Full Stack Software Engineer

Compensation: $120,000 – $130,000 Base Salary + Benefits

Location: Fully Remote (Option to work hybrid out of our Venice, CA office)

About SonoSim & The Role

At SonoSim, we create user-friendly digital experiences that transform medical education and improve healthcare outcomes. Our engineering team is a bright, motivated, and highly collaborative group. We partner closely across product and design stakeholders to deliver high-quality software that solves real-world needs for medical professionals and institutions.

We are seeking a mid-level Full Stack Software Engineer (4+ years experience) to build, ship, and scale core features across the SonoSim LMS platform. Working alongside Lead, Senior, and Junior Engineers, you will navigate between projects and repositories with minimal oversight. You thrive in modern, AI-assisted development workflows and enjoy driving features from database schema design to polished user interfaces.

Core Responsibilities

• End-to-End Feature Delivery: Own features across our primary stack—from database schema design and migrations in Prisma to backend logic (Express, tRPC) and modern UI delivery (Angular with Signals).
• Cross-Service Integration: Maintain cross-service awareness and navigate legacy services (Python, Django, GraphQL, REST APIs) as needed.
• AI-Assisted Engineering Velocity: Leverage AI tools (Kiro, Claude, Codex) for rapid prototyping and boilerplate generation, applying human oversight for code quality and architectural standards.
• Testing & Quality Assurance: Ensure end-to-end feature integrity by validating API-to-UI handshakes, covering edge cases, and delivering maintainable code adhering to DRY/SOLID principles.
• Agile Teamwork & Practices: Maintain shared documentation and actively participate in team ceremonies (stand-ups, sprint planning, retrospectives, code reviews) to foster continuous improvement.

Qualifications & Requirements

• 4+ years of professional full-stack web development experience with demonstrated autonomy across multiple repositories.
• Frontend & Backend Expertise: Hands-on experience with Angular and Node.js backends (Express).
• APIs & ORMs: Proficiency with type-safe APIs (tRPC), ORMs (Prisma), and relational database management/migrations.
• Legacy Support: Familiarity with REST, Python, Django, and/or GraphQL for service maintenance.
• AI Tooling & Review: Comfort using AI-assisted coding tools paired with critical code review skills.
• Collaboration & Communication: Strong communication skills with a team-first, pragmatic mindset for collaborative development.
