About Subquadratic

Subquadratic is an AI infrastructure and research company building a new class of LLMs on a proprietary post-transformer architecture. While the major labs focus on incremental transformer improvements, we're pushing foundational change at the model architecture level - enabling large-context, multimodal inference that scales efficiently where transformers can't.

About the Role

SubQ is building a next-generation LLM platform designed for efficient, long-context AI applications. We're looking for a Technical Copywriter who can take genuinely differentiated technology and make engineers understand why it matters - fast.

This isn't a documentation role. It's not a thought leadership role. It's the person who writes the launch blog post that makes an AI engineer stop scrolling, the benchmark deep-dive that gets cited on Hacker News, and the API guide that developers share in Slack because it's actually useful.

You'll own the technical content function from scratch - working directly with engineering, product, and GTM to produce content that drives developer adoption and earns credibility with a skeptical technical audience.

What You'll Own

Developer-facing technical content

• Launch blog posts and technical announcements written for engineers, not marketing audiences
• API quickstarts, integration guides, and tutorials that end with the developer having done something real
• SDK and API reference documentation that is accurate, complete, and fast to navigate

Benchmark and credibility content

• Launch benchmark reports with full methodology - structured to be cited by press and AI answer engines
• Technical comparison content written with absolute metrics, not relative claims
• Ongoing benchmark and evaluation content that keeps SubQ visible as the competitive landscape shifts

SEO, AEO, and GEO content

• Evergreen technical content optimized for search and AI answer engine citation
• Content strategy that treats engineers as the primary reader and rankings as a byproduct
• Structured content that surfaces correctly in LLM-generated answers - not just Google

What We're Looking For

• You've written technical content for a developer-first company. Your portfolio has pieces engineers have actually shared or cited.
• You understand AI infrastructure and LLMs at an engineering level. You can write about inference tradeoffs, context windows, and API design without being briefed on what those things mean.
• You write with conviction. Specific claims, sourced numbers, no hedging. Absolute metrics land harder than relative ones.
• You know the difference between writing for search, writing for AI citation, and writing for technical communities - and you've done all three.
• You're comfortable working directly with engineers. Technical accuracy isn't someone else's problem - it's yours.
• You have strong opinions about what good developer content looks like. Stripe's docs and the Cloudflare blog are useful reference points for the standard we're aiming for.
• You have experience writing benchmark methodology documentation or ML evaluation content
• You've built with LLM APIs in production - not just written about them

Compensation & Benefits

• Competitive base salary
• Performance-based bonus aligned with research and model milestones
• Equity participation
• Comprehensive health, dental, and vision coverage
• Flexible paid time off
