Technical Account Manager

About The Company

Rain makes the next generation of payments possible across the globe. We’re a lean and mighty team of passionate builders and veteran founders. Our infrastructure makes stablecoins usable in the real-world by powering card transactions, cross-border payments, B2B purchases, remittances, and more. We partner with fintechs, neobanks, and institutions to help them launch solutions that are global, inclusive, and efficient. You will have the opportunity to deliver massive impact at a hypergrowth company that is funded by some of the top investors in fintech, crypto, and SaaS, including Sapphire Ventures, Norwest, Galaxy Ventures, Lightspeed, Khosla, and several more. If you’re curious, bold, and excited to help shape a borderless financial future, we’d love to talk.

Our Ethos

We believe in an open and flat structure. You will be able to grow into the role that most aligns with your goals. Our team members at all levels have the freedom to explore ideas and impact the roadmap and vision of our company.

About The Role

As a Technical Account Manager, you'll be Rain's embedded technical expert within the post-sales team. You will be the dedicated technical resource for strategic partners and the force multiplier that raises the bar for how our entire partner-facing organization operates. You'll work directly alongside Senior Implementation Managers and Account Managers, serving as the technical authority across complex integrations, technical platform and API questions, and new capability rollouts. At the same time, you'll turn hands-on partner experience into durable assets - playbooks, integration guides, and documentation - that empower our IMs and AMs to move faster and more efficiently across all partners. The right person is as comfortable whiteboarding with a partner's engineering team as they are writing a guide that helps a non-technical AM navigate a platform change with their partners.

What You’ll Do

• Serve as the dedicated technical point of contact for strategic partners.
• Build and maintain implementation playbooks, integration guides, and technical runbooks for new product and feature launches.
• Lead technical working sessions with partner engineering teams, review integration approaches, and ensure partners are building on Rain's platform for long-term success.
• Diagnose issues spanning APIs, webhooks, authorization flows, and card network configurations, owning resolution communications and coordinating with engineering.
• Surface patterns from partner interactions as structured feedback to Product and Engineering, and project manage delivery with cross-functional teams.
• Conduct regular reviews with enterprise partners covering integration health, open issues, upcoming platform changes, and opportunities to expand platform usage.

What we're looking for

• 3–5+ years in a client-facing technical role (e.g., Technical Account Management, Solutions Engineering, Implementation Engineering, or similar).
• Bachelor's degree in Engineering, Computer Science, or related field.
• Expert-level comfort with APIs; ability to read documentation, test endpoints, and debug integration failures hands-on.
• Hands-on experience with JavaScript, SQL, and/or other programming languages.
• Experience managing complex, multi-stakeholder engagements across competing timelines.
• Ability to move fluidly between a partner's engineering standup and an executive business review.
• A builder's mindset: document, systematize, and improve processes.

Nice to have, but not mandatory

• Background in payments, card issuing, or fintech infrastructure.
• Familiarity with card network concepts (authorization, settlement, disputes, BINs) or stablecoin/digital asset platforms.

Things that enable a fulfilling, healthy and happy experience at Rain:

• Unlimited time off (minimum 10 days required).
• Flexible working environment (home or office).
• Comprehensive health, dental, and vision plans for US Rainmakers.
• 401(k) with a 4% company match.
• Equity option plan for all Rainmakers.
• Rain Cards for product testing and eligible health/wellness spending.
• Team summits and offsites (domestic and international).
