Note: The job is a remote job and is open to candidates in USA. Keen Decision Systems provides an AI-driven marketing platform that empowers marketing leaders and finance teams to make data-driven, future-focused business decisions. The Senior Algorithms Engineer will develop, deploy, and improve algorithms for Keen AI Cortex, collaborating closely with the engineering team to enhance production code and model implementations.
Responsibilities
- Own algorithmic features end-to-end across the next generation of Keen's AI Cortex. Design, implement, test, ship, and watch them run in production
- Pitch in on adjacent Python backend projects (Django and FastAPI APIs, AWS infrastructure) when a piece of work spans more than one service
- Keep the engineering practices tight: code review, tests, CI gates, documentation, and a clean ticketed workflow
- Use AI coding tools with judgment. Fast iteration is the point. So is catching the moments when the model is confidently wrong
- Develop algorithms from business ideas and turn them into production code
- Collaborate with others in the development of the solutions, including the ability to effectively push back when the implementation can be improved
- Communicate clearly across Product, Research, and Engineering. Write the design doc, name the tradeoff, get the decision made
Skills
- 7+ years shipping production Python on a team
- Knowledge of inference methods, particularly in economics and business domains including time-series models (or more generally state-space modeling), probability modeling, and multivariate systems
- Comfortable with the engineering basics: tests, CI, code review, documentation, and working out of tickets
- Hands-on experience with AWS, Docker
- Operates independently. Scopes own work, talks to stakeholders, makes judgment calls when no one else is available to make them
- Writes and speaks clearly
- Math foundation in linear algebra, probability, and statistics. Demonstrated ability to read and write mathematical specifications, interpret and improve documented solutions
- Working knowledge of pandas and NumPy, with understanding of the use of these packages in implementing algorithms
- MUST be authorized to work in the United States. Keen is not able to provide sponsorship at this time
- MUST be able travel within the United States 1-3 times a year
- MUST have a reliable, everyday remote work desk station
- Marketing Mix Modeling (MMM) or another econometric background
- Bayesian inference experience
- Optimization exposure
- A track record of developing mathematical algorithms into shipped production systems
Benefits
- Mentoring and training from people who've been doing this for years
- Hands-on work on Bayesian models, optimization, and the data engineering behind them, applied to a product real customers use
- A seat in conversations across departments and at company-wide meetings
- 4-day work week with 3-day weekends
- Fully remote within the United States
