Why This Role is Exciting We are looking for a Senior Software Engineer with strong machine learning experience to help build and scale intelligent, production-grade systems that power our risk and compliance platform. In this role, you’ll work at the intersection of software engineering and applied machine learning, shipping real customer-facing features that leverage both classical ML techniques and modern approaches like Large Language Models (LLMs). You’ll be embedded in a product engineering team, owning systems end-to-end—from API design and data pipelines to model integration, evaluation, and long-term maintainability. If you enjoy building robust software systems and applying ML pragmatically (not experimentally) to solve real customer problems, this role is for you. RESPONSIBILITIES - Design and implement AI-powered systems using a mix of classical ML techniques and modern LLM-based approaches, frequently leveraging managed Azure AI/ML services as building blocks. - Apply a range of techniques—from classical ML to LLM-based approaches (RAG, prompt engineering, fine-tuning, semantic search)—with a strong focus on reliability, performance, and maintainability - Collaborate closely with product managers and designers to deliver high-quality, customer-focused features. - Write clean, testable, well-documented code and contribute to shared engineering standards. - Author clear design docs that explain system behavior, tradeoffs, and long-term implications. - Debug and resolve production issues across application code, data, and ML components. - Evaluate ML systems using metrics and real-world signals, and iteratively improve them. - Participate fully in an Agile development lifecycle, contributing to planning, reviews, and retrospectives. - Stay current on ML and software engineering best practices, adopting new tools thoughtfully and pragmatically. ATTRIBUTES OF A SUCCESSFUL CANDIDATE: - Bachelor’s or Master’s degree in Computer Science, Engineering, Mathematics, or a related field—or equivalent practical experience. - 4+ years of professional software engineering experience, with meaningful exposure to machine learning in production systems. - Strong ability to design and build scalable, production-quality software. - Excellent programming skills in Python - Hands-on experience applying machine learning models in real systems, including model integration, inference, and evaluation. - Familiarity with ML frameworks such as PyTorch, TensorFlow, Hugging Face, or scikit-learn. - Experience or interest in search, information retrieval, ranking, or recommendation systems. - Product mindset: you care about user impact, not just technical elegance. - Strong communication skills and comfort working cross-functionally. PREFERRED - Experience with Node.JS and TypeScript - Experience working on SaaS web applications - Basic understanding of distributed systems - Bonus: Docker, Kubernetes experience, AWS/Azure cloud infrastructure Our Company Values - Customer obsession: It starts and ends here. Consistently ask yourself how what you’re doing creates value for our customers. It’s a mindset. - Gritty resilience: Make it happen. Find a way. Move fast, stay positive, and do what it takes. - Drive innovation: Create the future. Continuously improve what exists and invent what’s next. - Win, together: One team. No silos, no egos. Drive to be the best and support each other’s success. - Growth mindset: 10x, not 10%. Think in orders of magnitude, not increments. Seek feedback, learn, and improve.
