DiaMonTech's posting is the most revealing in the batch because it exposes the strange collision between deep-science hardware R&D and generalist software hiring. They're a Berlin-based, VC-backed team building a non-invasive blood glucose monitor using photothermal spectroscopy — a technique that fires infrared light at skin and measures thermal response to identify molecular signatures. That's Nobel-adjacent physics being productized for a market (diabetes monitoring) currently dominated by Abbott's Libre and Dexcom's CGM.

The tech stack silence is the signal. Notice what's missing: no language, no framework, no cloud provider, no mention of embedded systems, DSP, firmware, or signal processing. For a company whose entire moat is turning raw spectroscopy data into a clinical-grade glucose reading, that omission is astonishing. Either:

• They're hiring for the companion app / cloud backend layer (patient dashboards, HCP portals, regulatory data pipelines) and the hard-science software lives with the physicists — which would mean this is a much less interesting role than the pitch implies, or
• They genuinely haven't decided their stack yet, which for a medtech company approaching clinical trials is a red flag on engineering maturity.

What the pitch reveals about stage: They lead with founder credentials ("world-wide renowned professor of bio-physics" plus a "serial entrepreneur") rather than product traction, revenue, FDA/CE pathway, or clinical data. That's classic Series-A-or-earlier deep-tech positioning — the science is the asset, the commercial story is still forward-looking. The ONSITE / PARTIAL REMOTE Berlin requirement further suggests a small team that needs hands on the hardware.

Skills trend highlighted: The broader signal is the continued rise of "software eating medical devices." A decade ago, a glucose monitor was firmware + a screen. Now it's a data platform: continuous readings, ML-based trend prediction, EHR integration, insurance-grade auditability. Even companies whose differentiator is physics now need general-purpose software engineers, not just embedded specialists.

Red flags: Truncated posting (cuts off mid-sentence about the founders), no salary band, no mention of regulatory approach (IEC 62304? ISO 13485?), no clarity on what "Software Engineer" actually builds. For a medtech role, the absence of any compliance language is telling — either they haven't reached that maturity, or they're hiding the burden from candidates.

Green flags: Genuinely novel science with a huge TAM, Berlin location (strong deep-tech ecosystem, lower burn than SF), partial remote option, and VC backing means runway.
