Software Engineer

Responsibilities

• Ship full-stack features end-to-end, owning the full lifecycle from conception to production with minimal oversight.
• Build and maintain the infrastructure powering Fastino's services, keeping systems reliable and performant as we scale.
• Work directly with AI researchers to bring new model capabilities into the product, moving fast without sacrificing quality.
• Translate user feedback into product improvements, closing the loop quickly between what customers experience and what gets shipped.
• Collaborate daily with the full team to review progress, surface blockers, and keep velocity high.

Requirements

• 3+ years of hands-on software engineering experience, with a track record of owning features from design to deployment.
• Strong Python skills; comfort in TypeScript is a plus but not required.
• You thrive in ambiguity and can balance speed and scalability without needing a playbook.
• Experience building or integrating with LLM-based systems or AI infrastructure (optional).
• Familiarity with high-concurrency backend systems or low-latency API design (optional).
