Internal Communications Manager, Tech

Anthropic’s mission is to create reliable, interpretable, and steerable AI systems. We want AI to be safe and beneficial for our users and for society as a whole. Our team is a quickly growing group of committed researchers, engineers, policy experts, and business leaders working together to build beneficial AI systems.

Anthropic is seeking an Internal Communications Manager to serve as a dedicated communications partner to our Core Tech organization (the teams building and securing the systems behind Claude, from engineering and infrastructure to security). Depending on your background and where the need is greatest, your portfolio might center on security, on engineering more broadly, or span both - we'll shape that together during the hiring process.

Internal communications at Anthropic is not a support function that plans meetings and sends newsletters. The best people in this role operate like advisors who embed themselves deeply in the orgs they support, earn a seat at the leadership table, write on behalf of executives, and see around corners, anticipating what the organization will need to hear before anyone asks for it. There are traditional elements to the role too, like all-hands planning and org change announcements, and you'll run those with operational excellence. But the heart of the job is more creative and will require you to find ways to connect the rest of the company to some of the most consequential and least visible work at Anthropic, and making the line between that work and our mission clear and strong.

The work of Core Tech is deeply technical and the company depends on it (like architecting new products for Claude to reach users, model inference, capacity planning, building reliable systems, and the security that protects all of it) but most employees rarely see this work directly…unless something goes wrong. Your job is to change that by understanding this work, and the people doing it, well enough to tell its story credibly, and to help its leaders communicate with clarity and candor as the company scales.

• Own the internal communications strategy for your portfolio within Core Tech, becoming an expert in the team's work and a trusted member of its leadership team

• Serve as a hands-on advisor to executives - help them think through what to say and when, draft communications in their voice, and give them honest counsel, especially in moments when that’s challenging or uncomfortable.

• Translate deeply technical work into narratives that land with employees across every function, without losing the substance

• Get creative about how you connect people to the work - don't default to creating a slide deck when a demo or something no one has tried yet would land better

• Anticipate communications needs before they arrive (e.g. launches, incidents, organizational change, moments of external attention) and have a plan ready for how we’ll bring employees along

• Design and implement strategies to boost signal and reduce noise, so employees know what's important and what it means for them

• Plan and execute internal fora like all-hands and AMAs with operational excellence

• Exercise sound judgment with sensitive material, especially where security work requires care about what is shared, with whom, and when

• Partner closely with the broader internal communications team to ensure updates are accurately and consistently cascaded across existing channels and live forums

You may be a good fit if you

• Have 8–12 years of experience in communications or an adjacent craft where you learned to make complex, high-stakes material clear under pressure (e.g journalism, speechwriting, chief of staff work, strategy and operations)

• Are an exceptional writer
