ABOUT CORDIAL
We founded Cordial in 2014 on the belief that there should be more humanity and empathy in marketing—both in how brands communicate with their customers and in how technology companies work with brands. We built our company and platform purposefully, driven by a desire to inspire more thoughtful communication and to create experiences that feel more personal and human—for consumers, for the people at the companies we work with, and for Cordial employees. Today, brands like PacSun, Revolve, Abercrombie & Fitch, Realtor.com, L.L. Bean and Forbes rely on Cordial to drive revenue growth by sending a better message.
We chose the name Cordial to symbolize how we empower our clients to communicate with their customers, as well as how we do business: with transparency, collaboration, and trust. We're building a passionate team of individuals willing to learn, grow, and be thoughtfully challenged on a daily basis to continuously improve our product, company, and culture every single day.
OUR VALUES
- Communicate better than the rest
- Own it, every time
- Solve client problems tenaciously
- Make Waves
Role Overview
We are looking to add a Data Scientist – Production Engineering to our data science team. This role focuses on operationalizing, optimizing, and scaling data science models and systems that are already in production or transitioning into production.
Our data science work extends beyond traditional machine learning and includes statistical models, optimization logic, heuristics, rules-based systems, ML and LLM models, all operating on large, real-world datasets. This role is designed to strengthen the implementation and performance side of our data science stack while working closely with data scientists, engineering and product teams. This role requires someone who can ramp up quickly, work independently, and contribute meaningfully without extensive onboarding.
Key Responsibilities
- Optimize existing data science models and systems for performance, scalability, and reliability
- Translate research-grade or prototype data science code into production-ready implementations
- Work with large datasets and improve efficiency related to memory usage, runtime, and compute cost
- Contribute to and maintain production data pipelines and workflows.
- Collaborate closely with other data scientists to preserve model intent, correctness, and assumptions while improving implementation quality
- Debug and resolve issues in production or near-production data science workflows
- Improve robustness, monitoring, and maintainability of deployed models and pipelines
- Support iterative model improvements and system evolution as business needs change
Required Experience & Qualifications
- Bachelor’s degree or higher in Data Science, Computer Science, Statistics, Mathematics, or a related quantitative field, plus 3+ years of experience working with real-world, industry, or production data in a data science, applied ML, or analytics role
- Demonstrated experience contributing to production data science or analytics systems, not only exploratory or academic projects
- Strong programming skills in Python and experience writing maintainable, production-quality code
- Experience working with large datasets and performance-sensitive workflows
- The code word is #becordial
- Prior experience with data pipelines and orchestration frameworks (e.g., Dagster, Airflow, etc.)
- Cloud platform expertise, particularly AWS services (Glue, Athena, ECS, S3 Tables, etc.) for scalable data processing and model deployments
- Hands-on experience with modern data warehouse solutions (Snowflake, BigQuery, etc.) including query optimization, clustering strategies, and cost management
- Experience with big data technologies and distributed computing frameworks for handling enterprise-scale event datasets
- Solid understanding of data science fundamentals, including statistics and modeling concepts, sufficient to work closely with research-oriented data scientists
- Ability to work independently and ramp up quickly in an existing codebase and system
- Experience working in small, fast-moving teams where ownership and autonomy are expected
COMPENSATION & BENEFITS
$140,000.00 - $175,000.00 base salary annually. The compensation range may be adjusted based on experience and location. In combination with base salary, Cordial's compensation package includes equity and bonus, a robust benefit plan (medical/dental/vision/life), 401k match, flexible time off and paid company holidays. Additionally, we offer perks such as an annual company conference, childcare and continued education yearly reimbursements. We pride ourselves in maintaining a healthy work/life balance, a strong dedication to DE&I efforts, and an overall respectful and open culture!
