ABOUT THE ROLE

As our Senior Customer Success Engineer you will combine technical expertise with customer empathy to deliver world-class support across the entire customer journey.

The role is not just about troubleshooting. From the implementation to ongoing support and ticket resolution, you will own the technical customer relationship. You will triage, debug and resolve issues and when needed you are also able to ship fixes or implement small features. All the while looking to delight our customers and create an incredible experience for them.

Think of yourself as the customer-arm of the engineering team bringing technical expertise to the frontlines of client interactions.

TEAM INTEGRATION

• You report to the CTO with a dotted line to the Customer Success Manager

• You collaborate closely with Product and Engineering to coordinate issue resolution, escalation, and product improvements.

ROLE OBJECTIVES

You are successful if you:

• Develop deep product expertise and confidently guide customers through complex issues and workflows.

• Own cases end-to-end — from first report to resolution — within SLA times, clear updates, and consistent follow-through.

• Shield engineering teams from daily flow of customer requests, while still ensuring customer needs are met with urgency and accuracy.

• Implement smaller bug fixes, patches, and customer-requested enhancements where possible.

• Translate customer conversations into structured, actionable engineering work (more major bug reports, feature requests, investigations).

• Work with the engineering team on the implementation of the feature requests from customers and bug fixes.

• Create tutorials, customer walkthroughs, and step-by-step enablement content when needed to prevent repeat issues.

• Keep support operations clean and predictable through disciplined use of Pylon, Linear, and internal triage workflows.

ROLE REQUIREMENTS

• Solid experience in a technical support, customer-facing engineering, or solutions engineering role.

• Solid engineering background with hands-on experience across modern backend/web stacks (APIs, auth, networking, observability).

• Strong debugging skills and confidence navigating complex systems.

• Excellent written communication, you can explain technical concepts clearly and calmly, without losing technical detail.

• Proven ability to handle support volume with strong prioritization and time management.

• Experience working with ticketing tools such as Zendesk/Pylon or Jira/Linear.

• Ability to work independently, take ownership, and drive issues to resolution.

• Strong documentation habits: you write things down, keep them updated, and make them easy for others to use.

• Experience supporting high-profile or high-scale customers in shared channels (Slack Connect setups).

• Ability to write small scripts or automation to speed up debugging or reduce repetitive work.

• Knowledge of APIs, GraphQL, TypeScript/Node.js, databases, or cloud environments.

WHAT SUCCESS LOOKS LIKE

This role’s outcomes include:

• Customers feel supported, unblocked, and confident — even when things go wrong.

• Bugs and small feature requests are handled quickly, either via direct fixes or well-prepared escalations.

• Support is fast, high-signal, and predictable, with excellent communication throughout.

• Incoming noise is filtered and organized. Developers stay focused on delivery instead of customer firefighting.
