• Clear and constructive communication: you explain complex ideas clearly, make a strong case for your recommendations, and handle objections constructively.
• Pragmatism: you’re comfortable setting boundaries, pushing back on unrealistic expectations, and offering workable alternatives.
• Value orientation: when evaluating a solution, you consider client value, budget, timelines, risks, and the company’s interests.
• Transparency: you’re transparent about uncertainty and what needs to be validated before making commitments.
• Empathy: we value empathy, clear communication, and the ability to turn discussions into concrete agreements.

Experience that will help you succeed

Why this role

• High-impact involvement: an opportunity to apply your engineering expertise to business challenges, join the conversation from the start, influence the choice of solution, and help turn opportunities into viable projects.
• Great fit for consultants at heart: you’ll enjoy this role if client conversations, exploring options, and making the case for a solution interest you as much as architecture itself—and if success means a solution the client understands and the team can deliver.

About the Company

The company is a lean product team developing a consumer commerce platform that combines real-time 3D interactions with the purchase of physical products. The product also includes a real-money wallet and operational workflows for order processing and fulfillment. Their technology stack is built entirely around TypeScript. The engineering team is small and experienced, with engineers working closely with and reporting directly to the CTO, allowing for fast communication and decision-making.

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.

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

Business Development Manager (Middle / Senior) | Advertisers & Operators | iGaming CPA Network

We are looking for an experienced Business Development Manager to join an international iGaming CPA network.

Your primary responsibility will be identifying and acquiring direct advertisers, casino operators, and iGaming products, negotiating competitive commercial terms, and developing a profitable portfolio of offers.

We need a commercially driven professional with strong B2B sales skills who can independently manage the full business development cycle, from initial outreach and negotiations to integration, traffic launch, and account growth.

Priority GEOs: LatAm, Asia, MENA, Africa.

Responsibilities

• Identify and acquire direct advertisers, casino operators, and iGaming products for the CPA network.
• Establish relationships with decision-makers and manage the entire B2B sales cycle.
• Build and expand a portfolio of direct advertisers and competitive iGaming offers.
• Negotiate CPA, RevShare, and Hybrid agreements, including rates, caps, conversion qualification criteria, holds, and payment terms.
• Identify the affiliate team's demand for specific GEOs, traffic sources, and products.
• Coordinate advertiser onboarding, technical integrations, postback/API setup, and tracking verification.
• Work closely with Affiliate Managers to organize initial traffic tests and evaluate results.
• Develop existing advertiser relationships, negotiate higher caps and improved rates, and introduce additional GEOs and products.
• Monitor offer performance, conversion approval rates, traffic quality, and portfolio profitability.
• Participate in reconciliation processes, resolve payment discrepancies, and coordinate outstanding payments with the finance team.
• Maintain accurate CRM records, commercial forecasts, and launch pipelines.
• Represent the network at industry conferences and business events.

Requirements

• 2+ years of relevant Business Development, B2B Sales, or Advertiser Management experience in iGaming for Middle-level candidates; 3+ years for Senior-level candidates.
• Mandatory hands-on experience working on the CPA network or media buying side, personally sourcing and onboarding direct advertisers, casino operators, or iGaming products.
• Proven experience managing the full advertiser acquisition cycle: prospecting, negotiations, commercial agreements, integration, launch, and account development.

• Analytical mindset and experience working with CRM systems, commercial KPIs, and performance reports.

• English proficiency sufficient for independent international business negotiations, preferably B2 or higher.

What Matters Most

We are specifically looking for someone who has personally acquired and onboarded direct advertisers or iGaming products into a CPA network or media buying operation.

Experience exclusively selling services or products on behalf of a casino operator, without direct advertiser acquisition experience, does not meet the core requirements of this position.

The ideal candidate should be able to independently source advertisers, negotiate profitable deals, coordinate launches, and demonstrate measurable commercial results.
