DESCRIPTION

Sinch Build is becoming the programmable foundation for how enterprises communicate with customers—across messaging, voice, numbers, and AI-driven agents.

We’re investing heavily in APIs, MCP servers, AI integrations, and a unified developer experience. What we don’t yet have is a single owner whose job is to represent developers inside Sinch—and Sinch to developers.

This is our first Developer Relations hire for Sinch Build. You’ll help define what DevRel means at Sinch from the ground up.

What you’ll work on

You’ll sit at the intersection of product, engineering, and external developers, with real influence over platform direction.

Developer Experience & Advocacy

• Be the voice of developers using Sinch Build APIs (messaging, voice, numbers, conversations, AI integrations).
• Turn developer pain into clear product and platform priorities.
• Partner closely with Product and Engineering to improve API usability, auth flows, SDKs, and docs.

Technical Content & Enablement

• Create high-quality technical content: guides, tutorials, sample apps, reference implementations.
• Help define how Sinch APIs are exposed to AI agents, LLM platforms, and external builders.
• Shape our developer documentation strategy together with the docs team.

Community & Ecosystem

• Engage directly with developers building on Sinch (startups, integrators, AI builders).
• Represent Sinch Build in developer communities, events, hackathons, and online forums.
• Help build relationships with AI platforms, agent frameworks, and tooling ecosystems.

Product Feedback Loop

• Run structured feedback loops: early access programs, beta users, prototypes.
• Validate new platform capabilities with real developers before launch.
• Help ensure Sinch Build is competitive in our market.

What makes this role special

• Founding DevRel role – you define the playbook.
• Deep technical surface: APIs, voice, messaging, numbers, AI agents, MCP servers.
• Direct access to platform leadership and real influence on roadmap.
• Global scale: developers building real customer communication at massive volume.
• A platform in transformation—from CPaaS to AI-native communication infrastructure.

REQUIREMENTS

You don’t need to check every box—but you should be excited by most of them.

You likely have experience with:

• Developer-facing platforms, APIs, or SDKs (CPaaS, SaaS, infra, AI tools).
• Writing or building things developers actually use.
• Talking to engineers as an engineer—not as marketing.
• Translating technical feedback into product improvements.

You might come from:

• A DevRel, Developer Advocate, or Developer Experience role.
• A senior engineer or solutions architect role with strong communication skills.
• A startup or platform company serving developers.

Bonus points if you’ve worked with:

• Messaging, voice, WebRTC, SIP, or CPaaS.
• LLMs, AI agents, or agent frameworks.
• Open-source communities or API ecosystems.

Our corporate language is English, please submit your application in English.

At Sinch, we value learning, embrace change, and offer opportunities for personal and professional growth. Unfortunately, we are not supporting relocation at this time.

Applicants must:

• Hold Swedish or EU/EEA citizenship.
• Have a valid Swedish work permit.
