AI Technical Lead

About us

At Vazco, we don’t just follow technology trends – we redefine what’s possible with AI. Every project we take on is a chance to build meaningful digital experiences powered by smart, scalable AI solutions. Whether we’re automating complex processes, enhancing user journeys, or enabling data-driven decisions — we’re here to make innovation real.

Excited about solving tough challenges for startups, scale-ups, and enterprises around the world? Curious about how AI can drive real business value, not just hype? That’s the space we operate in. You won’t have to choose between commercial impact and meaningful tech — our portfolio includes Open Source projects, nonprofit work, and deep partnerships with forward-thinking companies.

Apart from that, you will find yourself in an authentic and open company culture. Our non-hierarchical structure means minimal management and transparent communication with everyone (including the CEO).

Now, let’s see what else makes joining our Crew so exciting! ⛵

• Strong background in TypeScript, Node.js, React, and Next.js.

• Proven experience leading AI projects end to end, from scoping and estimation to production rollout.

• Solid understanding of RAG architecture, vector databases, and LLM integrations.

• Experience with multi-agent frameworks, workflow orchestration, validation, and observability.

• Familiarity with textbots, voicebots, image/video generation, avatars, and automation systems.

• Ensuring technical excellence, code quality, and mentoring team members.

• Supporting the adoption of AI-UX and agentic design principles across products.

• Monitoring the performance and resilience of deployed systems to maintain quality over time.

What success looks like after 6 months

• Led 1-2 agentic projects end to end, from discovery through production launch.

• Established strong architecture standards for RAG and agentic systems.

• Mentored 3-5 engineers and helped raise the team’s technical bar.

• Improved production systems by reducing hallucinations, latency, and infrastructure costs.

Perks & Benefits

• Team-building & Company Events - After a day of focused work, there's nothing better than having a much-deserved mental break from responsibilities. Even better when it involves your pals! Be it a go-kart race with your team, a chill session of board games, or a couple of days in Prague - we do whatever fits our fancy. 🕺 

• Flexible working hours - Flexible working hours are not about being able to start your work within a specific timeframe. It's about maintaining the work-life balance you deserve. We have no strict "office hours" and embrace your early bird or night owl lifestyle. When you need to take a pause or manage your affairs, it's fine by us. However, we expect you to deliver the work on time and stay responsive on Slack if your colleagues need you (11-15 p.m.). 📲

• Training budget - Whether it comes to AWS, Domain-Driven Development, Public Speaking training, and many more, we can match you with the best tutors 🧑‍🎓. Show us the direction you'd like to grow in, and we'll go above and beyond to meet your expectations. 

• Personal branding - Build your true Pro status through blogging & social media activity as a company ambassador, your speeches at various conferences and meetups, hosting workshops, and participating in other exciting initiatives. Do it all with our backup. 🤝
