AI Software Engineer

Numerator is looking for a passionate AI Software Engineer to join our growing Machine Learning team . This is a unique opportunity where you will get a chance to work with an established and rapidly evolving platform that handles millions of requests and massive amounts of events, and other data. In this position, you will be responsible for taking on new initiatives to design, build, deploy, and support high performance deep learning systems in a rapidly-scaling environment.
As a member of our team, you will make an immediate impact as you help build out and expand our technology platforms across several software products. This is a high growth and impact role that will give you tons of opportunity to drive decisions for projects from inception through production.
How You'll Spend Your Time:

• Apply agentic LLM patterns (tool use, multi-step reasoning, orchestration) to automate high-complexity tasks that previously required human judgment
• Design and build GenAI-powered solutions for complex NLP tasks - NER, classification, information retrieval, summarization, and structured output generation
• Build and maintain production ML APIs and data pipelines that deliver model-driven automation and insight into Numerator's products at scale
• Work closely with MLOps engineers, product & engineering managers, and other teams, owning a large part of the process from problem understanding to shipping the solution.
• Stay current with the fast-moving GenAI landscape and translate new capabilities into practical team impact

Skills & Requirements
What You'll Bring to Numerator

• 2+ years of experience building and deploying ML or GenAI systems in production
• Strong practical GenAI fundamentals: LLM APIs, context engineering, RAG, tool/function calling, skills, agents and evaluation methodology - you understand why these techniques work, not just how to call them
• Data acumen: you can critically assess a dataset, spot distribution problems, and reason about how data quality affects downstream model and business outcomes
• Product orientation: you engage with business context naturally, ask the right clarifying questions, and translate ambiguous requirements into well-scoped technical solutions
• Solid Python and software engineering fundamentals - clean, testable code, REST API design, debugging, and familiarity with CI/CD
• A genuine habit of self-improvement - you follow the field actively, experiment with new models and tools, and bring what's relevant back to the team

Extra, Nice to haves

• Experience with agentic orchestration frameworks
• Fine-tuning experience with modern techniques - especially applied to domain adaptation for NLP tasks
• PyTorch or Hugging Face familiarity
• Familiarity with LLM evaluation frameworks and a structured approach to measuring model quality
• Inference optimization awareness - understanding latency/cost/accuracy tradeoffs for LLM solutions
• Experience building and deploying robust machine learning APIs in production environments (ideally cloud-based environments such as AWS or GCP)

What We Offer

• An inclusive and collaborative company culture- we work in an open environment while working together to get things done, and adapt to the changing needs as they come.
• Market competitive total compensation package.
• Volunteer time off and charitable donation matching.
• Strong support for career growth, including mentorship programs, leadership training, access to conferences and employee resource groups.
