SandboxAQ is seeking a backend engineer generalist to contribute to our drug discovery and chemistry simulation platform. You’ll get exposure to a wide variety of areas, including:

• Core application development -  we’re building a platform that powers our R&D in life sciences and chemistry simulation. You will contribute to its core functionalities, APIs, and data and control planes.
• DevOps -  you will contribute to build, testing, and deployment pipelines for a complex set of build artifacts and IaC-managed infrastructure.
• User and product work - you will work closely with the researchers that are using the software you’re building and you’ll immediately get to see your impact. You’ll work with the product team to gather and prioritize the feedback.

You’ll bring experience writing high-quality, readable, well-tested code. You will have experience with API design, database fundamentals, and CI/CD pipelines. You’re entrepreneurial and customer-obsessed. Most importantly, you’ll bring a track record of working in a fast-moving software development team, exploring new technologies, and solving problems across an entire software stack.

• Contribute to the development of SandboxAQ’s chemistry and life sciences simulation platform.
• Work closely with users and members of the product team to measure the impact of the code you develop on users, gather feedback, and iterate on your software.
• Participate in planning, design, and sprint ceremony meetings.
• Embed closely with R&D teams to assist in delivering project goals and drive adoption of practices and tooling.
• Collaborate closely with the product team and internal stakeholders in all phases of software development to validate the solutions you propose and implement.

• Exposure to Terraform or another IaC system, along with DevOps and GitOps.
• Knowledge of CI/CD best practices and building CI/CD pipelines.

• Domain experience in advanced materials, drug discovery, cheminformatics, or other areas of chemistry or biology, especially experience with AI systems applied to these domains.
• Delivering scientific code for R&D projects, especially in the simulation and numerical optimization domains
• HCP systems, GPU programming and optimization
• AI applications in knowledge graphs, AI agents, and multi-agent systems.
