Soulside AI - Full Stack Developer

Remote - USA+ Equity2d ago

Requirements

• End-to-End Owner: You're comfortable moving between pixel-level UI polish and backend architecture, and you own features from design through production. • End-to-End Owner: • Detail-Obsessed: You have an eagle eye for precision—you notice the small inconsistencies others miss, whether in UI alignment or data structures. • Detail-Obsessed: • Systems Thinker: You reason naturally about distributed systems, failure modes, and data consistency. You design for what goes wrong, not just what goes right. • Systems Thinker: • Problem Solver: You're resourceful and can find smart technical solutions when faced with complex, non-standard requirements or scaling challenges. • Problem Solver: • Ownership Mindset: You're happy to roll up your sleeves for both high-level feature work and the critical "last-mile" details that make a production system successful. • Ownership Mindset: • 2+ years of software engineering experience building production applications. • Strong proficiency in TypeScript and JavaScript, with hands-on experience building interfaces in React. • TypeScript and JavaScript • React • Experience managing complex application state and data flows on the frontend. • Familiarity with modern CSS frameworks (Tailwind, etc.) and responsive design. • Solid backend experience with Java and the Spring Boot framework for building production-grade services. • Java and the Spring Boot framework • Experience designing and consuming REST APIs and integrating frontend and backend systems. • Familiarity with distributed systems and message queues / streaming platforms (SQS, Kafka, or Kinesis). • Working knowledge of cloud infrastructure (AWS preferred—EC2, ECS/EKS, auto-scaling). • Ability to thrive in a fast-paced, remote startup environment. • Excellent communication skills to collaborate with both technical and non-technical team members. • Must be authorized to work in the United States. • LLM Proficiency: Hands-on experience with prompt engineering to refine and validate structured AI outputs, plus usage monitoring and quality metrics. • LLM Proficiency: • Observability: Experience with monitoring and alerting tools such as Prometheus and Grafana. • Observability: • Security & Compliance: Experience with Spring Security, RBAC, and healthcare compliance standards (HIPAA). • Security & Compliance: • Reliability Patterns: Experience with redundancy, circuit breakers, retries, and graceful failure handling. • Reliability Patterns: • Architecture: Event-driven architectures, microservices patterns, or Domain-Driven Design (DDD). • Architecture: • Infrastructure as Code: Terraform, or experience with additional cloud platforms (GCP, Azure). • Infrastructure as Code: • Performance Optimization: Proven ability to improve speed and efficiency in data-intensive applications. • Performance Optimization: • Internal Tooling: A track record of building admin dashboards or automation scripts to simplify manual engineering tasks. • Internal Tooling: • Healthcare technology background, audio/signal processing, real-time systems, or open source contributions.

Responsibilities

• Full-Stack Feature Development: Build and maintain responsive, high-fidelity web applications using React and TypeScript, backed by core services written in Spring Boot. • Full-Stack Feature Development: • Backend & Distributed Systems: Architect and develop backend services that process sensitive healthcare data, leveraging message queues and streaming platforms (SQS, Kafka, Kinesis) for high-volume asynchronous workloads. • Backend & Distributed Systems: • Complex Data Implementation: Design and implement the technical logic and schemas that power the platform, translating multifaceted domain requirements into structured, scalable configurations across the frontend and backend. • Complex Data Implementation: • LLM Integration: Design and optimize LLM pipelines, including prompt engineering, usage monitoring, and quality assurance to validate structured AI outputs. • LLM Integration: • Reliability & Observability: Implement monitoring, alerting, and observability (e.g., Prometheus, Grafana), along with data reliability patterns such as redundancy, retries, and graceful failure handling. • Reliability & Observability: • Security & Compliance: Apply security best practices using Spring Security, implement RBAC, and help ensure HIPAA compliance for clinical data. • Security & Compliance: • Platform Reliability: Proactively identify, troubleshoot, and resolve bugs and support issues across the stack to ensure a seamless experience for clinicians. • Platform Reliability: • Foundational Decisions: Make technical decisions—and build the internal tooling and workflows—that will scale as we grow from ten clinics to ten thousand. • Foundational Decisions: • Collaboration: Work directly with founders and clinical teams to translate healthcare needs into scalable technical solutions. • Collaboration:

Benefits

• Own features end-to-end—from the React interfaces clinicians touch every day to the distributed backend services that process sensitive healthcare data. • Work directly with founders on architecture decisions that will scale with our growth. • Build across the full stack: high-fidelity UIs with React & TypeScript, and distributed systems using Spring Boot & Kafka. • Ship technology that directly reduces clinician burnout and expands access to quality mental health care. • Our momentum speaks for itself: • ✅ Backed by Counterpart Ventures, GreyMatter Capital, Sarah Smith Fund & Kaya Ventures ✅ UCSF Rosenman Healthtech Innovator 2024 ✅ OneMind Accelerator 2024 & PeakXV Spark Program ✅ Global Top 10 - Confluent Data Streaming Challenge • Competitive salary commensurate with the role. • Meaningful equity package with high upside potential as an early team member. • Comprehensive health, dental, and vision insurance. • Flexible work arrangements with a remote-first culture (USA-based). • Direct access to founders and influence on company direction. • Professional development budget and conference attendance. • Modern tech stack and autonomy over technical decisions. • Opportunity to help build something meaningful that impacts mental health at scale. • Send us your resume along with a brief note about what excites you about this role and any relevant projects you've worked on. We'd particularly love to hear about full-stack features you've owned end-to-end, and any work you've done with distributed systems, React applications, or LLMs and AI systems in production.
