Lilly will not provide support for or sponsor work authorization or visas for this role, including but not limited to F-1 CPT, F-1 OPT, F-1 STEM OPT, J-1, H-1B, TN, O-1, E-3, H-1B1, or L-1 Additional Skills/Preferences Technical depth + Strong full-stack fundamentals. You're comfortable owning a feature from database schema to UI and have an opinion about each layer. + Solid API design and integration experience. You know how to build systems that connect things cleanly. + Real frontend craft: you can design and ship interfaces that feel right, not just functional. You sweat the empty states and the error states. + Cloud experience and comfort with modern deployment practices. + Enough familiarity with AI/ML to make good integration decisions. You don't need to be a data scientist, but you need to understand what you're wrapping and why it matters. + Always learning. You want the why behind an ask, not just the what, and you don't let momentum decide a solution for you. + Hands-on experience building LLM-powered features. You understand the practical challenges: reliability, evals, context management, and when not to use AI. + Comfortable with AI-assisted development tools (Cursor, Claude Code, etc.). You know how to get the most out of them. Product instincts + You think about the user, not just the system. You've built software that external customers actually paid for and relied on. + You've simplified complex backend capabilities into clean, usable product experiences. + You ask "what problem are we solving?" before "how do we build it?" + You talk product with a PM, not just specs. You'll raise "wait, why are we building this?" when it matters. + Focused on delivering business value, not just shipping features. You'll work directly with internal stakeholders and customers when it helps the team. Startup mentality + You've worked in environments where the roadmap wasn't fully defined and the team was small, and you thrived. + You unblock yourself and figure things out. You don't wait for a spec or hand-holding. + You create structure and process when needed, but you know when to skip it. + You take ownership broadly. If something isn't working, you fix it rather than wait for someone else to. + Startup experience matters here more than big-tech tenure. How you work + You bring judgment to your work. You speak up early when something looks off and update fast when you're wrong. + Low ego, high standards. You'll learn from a more junior engineer who knows the area better, and you'll push back firmly when you don't agree. + You communicate clearly across technical and non-technical audiences. Additional Preferences + Experience in life sciences, pharma, or health tech. + Background building B2B SaaS products. + Prior experience at a startup, or as an early engineer in an internal startup within a larger company. ## Description TuneLab has powerful underlying AI models and point solutions. The job now is to turn them into something a biotech startup can actually use: a coherent workflow, a clean product experience, and a SaaS offering that scales. You won't start from zero. There are working point solutions, trained models, and internal infrastructure to build on. Federated learning is a meaningful part of the work - letting biotech customers use & train Lilly's models without their data leaving their environment. Plenty else is yours to create from scratch. We're looking for a Senior Software Engineer to be one of the early engineers on this team. You'll own meaningful product surfaces end-to-end, ship features that customers depend on, and raise the bar on what we build. You'll partner closely with a Staff Software Engineer and the Engineering Manager. You'll have real influence on architecture and the engineering bar. You'll work shoulder-to-shoulder with product, design, and data science, and report to the TuneLab Engineering Manager. Key Responsibilities Build the product + Own product surfaces end-to-end-frontend, backend, data, integrations-whatever the problem requires. You don't hand off; you ship. + Build the application layer that wraps Lilly's AI models into reliable, cohesive workflows for biotech customers. + Drive features end-to-end. Take a fuzzy requirement, weigh the tradeoffs, and ship something that works. + Stay deep in the code. This is a build role, not a review role. + Contribute to the engineering bar-code review, testing, release process, on-call. Hold the standards we set. Lift the team + Mentor the engineers around you. Make them better at the job, not just better at this codebase. + Partner with PM and design on features. Speak up early when something feels off in the spec or the scope. + Help interview engineers as the team grows. Hold the bar. + Spot the things nobody owns and either pick them up or flag them clearly. Operate effectively inside a large company + Navigate enterprise infrastructure, security, and compliance requirements without disrupting development progress. + Work with Lilly IT and internal platform teams to leverage existing capabilities rather than rebuild them. ## Related Videos - [API Design - Getting Started](https://www.wearedevelopers.com/videos/33-api-design-getting-started) - [Developing the Backend with Stefan Lingler, CTO at Shpock](https://www.wearedevelopers.com/videos/100360-developing-the-backend-with-stefan-lingler-cto-at-shpock) - [Are Code Reviews Worth It?
