Requirements
  • 7+ years of experience in enterprise security, cloud architecture, or technical pre-sales, with significant exposure to regulated industries in EMEA (financial services, insurance, healthcare)
  • Deep technical knowledge of enterprise security concepts: network security, identity and access management, encryption (at rest and in transit), API security, and audit/logging requirements
  • Deep working knowledge of GDPR (data residency, data retention and Zero Data Retention, international transfers, DP IAs) and strong familiarity with the EU AI Act as it applies to foundation models
  • Experience navigating compliance frameworks relevant to European financial services and insurance (DORA, NIS2, SOC 2, PCI-DSS, and national regulators' guidance on AI/ML such as FCA/PRA, BaFin, ACPR, FINMA)
  • A track record of leading complex, high-stakes engagements with CISOs, security teams, and compliance officers at large European enterprises
  • Strong understanding of cloud architecture and deployment models (AWS, Azure, GCP), including VPCs, private endpoints, hybrid connectivity, and the European sovereign cloud landscape

  • Partner with CISOs, security architects, compliance teams, and DPOs to understand their security requirements and design solutions that meet European regulatory standards (GDPR, EU AI Act, DORA, NIS2, SOC 2, PCI-DSS, and national regulators' guidance on AI/ML such as FCA/PRA, BaFin, ACPR, FINMA)
  • Lead technical deep-dives on network architecture, EU data residency, data retention and Zero Data Retention (ZDR) policies, cross-border data transfers, API security, authentication/authorization, audit logging, and integration patterns for regulated environments
  • Support enterprise security reviews, vendor assessments, and due diligence with detailed technical documentation and expert guidance
  • Guide customers through EU AI Act readiness, DORA, and NIS2, and position Anthropic within the European competitive landscape

Simplify's Take

What believers are saying

  • Anthropic raised $65 billion on May 28, 2026, valuing it at $965 billion.
  • Reuters on August 20, 2026 says over 100 customers shaped its data-policy redesign.
  • Claude's global watermark rollout strengthens EU compliance and enterprise trust after August 2, 2026.

What critics are saying

  • Reuters on August 20, 2026 says enterprise customers still face 30-day retention.
  • OpenAI's Private Safety Processing directly attacks Anthropic's privacy differentiation with no-retention monitoring.
  • A failed chip program or Samsung manufacturing misfire keeps Anthropic trapped on expensive third-party compute.

What makes Anthropic unique

  • Claude Code and enterprise API revenue anchor a developer-first, usage-based moat.
  • Anthropic built mandatory watermarking and retention controls faster than rivals after EU AI Act.
  • Its new silicon team targets co-designing chips with Claude to halve inference costs.

Anthropic poaches Google TPU founder to build custom AI chips and cut inference costs in half

Anthropic has hired Amir Salek, founder of Google's Tensor Processing Unit programme, for its compute team. Salek spent four years away from chip design after leaving Google in 2022 to invest in deep-tech startups at Cerberus Capital Management. This follows Anthropic's June hiring of Clive Chan, formerly the second engineer on OpenAI's custom chip programme. The AI company confirmed in August it is building an in-house silicon team to co-design chips with Claude models, aiming to halve inference costs. TechCrunch reported Anthropic has held early manufacturing discussions with Samsung. The moves come whilst Anthropic relies heavily on Google's TPUs, having agreed to purchase up to a million units in October.

Anthropic rolls out AI text watermarks globally to comply with EU law

Anthropic has introduced watermarks for text generated by its AI model Claude, following requirements under the European Union's Artificial Intelligence Act. The watermarks, which apply globally, use a method developed by Google that involves selecting specific words and fragments to create a statistically detectable pattern. The EU's AI Act, whose high-risk AI rules took effect this month, mandates transparency in AI-generated content. Companies violating the law face fines of up to 7% of global revenue. The watermarks are invisible to readers and don't affect text quality. They remain embedded when text is copied or edited, allowing potential identification of AI-generated content anywhere. The move is expected to increase tensions between the Trump administration and the EU over digital regulation. President Trump recently announced plans to review and potentially retaliate against what he called the EU's "discriminatory" digital practices.

Anthropic hires Google chip veteran to lead custom semiconductor push

Anthropic PBC has hired Amir Salek, a founder of Google's custom chip programme, as the AI lab prepares to develop its own semiconductors. Salek brings extensive experience from Alphabet's hardware efforts, where he played a key role in establishing the company's custom chip initiative. His appointment signals Anthropic's strategic shift towards hardware development. The move follows a broader industry trend of AI companies designing proprietary chips to optimise performance and reduce reliance on third-party suppliers. Custom semiconductors can offer significant advantages in power efficiency and computational capabilities for AI workloads. Anthropic joins other major AI labs in pursuing vertical integration through hardware development, a strategy that could provide greater control over its technology stack and long-term competitive positioning.

Anthropic lets enterprises store AI data on own infrastructure amid cost pressures

Anthropic will allow enterprise customers to store required data on their own cloud infrastructure, Reuters reported, citing an unnamed source. The AI company maintains its 30-day data retention requirement but now permits businesses to keep that data on their systems rather than Anthropic's. The policy applies to Anthropic's Fable and Mythos models and future frontier models. Anthropic introduced the 30-day retention requirement in June to protect against cyberattacks using its technology. The move follows mounting pressure on enterprise AI spending, with some companies switching to cheaper alternatives like DeepSeek. AI startup Lindy recently migrated from Anthropic's Claude models to DeepSeek, expecting to save millions of dollars within months. Anthropic filed a confidential IPO prospectus in June. Its annualised revenue run rate reached $47 billion in May, according to CNBC.

Medialister joins Anthropic's Claude Connectors Directory for AI-powered media placement planning

Medialister announced its MCP connector is now available in Anthropic's Claude Connectors Directory. The integration allows Claude users to research publications and identify editorial advertising opportunities through natural-language conversations within their existing AI workflow. Communications, SEO, content, and growth teams can use the connector to build media placement shortlists, compare outlets against campaign requirements, and turn briefs into research workflows inside Claude. Use cases include finding publications relevant to specific audiences, geographies, or industries, and planning product launches or PR campaigns. The connector is accessible through Claude's in-product browsing and search experience. Users can add it via Settings → Connectors → Browse Connectors. Whilst the connector handles discovery and planning, campaign booking remains within Medialister's platform. Medialister provides a platform for editorial advertising and media placements, helping brands and agencies discover publication opportunities and plan campaigns at scale.
