We are hiring a Senior Backend Engineer for its Customer Focus Group (CFG) — a technical team that bridges engineering and the commercial side of the product. CFG members handle development, architecture, product, and direct customer interaction: translating customer needs into the product, building new features, and resolving pressing technical issues. The role needs a strong backend builder who can also take a holistic, product-and-customer view, with a focus on infrastructure, performance, and customer satisfaction.

• Backend architecture — microservices, API design, and design patterns (deep understanding)
• Node.js / TypeScript proficiency (or other relevant backend languages)
• SQL and NoSQL databases, with experience scaling systems for high-volume data processing
• Cloud platforms (AWS, Azure, or GCP) and their services — serverless computing, managed databases
• 5+ years of backend development, with a strong focus on customer-centric products
• Proven problem-solving with a track record of performant, scalable solutions
• Agile development practices and CI/CD pipelines
• Excellent collaboration and communication with globally distributed teams

Nice-to-have skills:

• Security / AppSec domain familiarity (OX is a security product)
• Customer-facing / pre-sales technical experience
• Experience bridging product and engineering
