We are committed to transparency and fairness in our hiring process and welcome conversations about compensation throughout the recruitment process.
What You’ll Get To Do
This posting is for a current vacancy within our software team.
We are looking for a rigorous, delivery-focused Machine Learning Developer with 3 or more years of experience who thrives at the intersection of software development and machine learning models to join our team and help us build, optimize, and deploy the next generation of our predictive models.
In this role, you will be responsible for designing, training, and validating machine learning models that analyze complex hyperspectral data streams in real time. Because our systems operate inline on active food production belts, you must possess an exceptional attention to detail to ensure accuracy, and a relentless delivery focus to get models out of the lab and into the field. Working within an Agile framework, you will collaborate with software and data teams to build robust, repeatable pipelines that scale. Preference will be given to software developers who have developed or want to develop machine learning models, over data scientists who have not shipped to production.
In This Role, You Will Work On
- Develop ML Systems: Design, build, and scale machine learning algorithms and data pipelines from prototype to production. Perform real-time classification, segmentation, and regression tasks on hyperspectral imaging data.
- Software Engineering: Apply software best practices, including coding standards, testing, code reviews, and source control management.
- Feature Engineering: Extract, analyze, and optimize features from high-dimensional spectral datasets, ensuring models remain highly performant under strict real-time processing constraints.
- Clean Code Architecture: Write clean, maintainable, and well-tested code, ensuring that ML components seamlessly integrate with PPO’s broader software ecosystem.
- AI-First Workflow: Embrace an AI-first mindset, actively utilizing generative AI programming tools to optimize your workflow, automate routine scripting, and accelerate engineering velocity.
- Rigorous Validation: Collaborate with Data Scientists to apply statistical validation metrics to ensure model accuracy, safety, and generalization across diverse customer operational environments.
- Delivery-Focused Execution: Employ continuous delivery approaches to support iterative delivery of model enhancements, ensuring deadlines are met without compromising on quality or system stability.
- CI/CD Integration: Work closely with MLOps and DevOps to integrate model training, testing, and deployment into automated CI/CD pipelines, treating models with the same rigorous versioning and testing standards as traditional software.
- Agile Collaboration: Actively participate in daily standups, sprint planning, and retrospectives, working within Agile methodologies to maintain team velocity and cross-functional alignment.
You at PPO
What You Bring
- Minimum of 3 years of professional experience as a software developer, with concrete examples of working on machine learning.
- Mastery of Python and its scientific ecosystem (e.g., NumPy, SciPy, Pandas, Scikit-Learn). Preference given to experience with deep learning frameworks such as PyTorch or TensorFlow.
- Proven ability to handle messy, high-dimensional real-world sensor data, identifying edge cases and data anomalies that could impact production model performance.
- Experience with version control (Git), containerization (Docker), and automated testing/deployment pipelines (CI/CD tools like GitLab CI, GitHub Actions, or Jenkins).
- Experience working in structured Agile/Scrum environments, with the ability to break down complex ML research tasks into manageable sprint deliverables.
- Bachelor’s or Master’s degree in Computer Science, Engineering, Mathematics, Physics, or a related technical field.
