An Introduction to Primer
Primer is the unified infrastructure for global payments. We give finance and payments teams the visibility and control to reduce complexity, improve performance, and capture more revenue - all from a single platform.
Backed by Sofina, Peak XV Partners, ICONIQ, Tencent, Accel, and Balderton, we're building the payments layer the world's best companies rely on.

🔍 What will you be doing?Payment performance & risk mitigation
Proactively monitor merchant integration and payment performance (authorisation rates, network tokenisation coverage, routing configuration) and flag risk before it becomes a problem.
Recommend and drive routing/NT/config changes, making the economic case (auth rate, cost) for why they matter.
Integration debugging
Root-cause complex technical issues hands-on, failures, SDK conflicts, webhook gaps, using logs, traces and API behaviour.
Loop in Primer engineering only when genuinely needed, rather than as a first resort.
Technical escalation ownership
You will act as an escalated contact during incidents that affect key merchants and require support from someone who has context on their particular payment stack. This sort of activity will be done in close contact with Support.
During and after incidents, you will be in touch with key merchants to deliver RCA’s, walk-through any impacts and offer recommendations to prevent future exposure.
Enablement & solution design
Lead technical deep-dives and solution design sessions when a merchant adopts a new PSP connector, payment method, or unreleased Primer product as a design partner.
Manage the expectation gap through rollout and feed structured, usable feedback back to Product and Engineering.
Proactive technical reviews
Run recurring technical integration reviews (e.g. quarterly) with each merchant's engineering/payments stakeholders, covering integration health, optimisation opportunities, and risk, independently of any commercial QBR run in-partnership with the AM.
Regulatory & compliance navigation
Translate changes in card scheme rules or regional regulation (e.g. BNPL rules, PCI requirements) into a concrete technical plan for each affected merchant.
Deep, hands-on technical ability: comfortable reading API logs and traces, debugging integration issues directly, and writing basic scripts/SQL to investigate an issue — a real technical peer to a merchant's engineers, not a relationship manager with technical vocabulary.
Experience in a technical, merchant/customer-facing role: Technical Account Manager, Solutions Engineer, Support Engineer, Customer Success Manager (technical focused), Implementation Specialist, in payments, fintech, or e-commerce.
Strong understanding of APIs, webhooks, and SDKs: The ability to explain technical flows clearly to both engineers and non-technical stakeholders.
A proactive operating style: Comfortable identifying and surfacing risk before being asked, not just responding to tickets.
Confidence and credibility presenting technical material: Comfortable presenting to senior technical stakeholders (VP Engineering, Head of Payments) at enterprise merchants.
Comfortable owning ambiguity: Coordinating across Primer's engineering, product, and support teams without heavy oversight.
Direct experience with payments infrastructure: network tokenisation, PSP connectors/routing, or card scheme mechanics.
Design-partner support experience: exposure to beta or early-access product rollouts across key merchants.
Not a renewals or commercial negotiation owner, that's the Account Manager.
Not a support/ticket-routing role, the bar is proactive technical ownership, not reactive Q&A.
