Engineer, Experimentation Platform

About Woven by Toyota
Woven by Toyota is enabling Toyota’s once-in-a-century transformation into a mobility company. Inspired by a legacy of innovating for the benefit of others, our mission is to challenge the current state of mobility through human-centric innovation — expanding what “mobility” means and how it serves society.

Our work centers on four pillars: AD/ADAS, our autonomous driving and advanced driver assist technologies; Arene, our software development platform for software-defined vehicles; Woven City, a test course for mobility; and Cloud & AI, the digital infrastructure powering our collaborative foundation. Business-critical functions empower these teams to execute, and together, we’re working toward one bold goal: a world with zero accidents and enhanced well-being for all.

TEAM
Our team of experienced engineers is dedicated to simplifying and accelerating innovation for inventors and creators through a cutting-edge Experimentation Platform. We help inventors and aspiring inventors to test ideas and hypotheses in both digital and physical environments, leveraging A/B testing (among other kinds of experiments) to make the best data-driven decisions. By helping inventors to integrate experimentation into their product lifecycle, we help them ensure faster, better, and safer product releases. Our mission is to empower inventors by helping them bring their ideas to life through a structured, data-driven process. We are committed to developing a versatile platform that caters to the diverse needs of inventors, cultivating a culture of experimentation that minimizes risks, improves their product quality, and fuels their innovation.

• Expertise in building microservices architecture and working with containerization technologies (Docker and Kubernetes). Proficiency with relational and NoSQL databases (e.g., PostgreSQL, MongoDB, Redis)
• Experience with cloud platforms (preferably AWS) and modern DevOps practices (CI/CD pipelines, Infrastructure as Code using Terraform)
• Solid understanding of software security, performance optimization, and scalability in cloud environments
• Excellent communication skills and fluency in English, with a proactive approach to problem-solving

NICE TO HAVES:
• Hands-on experience with data processing frameworks/platforms (e.g., Spark, Flink, Daft, Databricks)
