About the job

Requirements
  • Have at least 8 years of experience writing for developers or technical audiences, with a portfolio showing both technical and brand work.
  • Have shipped work that developers shared, in-house at a developer tools or infrastructure company or at an agency serving those clients.
  • Have a strong, specific point of view on how brands should talk to developers and be able to articulate it with examples.
  • Be able to read changelogs or documentation and assess why developers would or would not trust them.
  • Be skilled at adapting expert material into accurate, sharp short-form copy and launch narratives.
  • Work fluidly across technical content and brand writing.
  • Already use Claude or other AI models in personal writing practice and be able to discuss concretely how.
  • Enjoy embedding with technical teams and treating engineers and developer relations as creative partners, not just reviewers.
  • Be comfortable co-owning standards with other teams and knowing where role boundaries lie.
  • Be excited about Anthropic's mission to develop safe and beneficial AI.
  • Have a bachelor's degree or equivalent combination of education, training, and experience; relevant field study may be demonstrated through coursework, training, or professional experience.
Responsibilities
  • Own the developer-facing expression of brand campaigns, translating brand-level ideas into writing for launches, social media, and paid campaigns.
  • Build the developer voice and tone guide with Communications and Developer Relations, then create templates and examples for developer work.
  • Own brand-led developer assets between technical content and marketing, including event and campaign materials and writing for enterprise contexts.
  • Partner daily with Developer Relations as an embedded extension of the team, complementing rather than duplicating its technical content.
  • Develop launch narratives and short-form copy that adapts expert technical material into accurate writing developers trust.
  • Lead copy for the developer creative pod, working alongside brand design and program management to deliver integrated work.
  • Partner with Claude Code leadership and developer marketing leadership on strategic initiatives shaping how the company communicates with developers.
  • Present work and explain voice and craft decisions to stakeholders across Brand, Developer Relations, Communications, and marketing.
  • Manage feedback from technical reviewers and Communications to ensure published work is accurate and approved for external communication.
  • Track how developer-facing work performs and use findings to improve the voice, templates, and work.
Desired Qualifications
  • Experience working directly alongside a Developer Relations or engineering team rather than working from a brief.
  • Experience building or contributing to a voice and tone guide, style system, or writing templates that others successfully used.
  • Experience writing developer launches at a fast-moving product company where accuracy and speed both mattered.
  • Familiarity with the AI developer ecosystem, including coding tools, APIs, and how developers evaluate them.
  • Experience writing developer-credible work that also performs in enterprise or executive contexts.
  • A personal writing practice, newsletter, or public work demonstrating voice and judgment.
  • Experience working within brand campaign systems and adapting them for a skeptical or specialized audience.

FTX's $500M Anthropic stake now worth up to $77B — but creditors sold for $1.3B

FTX's bankruptcy estate sold its 8% stake in Anthropic for $1.3 billion in 2024, a deal that looked profitable at the time. The AI company has since raised funds at a $965 billion valuation, meaning the stake FTX sold would now be worth between $60 billion and $77 billion on paper. The biggest buyer was ATIC Third International Investment, linked to Abu Dhabi's Mubadala fund, which paid nearly $500 million. Jane Street, where FTX founder Sam Bankman-Fried previously worked, bought $100 million worth. Other buyers included Fidelity, Ford Foundation, and HOF Capital. FTX creditors have recovered 103% to 120% of their claims, totalling roughly $10 billion across five payment rounds. However, claims were valued at November 2022 prices, when bitcoin traded around $16,000, meaning customers won't benefit from subsequent crypto appreciation or Anthropic's massive valuation increase.

Broadcom to lend Anthropic up to $42B to lease chips ahead of IPO

Broadcom has agreed to lend Anthropic up to $42 billion to finance infrastructure spending, according to the AI company's IPO filing. The convertible debt could fund roughly a third of Anthropic's $125.2 billion commitment for a five-year lease of tensor processing unit computing capacity. Anthropic is expected to become Broadcom's largest customer in its chip design business next year. The arrangement mirrors strategies used by Nvidia, which has leveraged its balance sheet to boost chip sales. The filing disclosed potential conflicts of interest, as Broadcom's dual role as hardware supplier and financing partner could affect Anthropic's access to computing power. Broadcom projects AI semiconductor revenue of approximately $115 billion in fiscal 2027 and $230 billion in fiscal 2028. The financing arrangement allows Broadcom to designate a financing partner, and the debt could convert into Anthropic shares.

Akamai lands $11.6B AI deal with Anthropic, shares jump 20%

Akamai Technologies announced an $11.6 billion, seven-year agreement with AI company Anthropic, which will use Akamai Cloud's infrastructure to support its CPU workloads. The deal includes provisions to expand by another $9 billion, potentially reaching $20 billion. Akamai also issued warrants to Anthropic that could represent roughly 5% of its outstanding shares. The Massachusetts-based cloud computing and cybersecurity firm had already secured $2.8 billion in multi-year cloud infrastructure commitments this year. Shares jumped over 20% following the announcement and are up 45% over the past year. The agreement will require $5.5 billion in new capital expenditures, with $1.7 billion realised in the fourth quarter. Analysts see significant upside, with a mean price target representing 44% potential gains from current levels.

Bill Ackman praises Anthropic but won't invest due to $42B losses and uncertain AI model advantage

Billionaire investor Bill Ackman praised AI startup Anthropic as "perhaps the greatest business story I've ever seen" but said his hedge fund Pershing Square likely won't invest in the company. Speaking to Bloomberg TV on Wednesday, Ackman lauded Anthropic's revenue growth and Claude product. However, he explained his fund prefers predictable, capital-efficient businesses like Microsoft, Visa, and Mastercard rather than fast-growing companies consuming substantial capital. He also questioned whether frontier AI models can maintain their advantage against lower-cost alternatives. Anthropic reportedly achieved nearly $4.6 billion in 2025 revenue, up 12-fold, but net losses reached $42 billion. The company is targeting a $2 trillion valuation in its planned IPO later this year. Pershing Square currently holds shares in Meta, Amazon, and Microsoft.

OpenAI launches marketplace letting customers use spend credits with 32 partners including open models

OpenAI has launched a marketplace allowing customers to retire spend commitments through 32 partners, mirroring AWS Marketplace's model. The move signals OpenAI's strategy to win through merit rather than coercion. By including Baseten, which provides access to open models, OpenAI demonstrates willingness to embrace competing models. This contrasts with Anthropic's approach, which blocks Claude Pro users from integrating with certain tools. The marketplace features caveats: only a fixed percentage of spend applies up to a cap, eligibility varies by customer and product, and billing occurs directly through partners. There's no self-service option at launch. The development positions OpenAI to benefit from customer decisions beyond model selection, potentially making its contract central to software purchasing decisions. This shift suggests AI labs are becoming the new cloud providers, whilst traditional cloud providers risk becoming less relevant to technology adoption decisions.
