 Tech Lead / Python AI Engineer / Engineering Lead / AI Architect.

Ideally, we would like to find someone based in Western Ukraine.

Across our practices, AI experimentation is organic: agents and accelerators get prototyped, they work, and they find their way to the teams who need them.

Working is not the same as dependable, tested, hardened, properly deployed, and fit for a regulated client. Closing that distance and turning experimentation into an engineering discipline is the job.

You will build and lead our AI engineering team: you, a Senior Engineer and a DevOps Engineer, and own the path from idea to production across every asset class.

You will work with SMEs within the practices to bring prioritised pilots into products that deliver return. You will be the final technical decision-maker on what ships. Roughly two-thirds of your week will be hands-on: architecture, coding and code review. The rest will focus on direction, hiring and the operating model.
 

Key Requirements

We are looking for someone who:

• Has strong experience building and owning products, rather than only completing technical tasks within outsourcing projects.
• Has 8+ years of engineering experience.
• Has strong Python experience, including production systems where Python was the primary language.
• Has strong Azure expertise and experience with production Azure workloads.
• Has hands-on experience with AI/LLM and agentic systems.
• Has experience taking products or platforms from architecture through production and ongoing operation.
• Has a player-coach background — able to lead engineers while remaining hands-on technically.
• Has strong English and communication skills.

Has experience working with regulated environments and implementing security/governance requirements in practice.

You will not be post-technical in this role.

• Responsibilities
• Own the AI delivery operating model and the path from prototype to production — from intake and qualification through build, hardening and rollout across accelerators and client-facing IP.
• Build and lead the AI engineering team: hire two engineers, set standards, review code, unblock the team and support their growth.
• Work with SMEs across practices to design, build, deploy and maintain applications.
• Personally build, ship and harden agentic solutions and own the assets you oversee.
• Own architecture and production standards across solutions, including solution architecture, infrastructure, model selection and validation.
• Turn governance into engineering through policy-as-code, guardrails, evaluations and release gates running in the pipeline.
• Implement controls suitable for regulated clients without unnecessarily slowing down development.
• Embed AI capabilities across practices by working with automation, application engineering and consulting SMEs to create a path from prototypes to production.
•  
• What Would Set You Apart?
• Claude Certified Architect (Foundations or Professional).
• Microsoft Agentic AI Business Solutions Architect (AB-100).
• LLM or agentic systems already taken to production.
• Experience deploying accelerators or productised IP across multiple clients.
• 
   

Location: Ukraine - preferably the western part of the country.

Budget: Up to €72,000 gross/year
 

Our client, a US healthcare nonprofit, is building a clinical application that turns AI-generated risk predictions into timely action. Frontline and clinical staff get alerts on their phones and tablets when a participant is identified as being at elevated risk. They can review the participant's recent history and record the actions they took, while supervisors monitor follow-ups and manage escalations.

The product handles protected health information (PHI), runs on Microsoft Azure and is built with an AI-first approach, so you'll use AI coding tools as part of your daily workflow.

Engagement

• Start: ASAP
• Duration: up to 4 months, with a possible extension for ongoing support
• Month 1, discovery phase: up to 60 hours
• Months 2 to 4, development phase: full-time, about 160 hours per month
• Working hours: Mon to Fri, with at least 4 hours of overlap with the team's 9:00 to 17:00 EST

Must-have skills

• Experience: 5+ years of commercial full-stack development
• Back end: C#, .NET, ASP.NET Core Web API, Entity Framework Core, PostgreSQL, REST API design and development
• Front end: TypeScript, React.js, Vite and Tailwind CSS; responsive, mobile-first interfaces; accessibility standards (WCAG)
• Security: authentication and authorization with OAuth2 / OpenID Connect and SSO
• Quality: automated unit, integration and end-to-end testing; Git and CI/CD workflows
• AI-assisted development: hands-on daily use of tools such as Claude, Codex or similar
• English: upper-intermediate or higher

Nice to have

• Healthcare or another regulated industry, particularly HIPAA requirements
• Progressive web apps (PWA) and offline-first solutions
• Microsoft Azure

Hiring process

1. HR interview.
2. Technical interview with the team.
3. If needed, a final conversation to align on the last details.

  Ability to build processes around you: you set up workflows with performance managers, designers, align priorities, and make the collaboration run smoothly

  Proactivity: when something doesn’t work, you see the problem, suggest a solution and implement it yourself

DOIT Software is looking for an AI/ML Engineer to join the engineering team of a B2B SaaS product company and build machine learning and AI features into its platform.

About the Client

Our client is a SaaS product company working in analyst relations (AR) and B2B influencer relations. Its platform helps technology vendors and B2B companies manage, track, and measure their relationships with industry analysts who influence buyers in the market.

The product combines a specialized CRM with a searchable database of analysts and influencers, analytics and reporting dashboards (share of voice, sentiment, competitive intelligence), and an analyst-facing self-service portal.

About the Role

You will design Python-based models and services, integrate large language models (Anthropic’s Claude), and ship them alongside the client’s software engineering team.

The platform runs on Angular, C# (.NET), SQL Server and MongoDB. You will not be the primary developer on that stack, but you will work in it daily: pulling data from it, exposing your models to it through APIs, and pairing with engineers to get AI features into production.

You will report to the VP of Engineering. This is a full-time, fully remote position that requires at least 3-4 hours of daily overlap with US Eastern Time for standups and pairing.

What You’ll Do

Machine learning and data science

• Design, train, evaluate and deploy ML models for classification, clustering, recommendation, NLP and forecasting use cases.
• Explore, clean and engineer features from product data stored in SQL Server and MongoDB.
• Define metrics, run experiments and report results clearly to engineering and product stakeholders.
• Monitor models in production for drift, accuracy and cost, and retrain as needed.

AI and Claude integration

• Build LLM-powered features using the Claude API: prompt design, tool use, structured outputs and retrieval-augmented generation (RAG).
• Develop evaluation sets and automated tests to measure LLM output quality, accuracy and safety.
• Optimize LLM usage for latency and cost (prompt caching, model selection, batching).
• Use AI coding assistants such as Claude Code to speed up your own development work.

Working with the product engineering team

• Package models and AI logic as Python services and REST APIs that the C# (.NET) backend calls.
• Work with Angular developers to shape how AI features appear and behave in the UI.
• Write efficient SQL Server queries and MongoDB aggregations, and help design schemas for the data that ML features need.
• Take part in code reviews, sprint planning and standups, following the team’s Git, CI/CD and testing practices.
• Document models, data pipelines and APIs so other engineers can support them.

Required Qualifications

• 3–5 years of professional experience in data science, ML engineering or a similar role.
• Bachelor’s degree in Computer Science, Data Science, Statistics, Mathematics or a related field, or equivalent experience.
• Strong Python skills, including pandas, NumPy and scikit-learn.
• Hands-on experience with at least one deep learning framework (PyTorch or TensorFlow).
• Solid understanding of ML fundamentals: supervised and unsupervised learning, feature engineering, model evaluation and avoiding overfitting.
• Practical experience building with LLM APIs, ideally Anthropic Claude: prompt engineering, tool use, RAG and output evaluation.
• Experience building and consuming REST APIs in Python (FastAPI or Flask).
• Working knowledge of SQL (SQL Server preferred) and a NoSQL document database (MongoDB preferred).
• Comfortable with Git, code reviews and Agile/Scrum workflows.
• Clear written and spoken English (Upper-Intermediate or higher) for daily collaboration with a distributed team.
• Proactive written communication: status updates, clear questions and documented decisions.
• Ownership of features from prototype to production, not just notebooks.
• Curiosity about new AI capabilities and the judgment to know when a simpler approach is better.

Nice to Have

• Experience with vector databases or embedding search (e.g., MongoDB Atlas Vector Search, pgvector, Pinecone).
• Familiarity with agent frameworks, the Model Context Protocol (MCP) or the Claude Agent SDK.
• Reading-level familiarity with C# / .NET and Angular / TypeScript, enough to trace how your services are called.
• MLOps experience: Docker, CI/CD pipelines, model versioning (MLflow or similar) and cloud deployment (Azure or AWS).
• Prior work on a multi-tenant B2B SaaS product.
• NLP work on unstructured business text such as documents, emails or research content.
• Understanding of data privacy and security practices for customer data used in AI features.

Recruitment Process

1. Pre-screen call with a Recruitment Manager.
2. Technical interview with DOIT Software.
3. Online call with the client.
