Fullstack Engineer

Job description

ABOUT BABA Baba is an applied AI lab modernizing risk and care delivery for people with Medicare. We've become the fastest growing digital health system matching people with Medicare and their family caregivers with expert advocates, physicians, medications, lab testing, and AI agents to deliver insurance-covered care across all 50 states. In the last 8 months, we've completed tens of thousands of appointments and partnered with health plans covering more than 4 million Medicare beneficiaries. On any given day, our team's work spans population health research, applied AI research, clinical care delivery, and fintech infrastructure. We're a Series A company with $40M+ in funding. Our team is half engineers, a third former founders, and comes from places like Ramp, Stripe, Liquid AI, Palantir, MIT, and CMU. Our clinical operations are led by the former Executive Director of Care Transitions from the Mount Sinai Health System. We believe that talent density is our greatest competitive advantage. ABOUT THE ROLE Baba is seeking a Fullstack Engineer to own the end-to-end development lifecycle for new platform capabilities and integrations with other systems. You'll own core systems end-to-end — from voice AI infrastructure to the internal tools our clinicians use daily. As we scale from thousands to millions of patients, you'll design the APIs, data pipelines, and product surfaces that make that possible without sacrificing quality of care. Interested candidates should email connor@callbaba.com with a short summary of the most challenging problem they've worked on and a link to their LinkedIn. WHAT YOU’LL DO - Build and maintain the web applications, APIs, and backend services that power Baba's patient advocacy platform. - Design and implement automated QA and monitoring systems to audit patient outcomes and advocate performance at scale. - Develop internal tools and dashboards that streamline clinical workflows, replacing manual processes with reliable, scalable software. - Architect data models and pipelines to support a growing marketplace of advocates, providers, and patients. - Collaborate directly with the founder and clinical team to translate operational bottlenecks into shipped product. WHO YOU ARE - Strong builder: You have 2+ years of professional experience building and shipping web applications. You're comfortable owning features end-to-end, from database schema to UI. - Systems thinker: You can map complex, multi-user workflows into clean data models and logical service boundaries. - Pragmatic and fast: You prioritize shipping over perfection, but you don't cut corners on correctness. You thrive in early-stage ambiguity. - High-agency: You take ownership of problems, not just tickets. When something breaks at midnight, you fix it. - Willing to sweep the corners: You're equally comfortable debugging a production issue, answering a patient support ticket, or whiteboarding system architecture. No task is below you. WHAT YOU NEED - 2+ years of professional engineering experience (excluding internships) in relevant roles at tech and product-driven companies - Are proficient in one or more backend languages (e.g., Python, Go, Rust, Typescript or similar) and distributed systems concepts. - Care deeply about reliability, safety, and performance in production environments. - Interest in AI/ML (direct experience not required) - Proven ability to thrive in fast-growing, product-driven companies by effectively navigating loosely defined tasks and managing competing priorities or deadlines. - Bonus: Former founder, or early engineer at a startup who has built a product from scratch BENEFITS - Medical, dental & vision insurance coverage - 401k - Flexible PTO - Free lunch & dinner in office - Relocation support to NYC (as needed)
