• Ability to manage multiple projects simultaneously

• You prefer having detailed specifications before starting work.
• You dislike operational problem solving.
• You don’t enjoy talking to customers.
• You expect every day to be predictable.

You’ll probably enjoy this role if

Join our team — it's going to be hotter than you can imagine.

We are against all types of discrimination, bullying, and stereotypes. We provide equal employment opportunities regardless of race, skin color, religion, gender, sexual orientation, gender identity, age, marital status, health status or any other characteristics.

Are you energized by walking into a client’s operation, finding the workflow that’s actually holding them back, and rebuilding it so AI handles the parts that don’t need a person? At Sigma Software, we don’t just add AI on top of existing processes  we redesign how the work gets done, with AI built into the operating logic from day one.

We’re looking for a Forward AI Deployment Engineer to own that redesign end to end: embedded with the client, hands-on with whatever automation the workflow actually needs, and accountable for turning a real operational problem into something running in production not a demo, not a pilot. Each engagement is built to leave something behind for the next one patterns, infrastructure, governance that already held up in production  so the second engagement doesn’t start from zero, and the tenth looks nothing like the first.

Requirements

• Proven experience taking AI systems from prototype to production inside a real operating environment, not just in a lab or sandbox.
• You treat LLM/RAG architectures, agentic systems, cloud platforms, and data pipelines as tools for redesigning how work gets done, not as the deliverable — and you’re strong and current enough with all of them to actually use them that way.
• Comfort mapping decision logic that’s partly undocumented, and judgment about where automation should stop and human accountability should start.

• Excellent communication and stakeholder management — able to advise a client directly and escalate without being asked.

   

  Responsibilities

   

• Embed directly with the client’s operational team to find the workflow that’s actually costing them time, quality, or money before recommending any tooling.
• Own the redesign end to end: rework the decision flow and handoffs around AI, then take the resulting system into production yourself.
• Translate a vague, cross-functional business problem into a concrete technical plan the client’s team can actually execute against.
• Prototype fast enough to show the client what’s possible, then build only the parts of that prototype the redesigned workflow actually needs.
• Where the redesign calls for it, build the agentic systems, RAG pipelines, or custom data pipelines that make it real never a deliverable in itself, always because the workflow needs it running in production.
• Manage stakeholder alignment across the client’s org, escalating early and requesting support before a blocker becomes a delay.
• Build up the client’s own team alongside the system pair with their people, explain the reasoning behind each decision, and leave them able to run and improve what you built after you’ve moved to the next engagement.
• Build the feedback loop from day one  telemetry, evaluation pipelines, human-in-the-loop review — so the system keeps improving after you’ve moved on.

ENIOR FULLSTACK & AI/ML ENGINEER

We're looking for a Senior Fullstack & AI/ML Engineer to implement AI solutions that automate operational business processes. We need someone who can own solutions end-to-end — from prototype and architecture through production — and is responsible for the full product stack: UI, backend, data, and the AI layer.

IIN THIS ROLE YOU WILL

1. Develop frontend interfaces in React for client products and internal tools.
2. Design, build, and maintain backend services, REST APIs, webhooks, and third-party integrations in Node.js/TypeScript and/or Python; design ETL pipelines.
3. Design, build, and optimize ML models for real business problems.
4. Develop and integrate AI solutions based on GPT, Claude, and Gemini into production applications.
5. Build AI assistants and solutions for intelligent automation of document processing (structured extraction, OCR), application verification, customer support, and other business processes.
6. Design and implement Retrieval-Augmented Generation (RAG) solutions and agentic workflows.
7. Integrate solutions with ERP/CRM and corporate systems.
8. Work with PostgreSQL/Supabase, MongoDB, and vector databases (Pinecone, Weaviate).
9. Develop and maintain asynchronous tasks (Celery); work with Docker, Redis, and CI/CD pipelines.
10. Evaluate and improve AI model performance through experiments, A/B testing, and results analysis.
11. Deploy and maintain solutions in production — monitoring, troubleshooting, fixes, and ongoing development.
12. Make architectural decisions and set technical standards.

What we're looking for:

• 3+ years of commercial React development experience (production-level).
• 3+ years of commercial experience building AI/ML solutions (NLP, LLM).
• 1.5+ years of hands-on experience integrating LLMs into production.
• Practical experience with LLM APIs (OpenAI/Anthropic/Google), structured outputs, function calling / tool use, RAG.
• Experience with prompt engineering and frameworks such as LangChain / LangGraph / LlamaIndex.
• Experience with structured extraction from documents and free-form text (contracts, reports, correspondence).
• Experience building stateful pipelines with state tracking in a database.
• Experience with PostgreSQL / Supabase and MongoDB.
• Experience integrating with ERP/CRM or other corporate systems.
• Hands-on experience with Docker, Git, Redis, Celery, and CI/CD.
• Experience deploying and supporting production systems (monitoring, troubleshooting).
• Ability to both build architecture from scratch and independently navigate existing code, extending it safely without breaking production logic.
• Strong understanding of software architecture, clean code principles, and SOLID.
• English: Upper-Intermediate (B2) or higher.
• Native Ukrainian.
• Bachelor's or Master's degree in Computer Science, Applied Mathematics, Data Science, or a related field.

Nice to have:

• Experience with AWS, Azure, or Google Cloud Platform (including SageMaker, Bedrock, or Azure OpenAI).
• Experience with microservices and Kubernetes.
• Experience deploying to client environments (self-hosted solutions, not only shared cloud).
• n8n / Make or similar automation platforms.
• NumPy/Pandas for data processing.
• Fine-tuning open-source models (LLaMA).
• Familiarity with automated testing.

• Experience building internal enterprise systems.

  Experience working with sensitive client data and selecting an LLM provider based on data processing requirements (DPA) is a plus.

   

Engagement format: project-based / part-time / full-time — to be discussed depending on scope and workload.

• To be considered for this role, you must be able to work under the FOP (sole proprietor) model.

Key Requirements:

- At least 4 years with .net

- At least 2 years of on-hands experience with Umbraco 8 , 9 , 10 versions
