming medication management for vulnerable populations through innovative software and connected hardware. The Senior Software Engineer will take end-to-end responsibility for key features and platform components, ensuring system reliability and performance while actively shaping the product experience.

Responsibilities:

• Build and maintain features across our full stack (Ruby on Rails, React, Flutter), taking end-to-end ownership from initial design through production
• 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 our engineering culture by setting high standards, mentoring teammates, and simplifying processes to help the team move faster as we 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 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:

• 5+ years of software engineering experience with a proven track record of owning features from conception to production deployment
• 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
• Deep proficiency in Ruby on Rails; you understand the framework's nuances and know how to build, maintain, and scale robust backend systems
• 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
• 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
• Experience working in fast-paced startup environments where requirements evolve and ambiguity is the norm
• Prior experience building software where reliability is paramount (e.g., healthcare, fintech, or life-safety applications)
• Direct experience with our frontend stack (React, Flutter)
• Hands-on experience with AWS (ECS, RDS, S3) and modern DevOps practices that allow small teams to move fast
• Experience working with hardware-connected software (IoT) or building applications that handle intermittent/offline connectivity
