Overview

Kaiden AI is seeking a Senior Full-Stack Engineer to help build the future of public safety training.

Description

Kaiden AI is hiring a Senior Full-Stack Engineer to build critical systems that power our voice-driven simulation platform. You'll work across frontend, backend, and cloud infrastructure to deliver products that improve real-world law enforcement training.

This role is ideal for engineers who want true ownership, thrive under pressure, and move fast without waiting for permission.

About Kaiden AI

Kaiden AI is a venture-backed public safety tech company delivering voice-driven training simulations for law enforcement. Our platform helps officers practice high-stakes scenarios—crisis calls, jail operations, investigations—through realistic AI-powered interactions. Used by police departments and academies nationwide, Kaiden improves de-escalation, decision-making, and mental health response.

What You’ll Do

• Build & Ship: Architect and develop full-stack features using Next.js, TypeScript, Python, and SQL/NoSQL.
• Own Infrastructure: Optimize and manage cloud-native systems on AWS, GCP, or Azure.
• Set the Bar: Lead code reviews, mentor teammates, and define technical standards.
• Work with Users: Translate real-world needs from officers, trainers, and academy directors into smart product decisions.
• Ensure Quality: Drive testing, performance, and security practices across the stack.
  
  

What We’re Looking For

• Strong builder with 4+ years of full-stack development experience.
• Proficiency in Next.js, Python, TypeScript, and modern cloud platforms.
• Experience designing and managing both SQL and NoSQL databases.
• Ability to thrive in fast-paced, high-ownership environments—especially early-stage startups.
• Strong communicator and collaborator across technical and non-technical teams.
  
  

Bonus Points For

• Experience with voice AI, speech-to-text, or real-time systems.
• Background working in mission-critical sectors (e.g. law enforcement, defense, healthcare).
• Familiarity with security, compliance, or high-scale infrastructure.
  
  

This Role is Not for Everyone

• If you need a full spec before you start building—this may not be the right fit.
• If you want a job where you’re simply told what to do—this won’t work.
• If you shy away from pressure—you’ll likely hate it here.
• We’re looking for someone who leads without being asked, thrives on challenge, and moves with urgency.
  
  

Why Join Us

• Impact that matters: Your work shapes how officers train for real-world, high-stakes decisions.
• Real ownership: You’ll have autonomy to lead and influence product, tech, and process.
• Mission-driven team: We’re small, fast, and serious about doing meaningful work.
• Remote-first culture: Work where you do your best work.
• Competitive salary + meaningful equity
• Backed by respected investors: Focal Ventures, Hustle Fund, 43.vc, and top angels in tech and government.
  
  

If you're ready to build with urgency, lead with confidence, and code for real impact—we want to hear from you.
