Senior Full Stack Engineer

ABOUT THE ROLE: We’re not looking for “just another engineer.” We’re looking for someone who thrives in the gray zone between chaos and creation. At Talon.One, you’ll help us move at high speed through prototypes, experiments, and wild ideas—most of which won’t survive, but the few that do could shape the future of our product. This isn’t about polished, production-grade code. It’s about speed, creativity, and an appetite for risk. You’ll work directly with our CPO, CEO, and other product leaders to translate brainwaves into working demos, test them with customers, and uncover the gems worth scaling. If you love building things that might get thrown away tomorrow but could inspire the next big thing—this is your playground. ONCE YOU ARE HERE YOU WILL: Rapidly build prototypes and MVPs across the stack to test product ideas. Work closely with stakeholders to turn napkin sketches into demos that feel real. Iterate fast—scrap what fails, double down on what works. Use modern AI tools (Gemini, ChatGPT, Claude, etc.) to accelerate development and ideation. Collaborate with internal teams and customers to validate assumptions. Inject creativity, challenge conventions, and embrace “crazy ideas” as part of the process. WHAT WE NEED YOU TO BRING TO THE TABLE: Strong JavaScript / TypeScript skills. Experience with Node.js and modern frontend frameworks (React, Next.js, or similar). Ability to move across the stack with pragmatism and speed. Curiosity and openness to experimentation—even failure excites you. Strong communication skills, and the ability to switch contexts quickly. Collaborative mindset—comfortable working directly with executives and bouncing ideas around. Bonus points for: Experience with Go (many of our systems run on it). Background in startups, innovation labs, or fast-moving prototyping teams. Hands-on experience with AI-assisted development tools (Gemini, Claude, Copilot, ChatGPT).
