About the Role

This role supports one of our global SaaS partners in the shipping and logistics technology space. Their platform powers e-commerce businesses by providing APIs and integrations that connect merchants with carriers, generate shipping labels, and streamline logistics workflows.

This is a senior, hands-on technical role focused on resolving complex, high-impact customer issues related to API usage, integrations, and backend workflows. You’ll act as a subject-matter expert for API-based support cases, partner closely with Engineering and Product, and translate customer-reported issues into clear, actionable insights.

This role is ideal for someone who thrives on deep problem-solving, technical investigation, and customer advocacy without being on a formal engineering track.

What You’ll Do

• Own and resolve Tier 3 and escalated support cases, with emphasis on APIs, integrations, and shipping workflows
• Investigate API-related issues including authentication, webhooks, rate limits, label creation, carrier responses, and error handling
• Analyze logs, request and response payloads, and backend data to identify root causes
• Use SQL to query internal databases, validate data integrity, and trace transactions
• Read and interpret code snippets in Python, JavaScript, Ruby, or PHP to understand customer implementations and identify likely issues
• Reproduce customer issues in sandbox or test environments when needed
• Partner with Engineering to escalate bugs, provide clear reproduction steps, and validate fixes
• Collaborate with Product and Solutions teams to identify API usability gaps and improve developer experience
• Contribute to internal documentation, runbooks, and troubleshooting guides
• Share investigation patterns and techniques with L1 and L2 teams to strengthen enablement
• Identify recurring issues and recommend improvements to processes, tooling, or product design

Requirements:
What We’re Looking For

• 3 to 5+ years’ experience in Technical Support, Customer Support Engineering, or a similar technical customer-facing role
• Strong working knowledge of REST APIs, including authentication, webhooks, and JSON payloads
• Hands-on experience writing and executing SQL queries for investigation and reporting
• Ability to read and reason about code in at least one common language such as Python, JavaScript, Ruby, or PHP
• Comfort working with logs, API testing tools such as Postman or curl, and debugging distributed systems
• Proven ability to explain complex technical concepts clearly to non-technical and semi-technical customers
• Strong written communication skills for customer updates, internal notes, and escalation summaries
• Calm, methodical approach to high-stakes or time-sensitive customer issues
• Experience supporting developer-facing products or APIs in a SaaS environment
• High attention to detail and a bias toward root-cause analysis over quick fixes

Nice to Have

• Experience supporting shipping, logistics, e-commerce, or marketplace platforms
• Familiarity with tools such as Zendesk, Jira, Datadog, or similar support and observability platforms
• Prior experience acting as an informal technical lead or escalation point within a support team

Benefits:
• Competitive full-time compensation

• Collaborative office space and culture
• Medical allowance
• Exposure to a fast-growing global client in the SaaS/tech space
• Birthday leave + professional development budget
• Join a supportive, resourceful, and global team that values action, clarity, and empathy

This is a full-time position working from 3:00 pm to 12:00 am SAST. This is an in-office role, based at our Wembley Square, Cape Town location. Reliable commuting to and from the office is required.
