Agentic Fullstack Engineer

Full Time

Vilnus/ San Francisco / Bangkok / Singapore / Remote APAC & US

About the Role

We are looking for an Agentic Fullstack Engineer to design, build, and deploy AI-powered agentic systems on a modern Next.js and Laravel stack. You will bridge the gap between intelligent automation and reliable product engineering crafting the APIs, interfaces, and agent pipelines that power our core platform. This role is ideal for a developer who is deeply curious about AI agents and wants to build real, production-grade agentic workflows.

Key Responsibilities

  • Design and build agentic workflows using LLM APIs (OpenAI, Anthropic, etc.) integrated into Laravel backend services

  • Develop full-stack features across Next.js (frontend) and Laravel PHP (backend)

  • Architect agent orchestration logic: task routing, tool-calling, memory management, and multi-step reasoning

  • Build and maintain RESTful APIs and webhooks consumed by agent pipelines and frontend clients

  • Implement SSR, SSG, and App Router patterns in Next.js for optimal UX and performance

  • Create intuitive operator-facing dashboards to monitor, manage, and configure agents

  • Integrate third-party tools and APIs into agentic workflows (CRMs, communication platforms, data sources)

  • Write clean, well-tested code and participate in code reviews

  • Collaborate closely with operations and product teams to translate agent use cases into working systems


Required Qualifications

Frontend (Next.js & React)
  • 3+ years of professional full-stack development experience

  • Proficiency in React and Next.js including App Router, server components, and TypeScript

  • Comfortable with Tailwind CSS and building clean, functional UIs

  • Experience consuming REST APIs and streaming responses in the frontend

Backend (Laravel & PHP)
  • Strong experience with Laravel including Eloquent ORM, queues, jobs, and service containers
  • Comfortable with PHP 8.x features and writing clean, maintainable backend code

  • Experience building RESTful APIs consumed by JavaScript frontends and external services

  • Familiarity with MySQL or PostgreSQL, including schema design and query optimisation

  • Experience with Redis for caching and queuing

Agentic & AI
  • Hands-on experience building with LLM APIs (OpenAI, Anthropic, or similar)

  • Familiarity with agent patterns: tool-calling, function calling, multi-step reasoning, memory

  • Experience with prompt engineering and building reliable, structured AI outputs

  • Understanding of agentic frameworks (LangChain, LlamaIndex, CrewAI, or equivalent) is a plus

Tooling & Practices
  • Solid Git workflow and experience with CI/CD pipelines

  • Comfortable with Docker for local development

  • Familiarity with cloud platforms: AWS, GCP, or DigitalOcean

Nice to Have

  • Experience with Inertia.js for Laravel + React integration

  • Prior work on multi-agent systems or autonomous pipelines

  • Exposure to vector databases (Pinecone, Weaviate, pgvector)

  • Experience with streaming UIs and real-time agent output rendering

What We Offer

  • Competitive salary based on experience and location

  • Performance-based bonus

  • This is a full-time position. We begin with a 2-month paid trial to ensure mutual alignment candidates who demonstrate the right skills and mindset will transition seamlessly into the permanent role.

  • Annual learning & development budget (courses, conferences, books)

  • Modern tooling and a team that values excellence and ownership

  • Flat hierarchy, collaborative culture, and real impact on the product

  • Growth path into senior and leadership roles

Education

  • Bachelor's degree in a relevant field or equivalent practical experience

  • A strong portfolio of shipped work or demonstrated results will be equally considered
