About Sent
Sent provides a cutting-edge infrastructure for transmitting A2P messages seamlessly across SMS, WhatsApp, and RCS through a single unified API. Our advanced routing model automates channel selection, optimizing for deliverability and cost-effectiveness, ensuring expansive global reach without the need for channel-specific integrations.
Backed by notable investors including Companyon Ventures, Bessemer Venture Partners, UIF, and CEAS Investments, we recently secured a $5.1M Seed round. Join us as we revolutionize the messaging landscape by building the ultimate infrastructure to replace traditional multi-channel messaging systems.
About the Role
As the Technical Solutions Manager at Sent, you will take charge of the post-sale relationship with our clientele—from their initial API call to handling full-scale production traffic. You will be the essential support for developers and their teams, ensuring that messaging functions smoothly, remains operational, and evolves over time.
This role is technical and customer-focused; your mission is not to sell but to guarantee customer success. This requires diving deep into API logs, scrutinizing webhook configurations, resolving delivery issues, and proactively identifying potential problems before they affect customers. You will oversee a complete portfolio: onboarding, ongoing health, expansion, and retention.
This position suits individuals with a few years of experience in a technical customer-facing role who aspire to take ownership of their function within an early-stage company rather than just following an existing framework.
Your Responsibilities
Onboarding & Integration Support
- Manage customer onboarding from start to finish, assisting engineering teams as they transition from sandbox to production.
- Examine customer integration code, identify challenges, and collaborate directly with developers to find solutions.
- Create and enhance onboarding playbooks for various use cases (transactional, marketing, authentication, multi-channel).
Technical Support & Troubleshooting
- Act as the primary technical contact for your accounts after the sale.
- Resolve delivery issues across channels, including carrier filtering, template rejections, routing failures, and webhook misconfigurations.
- Identify and escalate product bugs with clear reproduction steps and context for engineering.
- Delineate between customer misconfigurations and platform issues, managing both effectively.
Customer Health & Expansion
- Monitor customer health metrics and identify opportunities for expansion and increased engagement.
- Foster strong relationships with customers, ensuring they derive maximum value from our solutions.
