About the role

We’re looking for a reliable, organised, and experienced Senior Technical Support Specialist who thrives on solving problems and helping merchants succeed. You’ll play a key role in supporting our clients with technical questions, troubleshooting platform issues, and guiding them to get the most out of Swap. This role sits at the crossroads of support, product, and ops: part detective, part educator, part technical translator. You’ll handle urgent escalations, collaborate closely with engineering and product, and also build longer‑term improvements to make support faster and smarter. You’ll combine a technical mindset with a customer‑first approach, and you’ll have the opportunity to make a real impact in a fast‑paced scale‑up environment.

What You Will Do

• Investigate complex technical issues escalated from our CX team.
• Review API logs and internal monitoring systems.
• Act as the Tier 2/3 escalation point for advanced cases (API errors, webhook failures, customs/documentation issues, Stripe disputes).
• Own high‑impact workflows, including:

• Stripe Dispute Evidence submissions.
• Customs documentation (HS codes, COO, commercial invoices).
• Carrier claims (lost/damaged parcels).
• Label regeneration & advanced shipping rules.

Requirements

• 4+ years in Technical Customer Support, ideally in SaaS, e‑commerce, or logistics.
• Strong working knowledge of:

• APIs & webhooks (authentication, error codes, debugging).
• E‑commerce platforms (Shopify, BigCommerce, WooCommerce).
• Payments & disputes (Stripe or similar).
• Shipping & logistics (carriers, customs docs, duties/taxes).

Nice to Have

• Experience in a startup/scale‑up environment.
• Familiarity with support tools like Intercom, Linear, or Jira.
• Knowledge of customs regulations, HS codes, or international trade.
• Experience with dispute/chargeback management.
• Ability to scope and recommend technical solutions, including integrations or customisations.

What Success Looks Like

• Complex merchant issues are resolved quickly and thoroughly.
• Support efficiency improves through better processes, documentation, and enablement.
• Junior team members become more confident handling advanced cases.
• Swap’s merchants report higher trust and satisfaction after escalations.
• Insights from support drive measurable product improvements.

Why Join Swap

• Be part of a fast‑growing scale‑up tackling the toughest challenges in commerce.
• Own high‑impact projects and directly shape the future of Technical Support.
• Work with smart, motivated teammates across Support, Product, and Engineering.
• Hybrid Flexibility: 3 days in our TCR office, 2 days remote.

Benefits

• Competitive base salary.
• Stock options in a high‑growth startup.
• Competitive PTO with public holidays additional.
• Private Health.
• Pension.
• Wellness benefits.
• Breakfast Mondays.
