Flatiron School is transitioning its engineering team into a modern product engineering organization focused on building the next generation of AI‑driven adaptive learning tools. As part of this shift, we’re creating a hybrid role for a senior engineer who can both contribute deeply to product development and lead the technical growth of our expanding apprenticeship program.

This position blends hands‑on engineering with leadership and mentorship. You will spend roughly half of your time designing, prototyping, and shipping product features and infrastructure. The other half of your time, you’ll guide apprentices as they develop real products and complete their part‑time Data Science bootcamp.

You’ll work directly with the VP of Product, help establish our product engineering culture, and shape how both senior developers and apprentices work together in a studio‑style environment.

• Full‑stack development of adaptive learning tools using React, Type Script, Python, and Postgres.
• Build maintainable infrastructure on modern stacks (Supabase, Vercel, AWS) to support product development.
• Rapidly turn product ideas into functional prototypes and iterate based on user insights.
• Integrate AI/ML frameworks (e.g., OpenAI, Hugging Face) into learner‑facing experiences.
• Define and enforce engineering best practices, including clean code, testing habits, and architecture patterns.
• Collaborate directly with product leadership on scope, priorities, and technical direction.

• Guide a cohort of part‑time apprentice engineers as they split time between development and the Data Science bootcamp.
• Design and maintain apprentices’ weekly development workflows, expectations, and milestones.
• Conduct code reviews, pair programming sessions, and small‑group technical coaching.
• Help apprentices understand how product thinking, engineering, and data science intersect.
• Create and refine templates, starter repos, and repeatable patterns that help new apprentices ship high‑quality work faster.
• Partner with the VP of Product to ensure apprentice work integrates smoothly with senior engineering output.
• Model professional engineering behavior, including clear communication, accountability, and problem‑solving.

• Ability to work in person in Columbia, SC, at least one day per week.
• 6+ years of experience in full‑stack development (e.g., Next.js, JavaScript, Type Script, Python, SQL).
• Experience with rapid development environments (e.g., Supabase, Vercel, AWS).
• Familiarity with AI/ML tool chains and APIs.
• Strong experience breaking down work for junior developers or mentoring engineers.
• Ability to balance hands‑on coding with supervision and process‑building.
• Comfortable working in a fast‑moving, early‑stage product environment.
• Can work in the US without visa…
