About The Position

We're hiring a Senior Full Stack Engineer to join our Management Apps team. You'll report to the Software Engineering Manager and work across the entire stack, building APIs and services on the backend while shipping polished, user-facing features on the frontend. This isn't a backend role with occasional frontend work or vice-versa. You'll be expected to move fluidly between both.
This is a high-ownership role. You'll partner with Product Management, Architects, and engineers across teams to ship features that give biotech and pharmaceutical companies actionable clinical and business insights. Someone who doesn't just write code but shapes technical direction.

Requirements

• 5+ years of professional software engineering experience, building web based, multi-tenant, commercial applications
• Strong engineering skills across the full stack in TypeScript. You've built and operated production-grade services and shipped production-grade UIs that real users depend on.
• Experience with relational databases (PostgreSQL preferred), including schema design, query optimization, and migrations.
• Proven ability to build effective UI in a modern React/TypeScript codebase. You're comfortable with component architecture, state management, and working with design systems.
• AWS experience building and deploying cloud-native applications. Familiarity with our specific services (CDK, Cognito, Lambda, SQS, EventBridge, S3) is a plus.
• Ability to navigate and debug across multiple layers of the stack (UI, services, databases, ETL pipelines)
• You've worked in a monorepo or multi-service architecture and understand the tradeoffs.
• You've shipped SaaS products and understand what it means to operate software, not just deploy it.
• Strong written and verbal communication skills, with the ability to articulate technical decisions and collaborate effectively across teams.
• You're comfortable with ambiguity and can make progress without perfect requirements.

Nice To Haves

• Healthcare domain experience or familiarity with HIPAA/SOC/HITRUST compliance requirements.
• Experience with infrastructure-as-code (AWS CDK, Tofu, Terraform, etc.).
• Experience leveraging AI tools like Claude to accelerate development workflows, automate repetitive engineering tasks, or integrate LLM capabilities into product features.
• You've been through hypergrowth at a startup and know what that demands.

Responsibilities

• Design and build APIs and services in our NestJS/TypeScript backend, including domain modeling, schema design, and service architecture.
• Build and iterate on user-facing features in our React/TypeScript frontend, turning wireframes and product requirements into production UI.
• Own features end-to-end: from understanding the problem with Product, through implementation on both sides of the stack, to production observability.
• Ensure the delivery of high-quality, reliable, and maintainable software by implementing comprehensive automated testing across the full stack (frontend, backend, and integration layers)
• Work within our AWS infrastructure and make informed decisions about service boundaries and cloud-native patterns.
• Proactively identify and resolve production issues. You care about system health, not just shipping.
• Mentor other engineers through code review, pairing, and architectural guidance.
