Founder @ Techmunity | 400+ software & AI startup teams built | 70+ recs from founders, CTOs, investors & engineers | CodeYourFuture partner

Are you a Full Stack Engineer who's interested in all things AI and startups?

Want to work 100% remotely on a game-changing product?

Techmunity is partnering with an AI-native startup backed by top-tier investors (seed-stage, $11M raised, $50M+ valuation) that’s transforming customer support.

Imagine Intercom or Zendesk, but reimagined with reasoning-capable AI agents that actually solve problems, not just escalate them.

You’ll join an async-first, 15+ engineering team who're shipping real features fast and independently, with minimal meetings and maximum ownership.

The product is live with paying enterprise clients, unlocking $100k+ ACVs and white-glove onboarding experiences - and now they’re scaling rapidly.

They’re looking for Senior and Staff Full Stack Engineers with proven experience building scalable, high-impact products at established companies or startups that have successfully scaled.

What You’ll Do

• Own and deliver full stack features across a modern AI-integrated stack: React, Next.js, TypeScript, Node.js, PostgreSQL
• Build highly available backend services and APIs powering multi-channel AI agent interactions
• Work with AWS infrastructure (Lambda, Fargate, EC2, SQS), Redis, Terraform/CDK, and GitHub Actions
• Collaborate closely with design- and product-focused founders—craftsmanship and UX polish are critical
• Help shape our engineering culture, raise standards, and champion async workflows

Who You Are

• 7+ years experience building and scaling real-world systems, ideally at Series B–D startups or reputable enterprises
• Proven ability to lead features from 0 to 1 independently and pragmatically
• Deep backend knowledge: Node.js, microservices, API design, cloud infrastructure
• Strong frontend skills: React, Next.js, TypeScript, with a focus on usability and clean design
• Exceptional async communication skills—clear, proactive written updates are essential in our remote-first team
• Bonus: Experience with LLMs, Retrieval-Augmented Generation (RAG), or other AI/ML systems—or a strong desire to dive in

Why Join

• Competitive salary: $100k–120k USD, offered as a contract role through Deel (a trusted global payroll platform) for EU-based hires
• Generous equity package at an early-stage company
• Remote-first with preference for CET timezone overlap
• Tools you’ll love: Linear, Notion, GitHub Actions, Slack, ChatGPT Pro, Perplexity
• Unlimited holiday, parental leave, and a dedicated learning budget
