[Remote] Senior Software Engineer, TuneLab

Note: The job is a remote job and is open to candidates in USA. Eli Lilly and Company is a global healthcare leader headquartered in Indianapolis, Indiana, dedicated to improving health through innovation. They are seeking a Senior Software Engineer to enhance their TuneLab AI/ML platform, focusing on creating user-friendly workflows and product experiences for biotech startups.

Responsibilities

• 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
• 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
• 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
• Join customer conversations when it helps. You can hold your own technically with a counterpart on the other side

Skills

• Bachelor's degree in Computer Science, Engineering, or a related field
• 5+ years of software engineering experience, with a track record of shipping software that real customers used and relied on
• Experience as a senior engineer on a product team–ideally a small one
• Qualified applicants must be authorized to work in the United States on a full-time basis. 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
• 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
• 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
• 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
• 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
• 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

Benefits

• Full-time equivalent employees also will be eligible for a company bonus (depending, in part, on company and individual performance).
• Lilly offers a comprehensive benefit program to eligible employees, including eligibility to participate in a company-sponsored 401(k); pension; vacation benefits; eligibility for medical, dental, vision and prescription drug benefits; flexible benefits (e.g., healthcare and/or dependent day care flexible spending accounts); life insurance and death benefits; certain time off and leave of absence benefits; and well-being benefits (e.g., employee assistance program, fitness benefits, and employee clubs and activities).
