Who We’re Looking For

We’re looking for a hands-on Tech Lead to design and build the technical foundation of a biotech startup operating in the cloud (AWS). This role combines architectural thinking with hands-on coding — you’ll lead technical discussions, shape the stack, and still contribute directly to the codebase.

The ideal candidate has a strong full-stack background with TypeScript, React, and databases, plus deep AWS expertise. Experience with AWS Amplify Gen 2, DynamoDB, Bedrock, and OpenSearch is a big plus. You should be comfortable collaborating with stakeholders and guiding a small team in a fast-moving startup environment.

What You’ll Be Doing

  • Design scalable and secure architecture for a cloud-based platform
  • Contribute directly to the codebase (hands-on coding in TypeScript, React, and backend)
  • Collaborate with product, engineering, and business stakeholders to align technical direction
  • Lead technical discussions and set engineering best practices
  • Define the stack, system components, and technical roadmap
  • Review code, mentor engineers, and ensure high-quality delivery
  • Work closely with data teams to design data flows and scalable storage
  • Oversee deployment and infrastructure management in AWS

What We Expect

  • 5+ years of hands-on full-stack development with AWS
  • Proven experience as a Tech Lead, Principal Engineer, or similar
  • Strong background in TypeScript, React, and modern full-stack development
  • Solid knowledge of AWS infrastructure (deployment, monitoring, scaling)
  • Understanding of software architecture patterns (microservices, event-driven, serverless)
  • Database design and optimization experience
  • Excellent communication skills, able to engage with both technical and non-technical stakeholders
  • Fluent English (Upper-Intermediate or higher)

Nice to Have

  • Data engineering or building analytical systems
  • Experience in healthtech or biotech
  • Launching greenfield projects or scaling startup architectures
