The Job At-A-Glance: Join a fast-growing AI engineering team building the next generation of intelligent products for the financial services industry. As a Machine Learning Engineer, you'll design and deliver production-ready AI solutions, develop the tools, APIs, and backend services that enable them, and help shape the future of our AI platform. From evaluation frameworks, deployment pipelines, and microservice-based AI capabilities to next-generation agentic workflows, you'll have the opportunity to work across the stack, prototype new ideas, and turn innovation into real customer value. We're looking for engineers who are passionate about technology, committed to building high-quality, enterprise-grade software, and who thrive in collaborative environments. The ideal candidate stays current with the rapidly evolving AI landscape, enjoys solving meaningful problems, and is excited to help build innovative solutions alongside a team that values creativity, ownership, continuous learning, and shipping great products. A Typical Day: Build, test, and optimize production-ready LLM agents leveraging multi-step reasoning, prompt engineering, retrieval, memory, and tool-calling capabilities. Develop scalable evaluation pipelines (Evals) to continuously measure accuracy, task completion, latency, cost efficiency, safety, and hallucination rates. Integrate agentic workflows with external platforms, vector databases, microservices, MCP, and internal APIs to enable reliable context retrieval and automated action-taking. Fine-tune domain-specific LLMs using modern adaptation techniques like supervised fine-tuning (SFT), LoRA/PEFT, and preference optimization to maximize performance. Productionize AI services across cloud and backend architecture, implementing security guardrails, observability, and robust deployment pipelines. Track prod…
