Senior Software Engineer

🚀 Senior AI Software Engineer

📍 Remote (UK Business Hours)

🏢 G LNK

💰 Up to $3,000/month

🕒 Full-time

G LNK is building the world’s largest searchable clinician database and the AI-native commercial intelligence platform on top of it.

We unify:

• 9.2M+ HCP profiles

• 68K+ hospitals & health systems

• $11B+ tracked payments

• 3B+ prescription claims

• 5B+ procedure claims

— into a single platform used by pharma, biotech, and medtech teams to search, analyze, segment, and act on healthcare data.

This is not “AI as a feature.”

AI is the product layer itself.

We are a small, highly technical, fast-moving team building infrastructure and intelligence systems around some of the most valuable healthcare datasets in the world.

We’re hiring a Senior AI Software Engineer to help architect and build the core systems behind the platform.

What You’ll Work On

• AI-powered search and semantic retrieval

• Agentic workflows and intelligent tooling

• Natural-language interfaces over massive healthcare datasets

• LLM systems, evaluation pipelines, and ranking infrastructure

• MongoDB architectures across billions of records

• Streaming AI experiences in React

• Embeddings, vector search, and analytics systems

You’ll work directly with the founder on architecture, product direction, and core technical decisions.

This is a high-ownership role for someone who likes solving hard engineering problems and building real production AI systems — not just stitching APIs together.

What We’re Looking For

• 6+ years of software engineering experience

• Strong experience building production AI / LLM systems

• JavaScript / TypeScript expertise

• Comfortable across React, Node.js, and MongoDB

• Strong understanding of:

• Retrieval systems
• Prompt engineering
• Agent architecture
• Evaluation frameworks
• AI system design

• Ability to move quickly, think independently, and build scalable systems from ambiguous problems

• Experience working with large, messy datasets and turning them into reliable product experiences

• Strong written and spoken English communication skills are essential — this role involves frequent live collaboration with the team and clear communication is extremely important

Nice to Have

• Healthcare data experience (claims, HCP, NPI, EHR, Open Payments, etc.)

• Experience with RAG systems and vector databases at scale

• Background building agentic systems or tool-using AI workflows

• Familiarity with HIPAA, SOC 2, or enterprise security standards

• Startup or founding engineer experience

Important

This is a remote role, but candidates must work UK business hours and be comfortable collaborating closely with the team on Zoom throughout the week.

We care deeply about:

• Speed

• Product quality

• Ownership

• Engineering standards

• Shipping real systems that customers use every day

If that sounds like your environment, we’d like to speak with you.
