Position overview

We are seeking a Full Stack Engineer who builds with AI in the loop — both as a daily development practice and as a product capability. You are fluent with coding agents (Claude Code, Cursor, Copilot) and ship faster because of them, not despite them. You understand how to design, prompt, evaluate, and operate LLM-backed features in production — including model selection, context engineering, evals, guardrails, and cost and latency tradeoffs.

Beyond AI, you have deep Golang and React/TypeScript expertise and own features end-to-end: from understanding business requirements, through writing and testing code, to deployment and production monitoring. This role requires strong autonomy, proactive communication, and the ability to deliver reliable, scalable solutions in a modern cloud environment.

This position operates according to the CET time zone.

Responsibilities

• Design and ship LLM-powered product features: prompt design, retrieval, tool and function calling, structured outputs, streaming, evaluation harnesses, and guardrails.
• Operate AI features in production: monitor quality, latency, cost, and failure modes; iterate on prompts, models, and architectures based on real usage.
• Use AI coding tools (Claude Code, Cursor, Copilot) as a core part of your workflow to accelerate delivery without compromising code quality.
• Design, develop, and maintain backend services using Golang and frontend applications using React/TypeScript.
• Collaborate with product managers, designers, and other engineers to translate business requirements into technical solutions.
• Implement event-driven architectures leveraging Kafka for real-time data processing.
• Manage and optimize AWS environments, ensuring scalability and reliability.
• Define and maintain infrastructure using Terraform and deploy services in Kubernetes clusters.
• Build and maintain CI/CD pipelines in Jenkins for automated deployments.
• Ensure high-quality code through comprehensive testing and code reviews.
• Monitor application performance and troubleshoot issues in production environments.
• Contribute to UI/UX improvements and ensure seamless integration between frontend and backend.

Requirements

• Demonstrable production experience shipping LLM-powered features. Be ready to walk through a feature you built: prompts, evaluation approach, failure modes you fixed, and how you measured success.
• Hands-on with at least one major LLM provider's API (Anthropic, OpenAI, AWS Bedrock, or equivalent), including streaming, tool use, and structured outputs.
• Daily use of AI coding assistants in your workflow; able to articulate where they help, where they hurt, and how you maintain code quality.
• Strong, in-depth knowledge of Golang.
• Experience delivering complex backend systems from design to production.
• Solid background with Kafka and event-driven architectures.
• Hands-on experience managing AWS environments.
• Proficiency with Terraform for infrastructure-as-code.
• Experience deploying and operating services in Kubernetes.
• Building CI/CD pipelines in Jenkins.
• Proven ability to ensure quality through comprehensive testing.
• Strong proficiency in React and TypeScript.
• Experience contributing to front-end features, UI components, and client-side logic.
• Ability to seamlessly integrate frontend with backend services.
• Excellent English communication skills, written and spoken.
• Self-driven and able to work independently while managing workload effectively.

Nice to have

• Experience with agent frameworks, multi-step tool-use loops, or RAG systems at scale.
• Built or maintained an evaluation pipeline (offline evals, LLM-as-judge, human review loops).
• Open-source contributions, published writing, or talks on applied AI engineering.

On behalf of our client, we are looking for a Senior Full-Stack AI Product Engineer / AI Video Generation Engineer.

About the Project

An AI-powered web platform that helps businesses create animated explainer videos faster and at scale.

The product guides users through the full video creation workflow — from prompt and business context, to script generation, storyboard creation, video generation, and further editing based on user feedback.

The first goal is to launch an MVP/demo quickly using existing AI tools and APIs, with a longer-term vision of potentially building a proprietary AI video generation engine.

Responsibilities:

- Build an MVP of an AI-powered video generation platform

- Create user workflows for prompts, scripts, storyboards, video generation, and revisions

- Integrate AI models/tools/APIs for text, image/storyboard, and video generation

- Develop the web application structure, including landing page, subscriptions, payments, and user area

- Build or integrate an AI chat-style interface for video creation workflows

- Evaluate and select AI tools for fast MVP delivery

- Advise founders on technical feasibility, risks, and timelines

- Iterate on the platform based on feedback and product metrics

- Prepare architecture for future scalability and proprietary AI engine development

- Communicate technical decisions clearly to non-technical stakeholders

Requirements:

- 5+ years of experience in Full-Stack Product Development / MVP SaaS

- 2+ years of experience with AI / LLM integrations and AI workflow automation

- 1+ year of experience with Generative Media / AI Video or Image Generation

- Strong experience with React / Next.js or similar frontend frameworks

- Experience with backend APIs, authentication, payments/subscriptions, and web app architecture

- Experience with OpenAI / Claude / Gemini APIs

- Experience with prompt engineering and multi-step AI workflows

- Experience building AI chatbot logic, script generation, and content generation workflows

- Experience integrating third-party APIs and AI services

- Experience with tools/APIs such as Runway, Pika, Luma, Kling, Replicate, ComfyUI, Stable Diffusion, or storyboard-to-video workflows

- Experience building MVPs or early-stage products from scratch

- Ability to work independently and communicate directly with non-technical founders

- Strong English communication skills

Company offers:

- Long-term employment with possibilities for professional growth

- Fully remote work

- Reasonably flexible schedule

- 15 days of paid vacation

- Regular performance reviews

Product Engineer

AI-Enabled Products · Full-Stack · End-to-End Ownership
 Fully Remote (Europe preferred)
 Independent Contractor · 50–70% initially (ramping to full-time within 6–12 months)
 Reports to Founder & CEO

You’re Not a Cog. You’re the Engine.

Most engineering roles give you a ticket queue. This one gives you a product.

At Informed Decisions, you’ll take real ownership over how a meaningful B2B SaaS platform gets built- from architectural decisions to AI integrations to what ships on Friday. You’ll work directly with the founder, with real influence over technical direction, and you’ll see the impact of your work in how organizations hire and how people’s careers unfold.

If you’ve been waiting for a role where your judgment actually matters, this is it.

What We’re Building

Hiring is broken in ways most companies don’t even measure. Informed Decisions addresses this by combining IO psychology with data-driven product design- including statistical models, analytics, and AI-enabled capabilities- to make interviews fairer, more consistent, and truly predictive of on-the-job success.

We help organizations improve interviewer skills, reduce bias, and connect hiring decisions to real post-hire outcomes. The product is live, the problem is real, and the work is technically interesting.

What You’ll Own

This is a full-stack product engineering role. You’ll work across the system with .NET and Python on the backend, APIs and integrations, AWS infrastructure, and AI-enabled workflows embedded into real product features.

Your first major responsibility is taking full ownership of a live, production product- from database and backend services through APIs and application layers- currently developed with an external vendor. This includes deeply understanding what’s been built, identifying what needs to evolve, and establishing the engineering practices and standards that will carry the platform forward.

This is an active system with real users, real data, and real consequences. We’re looking for someone who can navigate this transition with technical rigor, sound judgment, and a strong sense of ownership.

On the product side, you’ll design and ship features end to end. That means writing the code, making architectural calls, defining what “done” looks like, and owning production quality.

On the AI side, you’ll build workflows that integrate LLMs and AI services into the product in ways that are reliable, observable, and grounded in measurable hiring outcomes.

Beyond the core platform, you’ll make judgment calls about when a customer need belongs inside the platform and when a standalone tool or application is the right answer- and then you’ll build it.

Engagement Model

This role starts as an independent contractor engagement, scoped at approximately 50–70% capacity.

The intent is to increase scope and ownership over time, with a planned ramp toward full-time (100%) involvement within 6–12 months, based on mutual fit, impact, and company needs.

You’ll Thrive Here If…

• You’ve shipped production systems and can show your work through code, products, or a real portfolio
  
   
• You’re comfortable owning decisions when there’s no one to escalate to
  
   
• You’ve worked with .NET and Python in real production environments
  
   
• You’ve integrated AI or LLM services into live products, not just prototypes
  
   
• Remote-first work suits how you operate- you create structure rather than relying on it
  
   
• Your English is fluent (spoken, written, and reading), strong enough to communicate technical decisions clearly across time zones
  
   

Experience with early-stage SaaS, third-party integrations, and complex systems is a strong advantage. The tradeoffs are real, and the work reflects that.

Why This Role, Why Now

• Direct line to the founder, with real influence on product direction
  
   
• Work tied to measurable outcomes: fairer hiring and better decisions
  
   
• A remote environment built on trust, not surveillance
  
   
• High ownership from day one across a technically deep and socially meaningful problem
  
   

How We Evaluate

We don’t screen on credentials. We evaluate based on what you’ve built and how you think. Come ready to show your work.
