  • Collaborate closely with product and design to prototype and ship impactful solutions quickly

What You'll Bring

  • 5+ years of software development experience, with deep knowledge of JavaScript/TypeScript
  • Experience with AWS Serverless development (e.g., Lambda, DynamoDB, SQS)
  • Experience integrating LLM/AI APIs (e.g., OpenAI, Anthropic, etc.)
  • Experience with Next.js
  • Understanding of key AI concepts, including:
    • Temperature tuning
    • Embeddings and vector search
    • Retrieval-Augmented Generation (RAG)
    • Conversation memory management
    • Function calling and chaining
    • Prompt engineering techniques
  • Experience building and deploying full-stack applications
  • Nice to have:
    • Prior experience working on AI/LLM-integrated products
    • Familiarity with tools like Pinecone, Weaviate, or LangChain
    • Knowledge of CI/CD pipelines and infrastructure-as-code

What You'll Get

  • Competitive salary, bonus opportunity, and equity package
  • Comprehensive Medical, Dental, and Vision benefits
  • A 401k retirement plan
  • Paid vacation and company holidays
  • Opportunity to make an impact at a rapidly growing mission-driven company transforming healthcare in the U.S.

Safe Remote Job Search Tips

Verify Employer Thoroughly

Research the company's identity thoroughly before applying. Check for a professional website with contacts, active social media, and LinkedIn profiles. Verify details across platforms and look for reviews on Glassdoor or Trustpilot to confirm legitimacy.

Never Pay to Get a Job

Legitimate employers never require payment for applications, training, background checks, or equipment. Always reject upfront payment requests or demands for bank details, even if they claim it's for purchasing necessary work gear on your behalf.

Safeguard Your Personal Information

Protect sensitive data like SSN, bank details, or ID copies. Share this only after accepting a formal, written job offer. Ensure it's submitted via a secure company system or portal, never through insecure channels like standard email attachments.

Scrutinize Communication & Interviews

Watch for communication red flags: poor grammar, generic emails (@gmail), vague details, or undue pressure. Be highly suspicious of interviews held only via text or chat apps; legitimate companies typically use video or phone calls.

Beware of Unrealistic Offers

If an offer's salary or benefits seem unrealistically high for the work involved, be cautious. Research standard pay for similar roles. Offers that appear 'too good to be true' are often scams designed to lure you into providing information or payment.

Insist on a Formal Contract

Always secure and review a formal, written job offer or employment contract before starting work or sharing final personal details. Ensure it clearly defines your role, compensation, key terms, and conditions to avoid misunderstandings or scams.
