As a Senior Python Software Engineer, you will design, build, operate, and scale the technical platforms, services, and tools that support the entire machine learning lifecycle. You will create the foundation for data collection, model training, deployment, and operations, working at the intersection of software engineering, data platforms, MLOps, and machine learning.

The primary focus of this role is the development of production-ready software solutions, platforms, and workflows. Day-to-day responsibilities will mainly involve software development, architecture, automation, and system integration, rather than training machine learning models.

Typical tasks span:

Machine Learning Engineering

Build end-to-end ML training pipelines (ingestion, validation, transformation, training, evaluation)

Deploy, optimize and package models for inference

Support the platform team to serve models in cloud

Support the ai runtime team to serve models on edge/sorters

Participate in data and model centric research and innovation

Data Management

Build, integrate and maintain secure data platforms (e.g., SQL/NoSQL warehouses, object storage, feature stores)

Ensure data security, privacy, and compliance

Service & ML Tooling

Design and implement REST APIs to expose ML services and data platform functionality

Develop and maintain internal tools and web-based UIs that support ML workflows

Software Engineering

Apply software engineering practices for version control, code reviews, and accurate technical documentation

Develop robust and maintainable code with unit, integration, and performance tests and knowledge transfer

Containerize components and implement CI/CD pipelines

Maintain and troubleshoot ML tooling in production

Close collaboration and alignment with our internal users

We expect high ownership of assigned projects including stakeholder management, requirements engineering, project management and technical decisions.

Several years of proven professional experience delivering production ML systems with measurable impact

Expertise in Python

Expertise in computer vision and ML/DL tooling

Proficiency in MLOps: data modelling, packaging, containerization, CI/CD

Proficiency in data science for vision-based model optimization

Knowledge with (or willingness to learn) TypeScript, REST API development, and modern frontend frameworks (e.g., Vue.js, React)

Knowledge in cloud and on-prem platform and interfaces

Knowledge in model optimization frameworks (TensorRT, ONNX, CUDA, cuDNN) and edge deployment on hardware (x64, ARM/Jetson)

What to Expect

Modern technologies and AI-driven systems

A hands-on engineering environment with direct impact on machine performance

Close collaboration with international teams

Informal culture with low hierarchies and short decision paths

Norwegian company culture with an open “you” mentality

Opportunity to actively shape future machine developments

What We Offer

Hybrid working model

Flexible and international working environment

Modern office and testing facilities

Sustainable and future-oriented industry

Competitive salary package including bonus

Laptop and mobile phone
