Technical Support Engineer L3 information

What are the roles and responsibilities of a Technical Support Engineer L3?

A Technical Support Engineer L3, also known as Level 3 support, is responsible for handling the most complex technical issues that cannot be resolved by lower-level support teams. They work closely with engineering and development teams to diagnose, troubleshoot, and resolve advanced technical problems, often involving deep system analysis and debugging. L3 engineers may also create documentation, provide mentorship to junior staff, and help implement long-term solutions to recurring issues. Their role is critical in ensuring customer satisfaction and system stability.

What skills and qualifications are needed to thrive as a Technical Support Engineer L3?

To thrive as a Technical Support Engineer L3, you need advanced troubleshooting abilities, deep knowledge of operating systems and networks, and typically a degree in computer science or a related field. Familiarity with ticketing systems like ServiceNow, diagnostic tools, scripting languages, and relevant certifications such as CompTIA, Microsoft, or Cisco is important. Strong analytical skills, clear communication, and patience help you stand out when resolving complex issues and guiding less experienced team members. These skills ensure high-level problem resolution, customer satisfaction, and efficient escalation management in demanding technical environments.

What are typical challenges faced by a Technical Support Engineer L3, and how can they be managed effectively?

Technical Support Engineer L3s often encounter complex and escalated issues that require advanced troubleshooting and deep product knowledge. One common challenge is managing multiple high-priority cases simultaneously while maintaining effective communication with both customers and internal teams. Successfully handling this role involves strong time management, staying updated on technical developments, and collaborating closely with engineering and product teams to resolve persistent problems. Building strong relationships with customers and providing clear, proactive updates is also key to ensuring a positive support experience.

Job description

This position is listed on behalf of a partner company, who manages all applications and next steps. Our partner is looking for a Technical Support Engineer based in Netherlands.

This role offers an opportunity to support cutting-edge generative AI technology used by developers and businesses worldwide.
You will provide advanced technical support across APIs, platform functionality, integrations, and production issues.
Working closely with customers, engineering, and sales teams, you will help resolve complex problems and improve the overall product experience.
You will investigate issues through logs, error messages, authentication flows, and request/response data to identify root causes.
Beyond troubleshooting, you will contribute to product quality through bug reporting, feature validation, documentation, and actionable customer feedback.
The role is ideal for a technically curious, customer-focused problem solver who thrives in a fast-moving AI environment.
You will also help make the platform increasingly self-service by improving technical documentation and knowledge resources.

Accountabilities
  • Provide advanced technical support to customers, troubleshooting platform functionality, APIs, UI issues, errors, and integration challenges.
  • Support users across multiple products through channels such as email, chat, and Slack while maintaining a high standard of responsiveness and service.
  • Diagnose authentication and integration issues involving OAuth2, API keys, JWT, HTTP errors, malformed requests, rate limits, and API configuration problems.
  • Analyze logs, error messages, request and response payloads, and observability data to identify root causes and determine appropriate solutions.
  • Manage support cases within established SLA timeframes, maintain accurate case records, and escalate complex or unresolved issues to the appropriate teams.
  • Reproduce, document, and escalate bugs and edge cases in collaboration with engineering teams.
  • Share structured customer feedback with engineering and product stakeholders, highlighting recurring pain points, reliability concerns, performance bottlenecks, and opportunities for improvement.
  • Assist with testing and validating new features, product releases, and infrastructure changes before they reach production.
  • Create and maintain technical resources, including troubleshooting guides, FAQs, use-case documentation, how-to content, and documented solutions to recurring issues.
  • Improve developer-facing documentation and knowledge resources to make integrations easier and increasingly self-service.
  • Identify recurring support challenges and proactively recommend process improvements that enhance customer experience and operational efficiency.
Requirements
  • Demonstrated experience in technical support, technical operations, developer support, or a similar customer-facing engineering environment.
  • Strong analytical thinking and systematic troubleshooting skills across web platforms, APIs, cloud environments, and enterprise software.
  • Hands-on experience supporting and troubleshooting REST APIs and backend services, including authentication mechanisms such as OAuth2, JWT, and API keys.
  • Ability to investigate technical issues using monitoring, logging, and observability tools.
  • Familiarity with AI platforms, machine learning systems, generative AI, or data-intensive applications is highly valuable.
  • Strong written and verbal English communication skills, with the ability to explain complex technical concepts clearly and empathetically to both technical and non-technical users.
  • Customer-first mindset with patience, empathy, sound judgment, and a strong focus on helping users achieve successful outcomes.
  • Strong technical writing skills, with experience producing user guides, FAQs, troubleshooting documentation, and knowledge-base content.
  • Ability to prioritize multiple concurrent support cases, respond with urgency to critical issues, and remain composed in a fast-paced environment.
  • Comfortable working independently while collaborating effectively with engineering, sales, product, and other internal teams.
  • Self-motivated and proactive, with the ability to identify recurring problems and initiate improvements rather than simply resolving individual tickets.
  • Familiarity with collaboration and development tools such as Slack, Linear, Notion, and GitHub.
  • Strong understanding of API concepts, authentication flows, HTTP errors, and backend integration patterns.
Benefits
  • Competitive salary and equity package.
  • Fully remote work with the flexibility of working from anywhere.
  • Opportunity to work on challenging problems at the forefront of generative AI and AI infrastructure.
  • Significant learning and professional growth opportunities in a rapidly scaling technology environment.
  • Exposure to sophisticated AI platforms, APIs, production systems, and developer-focused technologies.
  • Regular team events and offsites designed to strengthen collaboration and team connections.
