We're looking for someone who has been a tech lead before — someone who knows what it feels like to be the senior-most person in the room on a project, and who's comfortable both setting the technical direction and doing the hands-on design work personally when it counts. This role isn't purely about overseeing; you'll be initiating projects, personally designing systems and architecture, and then coordinating with other teams — data quality engineers, platform engineers, DevOps, product owners, and the business — to bring that design to life.</p> <p>Mentorship is a real part of the job, but it's not a replacement for staying technical. You'll grow other engineers through code review, guidance, and coaching, while remaining deeply hands-on yourself — someone others come to because you can actually do the work, not just talk about it. You'll also serve as the liaison between technical capability and business need, helping product and business stakeholders understand what's feasible while making sure technical decisions stay grounded in real business priorities.</p> <p><strong>Your day to day</strong></p> <ul> <li>Serve as the senior-most technical voice on projects you're part of, and act as the liaison between technical capability and business need — partnering with product managers and stakeholders to translate roadmap and customer priorities into technical direction, and translating technical realities back into terms the business side can plan around.</li> <li>Help shape the direction of our applied AI areas and intelligence features, driving deployment of state-of-the-art AI models and systems that directly impact Abacus's products and services (Abacus Agents, MCP, SQL and RAG agents and tools, and more).</li> <li>Develop novel data collection, fine-tuning, and LLM techniques, and design ML/AI pipelines for data preprocessing, feature engineering, model training, hyperparameter tuning, and evaluation — enabling rapid experimentation, iteration, and self-healing systems.</li> <li>Bu
