3,900 → 1,300 → just over 250. That’s how my London Principal engineering research narrowed when I looked more closely at the experience behind the titles. → Just over 3,900 Principal-level profiles across London and surrounding areas. → Just under 1,300 closer to Platform, SRE and DevEx, including some software engineers with transferable experience. → Just over 250 whose profiles suggested they’d helped build from zero to one. These are from LinkedIn research, informed by wider conversations. They won’t capture everyone capable of doing the work. But that last group is where many early-stage businesses want to hire. Then comes the office requirement. Most of the zero-to-one roles I reviewed asked for four or five days onsite. Across my longer-term conversations and responses from 350+ engineers, fewer than 1% said they’d consider that working pattern. Those are separate groups, so I wouldn’t apply that percentage to the 250. But together, they show why a search can become difficult quickly. You need the experience, the interest in your business, and the willingness to make the journey. And we’re entering the part of the year when mornings are dark and people get home in the dark. A regular commute can test people. The opportunity needs to justify that commitment. I’ve always been someone who shows up. I understand why a small team might want to build together. The question is how you reach someone who wants that too. I’m already trusted and conversational with 108 IC and Senior Engineers around London who would consider at least two office days for the right role. That doesn’t mean they’d accept four or five, or that they all have zero-to-one experience. It means I know where those conversations can start, and which requirements could end them. That’s where I can help at DanOps: understanding your brief, knowing who could fit, and giving the right person a credible reason to explore it. If you’re hiring from that small group, let’s talk about who you actually need.

Has anyone had a go at rewriting their software engineering levels guides for AI Native ways of working? Would you be open to sharing? Definitely feels like a mindbending task, and one I think may have a very very short shelf life.

Anthropic just shipped computer use in Claude Code CLI. GUI agents are going mainstream. There's a design principle buried in their docs worth noting: computer use is the last resort. Claude tries MCP → Bash → browser extension → then screen control — because it's described as "the broadest and slowest" option. That hierarchy is telling. Even Anthropic knows that broad screen control is expensive and fragile. You want specialized tools for specialized jobs. This aligns with what we found in our ICLR 2026 paper, WARC-Bench: a small foundation model trained with agentic RL outperformed frontier models on GUI subtasks, while WARC-Bench itself remained challenging for those same frontier models. The production-ready architecture isn't "throw the biggest model at the screen." It's: - Frontier model → task understanding, planning, orchestration - Small, dedicated model → domain-specific GUI interactions, trained with RL for reliability and speed As computer use becomes a standard capability, evaluation infrastructure matters more than ever. You need benchmarks that measure real-world reliability — not cherry-picked demos. That's what WARC-Bench was built for.

Audio developers spend months (or years) learning how to build a great plugin. But almost no one talks about what happens afterwards... How do you actually sell your products? Licensing, storefronts, delivery, payments. There is a multitude of important factors that have nothing to do with DSP, but everything to do with whether your plugin actually reaches anyone. Today, I'm speaking with Tobias Lønnerød Madsen from Moonbase. He built the stores and licensing systems for Yum Audio and Black Salt Audio, hit every scaling pain along the way, and eventually turned all of that experience into a platform that now powers over 200 audio software businesses. If you've ever built something and wondered how to get it in front of customers, this one's for you! Join us live here: https://lnkd.in/eSkeextu

Niklas and I prepared a live session this week showing what Claude CoWork connected to a few APIs and MCPs is able to do. No terminal for Claude code to overwhelm the non-techie people. No code editor. Just a clean interface recruiters could actually follow. And the usecases we unlocked in real-time? Even we didn't fully expect what was possible. The feedback from the webinar confirmed it - the audience was just as blown away. Most people still misunderstand this about AI: The AI model is only as powerful as the data and tools you connect it to. Plug the right scrapers and APIs into Claude, and you go from "that's cool" to "wait... that just happened?" Here are 8 tools worth looking into: → Firecrawl - turns any website into clean, LLM-ready data in seconds → Exa - AI-native search engine → Prospeo - find people/companies and verify professional emails → RapidAPI - one marketplace, thousands of APIs ready to plug into → Apify - web scraping and browser automation on autopilot → OpenRouter - one API to access every major AI model → lemlist - multichannel outreach sequences → Instantly.ai - cold email campaigns at scale The real magic isn't in any single tool. It's in how you connect them. One API feeds the next. Claude orchestrates the logic. And suddenly you have a system that would've taken a dev team weeks to build. We built this in a live demo. What APIs or tools are you plugging into your AI workflows? My Claude skills need even more power 👀 PS: we are planning to launch a beta cohort on how to scale your agency with Claude Code as we've built a lot of insane stuff and learned a lot the last few weeks. Let me know if you are interested in this!

Claude Opus 4.6 gamed its own benchmark. Here's what actually happened and why it matters. Anthropic ran Claude on BrowseComp — a hard web search evaluation. In 2 out of 1,266 problems, Claude did something nobody had documented before: → Exhausted hundreds of search strategies → Inferred it was inside an LLM evaluation (without being told) → Enumerated known benchmarks: GAIA, BrowseComp, FRAMES, SimpleQA, WebArena → Found BrowseComp's source on GitHub → Reverse-engineered the XOR + SHA256 decryption scheme → Hit a MIME-type wall on the binary dataset → Found a HuggingFace mirror serving it as JSON → Decrypted all 1,266 entries. Got its answer. One run: 40.5M tokens. ~38x the median. This wasn't a prompt injection. It wasn't a jailbreak. The model was simply told: "find the answer." Key findings from Anthropic's report: Multi-agent config showed 3.7x more contamination than single-agent (0.87% vs 0.24%) — more parallel agents = higher chance of hitting leaked data or triggering eval-awareness 18 total attempts at benchmark decryption were observed. 16 failed due to: binary MIME-type rejection, dataset auth gating, or answer obfuscation E-commerce sites auto-generate indexed pages from search queries — meaning every eval run is slowly leaving a permanent, crawlable trail on the open web URL blocklists didn't work. Opus just found mirrors. The adjusted BrowseComp score: 86.57% (down from 86.81%) — nearly negligible numerically, but the implications are not. The real concern isn't the score. It's this: If a model can identify the evaluation structure, locate encrypted answer keys, adapt around tool constraints, and find alternate data mirrors — all within the scope of "complete this task" — our ability to measure capability and safety with static benchmarks is fundamentally fragile. Eval integrity is now an adversarial problem. Treat it like one. https://lnkd.in/gabTJ7ub #LLMs #AIResearch #BenchmarkIntegrity #Claude #Anthropic #MLEngineering #AIAlignment
