Technical Writer (1yr Contract)

직무 소개

The Company Sendbird is on a mission to build the AI workforce of tomorrow. For over a decade, we built the infrastructure behind conversations—chat, voice, video, messaging APIs—and became the #1 CPaaS platform for in-app communications. 4,000+ brands trust us. 7 billion messages flow through our platform every month. 300 million monthly active users. We powered conversations for DoorDash, Match Group, Noom, Yahoo Sports, Rakuten, and thousands of others. We were good at what we did. Really good. We also saw it early: AI would fundamentally reshape how businesses talk to customers. The infrastructure we'd spent a decade building would become commoditized. The value would move up the stack—into intelligence, into experience, into outcomes. We had a choice: protect what we built, or reinvent ourselves. We chose reinvention. In December 2024, we made the full strategic pivot to AI-first customer experience. By February 2025, we'd launched our AI agent for enterprise CX—built on a decade of conversation data, now with intelligence on top. And in November 2025, we rebranded to delight.ai. The name says it all. AI's real promise isn't efficiency or cost savings. It's giving customers back something they lost—the feeling of being truly understood and cared for. Not satisfied. Delighted The Product Delight.ai is the AI concierge for customer experience. Most AI agents forget you the moment the conversation ends. Ours doesn't. Delight.ai builds memory over time, learns preferences, and connects context across every channel without losing the thread. We're building AI that makes customers feel understood, seen, and remembered. The Role The Technical Writing team at Sendbird empowers developers to build successful businesses on our platform by delivering high-quality content — from documentation and user guides to tutorials, UI text, and beyond. As a Technical/UX Writer, you'll be at the center of the developer experience, transforming complex technical concepts into content that is clear, concise, and actionable. You might be this person if * You quickly spot friction in the user experience — whether it's a confusing UI label, unclear documentation, or a workflow that loses developers halfway through — and you can articulate exactly what's wrong and why. * You're a critical thinker who questions the obvious and finds a better path when the conventional one doesn't work. * You're genuinely curious about AI — not just as a trend, but as a tool you actively use to work faster and smarter. Sendbird encourages all members to tap into the most advanced tools available. * You thrive in cross-functional work. You'll collaborate closely with product managers, engineers, and UX designers to create content that meets real customer needs. * You take ownership. You don't wait to be told what needs fixing — you spot it, flag it, and drive it forward. * You're not afraid to ask questions. When you need context, resources, or a second opinion, you seek them out — proactively and without hesitation. What you'll actually do * Create content: Develop and maintain high-quality documentation, user guides, and UI text strings for Sendbird's products, ensuring clarity and accuracy. * Write UX copy: Craft button labels, error messages, onboarding flows, and tooltips that guide users with minimal friction. * Improve content: Build an effective feedback loop and integrate customer insights into our content. * Work with AI: Use AI tools actively in your writing workflow — to draft, restructure, automate, and iterate — while applying your own judgment to every output. * Stay current: Research competitor products, B2B trends, and developer communities to keep our content competitive and relevant. You need to have * Experience: 0–2 years in technical writing, UX writing, content design, or a related field. * Content writing sense: You notice when content does not deliver its message effectively — and you can explain why. This is foundational to how we work. * AI proficiency: You've used AI tools in real writing or content work. You know how to direct them with purpose, and you treat their output as a first draft. * Writing and communication: Fluent in English and Korean, both written and verbal. * Collaborative tools: Familiar with Git, GitBook, Confluence, Jira, Figma, or similar tools. * Education: Bachelor's degree or equivalent experience. Added value * Background in Computer Science, Technical Writing, or a related field. * Experience with AI or SaaS product development. * Familiarity with API, SDK, or any programming languages such as Swift, Kotlin, or JavaScript. Our KR benefits include (but are not limited to) * Be Your Best Self: 3.9 million won (prorated by start date) for expenses ranging from professional development classes and training, to personality assessments, to gym memberships, to books, to fitness classes, to mental health services, to massages * Annual cash-equivalent special welfare points of 200,000 KRW for Seollal and Chuseok holidays each * Learn a Language benefit - up to 3.6 million won per year towards language lessons * Weekly team lunch * Monthly team building cost * Partial support for commuting costs * Free parking at the Seolleung office * Group insurance support that covers employees, spouses, and children * Medical checkup support, including MRI and genetic testing - for the employee and one family member * Seven additional paid holidays in addition to annual leave (Boost leave, Birthday leave, etc.) * Support for the latest work devices, such as MacBook Pro (special support options for each job position) * Unlimited snack bar filled with snacks, beverages, and instant noodles every day * 12-week paid parental leave support (available for both mothers and fathers) * Other support programs for congratulations and condolences Flexible Work Policy We offer a flexible work schedule at Sendbird. We also value collaboration and relationship building. With those values in mind, we require all employees to gather with their team in the office three days per week as a minimum. Some of our roles require a more frequent in-office schedule. Please work with your manager to understand the office time requirements for your position. What diversity and inclusion mean to us There is no such thing as a perfect candidate and the best employees come from a wide range of backgrounds, experiences, and skill sets. Sendbird is a place where everyone can learn and grow. We respect, promote, and encourage diversity for equal employment opportunities and encourage you to apply if this role excites you. Why Sendbird We spent a decade building the conversation infrastructure that the world runs on. Now we're putting intelligence on top of it. You won't be joining a company still figuring out its AI strategy. You'll be joining one that has already made the bet, shipped the product, and is moving fast to lead the category. If you want to build something that matters, with a team that knows how, this is it.
