The Company
We are Alloy Therapeutics—a biotechnology ecosystem company empowering the global scientific community to make better medicines together. Through a community of partners, we democratize access to pre-competitive tools, technologies, services, and company creation capabilities that are foundational for discovering and developing therapeutic biologics. The company facilitates affordable, non-exclusive access to the entire drug discovery community from academic scientists, small and medium biotech, to the largest biopharma. At Alloy, we believe our industry should compete on getting the best drugs to patients as quickly as possible, not exclusive access to the best platforms. As a reflection of our relentless commitment to the scientific community, we reinvest 100% of its revenue in innovation and access to innovation. MAY THE BEST DRUG WIN.
Alloy is headquartered in Waltham, MA with additional labs in Basel, CH; Cambridge, UK; and Athens, GA. Successful members thrive in our shared culture of accountability, deliberate trust, and open communication. As a team we aspire to work together to exceed expectations and collectively contribute across the global organization to always maintain our nimble, startup culture. Come thrive at Alloy!
The Team
The Senior AI Software Engineer will join the Insights team. This team builds internal and external software products that power Alloy’s operations, partner portals, and data platforms. Team members collaborate closely with engineering, product, and scientific teams to deliver modern, scalable, and intuitive applications supporting Alloy’s mission of accelerating drug discovery through technology.
The Role
As a Senior AI Software Engineer, you will design, build, and maintain end-to-end web and AI-driven applications that leverage large language models (LLMs) and Alloy’s proprietary data to deliver intelligent, interactive tools for scientists and engineers. You will have ownership over key technical decisions across the AI stack, including architecture design, model selection, and tradeoffs between retrieval-based and model-adoption approaches.
Your primary focus will be on developing a conversational AI agent with a ChatGPT/Cursor-style interface that integrates securely with Alloy’s unique data ecosystem. This agent will act as an intelligent assistant helping users explore experimental data, automate workflows, and derive insights from complex scientific information.
You will operate across the stack, from LLM integration and vector database design to full-stack web interfaces and production deployment, collaborating with data scientists, bioinformaticians, and software engineers to deliver impactful, real-world tools.
This role requires a hands-on builder with strong engineering fundamentals, curiosity about AI systems, and comfort working in an environment that encourages innovation and experimentation.
You will report to the Head of the Insights division and have autonomy in owning multiple projects, collaborating with international teams, and delivering production-quality AI products. As the team grows, the role offers scope to expand technical leadership responsibilities and influence the long-term AI platform strategy.
