Senior Support Engineer, EU

At Sanity.io, we’re building the future of AI-powered Content Operations. Our AI Content Operating System gives teams the freedom to model, create, and automate content the way their business works, accelerating digital development and supercharging content operations efficiency. Companies like SKIMS, Figma, Riot Games, Anthropic, COMPLEX, Nordstrom, and Morningbrew are using Sanity to power and automate their content operations.

We’re looking for an empathic senior support engineer who thrives on solving complex technical challenges and helping customers succeed with Sanity at scale.

As a senior member of the team, you will independently own high-impact issues, guide enterprise customers through complex implementations, and improve the systems, workflows, and documentation that power our support organization.

This is not a reactive ticket-queue role. It requires strong technical judgment, calm communication under pressure, and the ability to turn recurring customer friction into lasting improvements.

What you would do:- Independently own and resolve complex technical issues for enterprise customers.

• Lead investigations into ambiguous or high-severity issues and liaise during incidents, maintaining clear communication throughout.

• Produce high-quality minimal reproductions, reusable code snippets, and structured issue reports.

• Provide informal mentorship and technical guidance to other Support Engineers, helping the team navigate complex issues and continuously improve how we investigate, communicate, and resolve problems.

• Collaborate closely with Product and Engineering to surface patterns and influence product improvements.

• Author and improve documentation, guides, and self-serve resources to reduce recurring issues.

• Contribute to infrastructure, tooling, and workflow improvements within the Support organization.

• Participate in community support rotation and model high standards of clarity and empathy.

• You'll own issues end-to-end, including a paid on-call rotation for high-severity production incidents.

About you:- Remote in the UK or Ireland

• 4+ years of hands-on experience in developer support or engineering roles.

• Strong experience debugging complex JavaScript/TypeScript and modern web applications (e.g., Next.js).

• Demonstrated success in independently owning complex issues from diagnosis to resolution.

• Ability to elevate those around you through thoughtful collaboration, clear communication, and informal mentorship.

• Comfortable operating under pressure while maintaining clarity and empathy.

• Strong debugging instincts and ability to reason across frontend, APIs, and infrastructure layers.

• Bias toward improving systems, documentation, and processes rather than just resolving individual support requests.

• Curious, proactive, and energized by solving ambiguous problems.

What we can offer:- A highly-skilled, inspiring, and supportive team

• Positive, flexible, and trust-based work environment that encourages long-term professional and personal growth

• A global, multi-culturally diverse group of colleagues and customers

• Comprehensive health plans and perks

• A healthy work-life balance that accommodates individual and family needs

• Competitive salary and stock options program
