Of the ten postings in this thread, nine are software companies chasing familiar patterns — React frontends, streaming platforms, fintech disruption, email clients. Then there's Apollo Fusion, hiring a Power Electronics Engineer to build electric propulsion systems for satellite constellations. This is the most revealing posting because it's a leading indicator of where capital and talent are actually flowing.

The "stack" is the tell. There's no mention of Python, Kubernetes, or GraphQL — because the product is a Hall-effect thruster, not a web app. A Power Electronics Engineer works on high-voltage DC-DC converters, PWM inverters, and the switching circuits that ionize xenon or krypton propellant. The role requires deep expertise in SPICE simulation, magnetics design, and thermal management in vacuum. That the posting doesn't bother listing these tools suggests they're recruiting from a small, self-identifying pool that already speaks the language.

What the brevity reveals about stage. The posting is startlingly terse — two sentences, one email address ([email protected]), no Greenhouse link, no benefits blurb, no "we're changing the world" boilerplate. This screams Series A/B hardware startup: engineering-led, no dedicated recruiter, and confident enough in their mission to skip the sales pitch. The "partial WFH" caveat also reveals the constraint — you can't remote-work a thruster test cell.

The strategic signal. The phrase "big satellite constellations which will deliver internet around the globe" is the giveaway. Apollo Fusion isn't selling to NASA; they're selling picks-and-shovels to Starlink, OneWeb, and Amazon Kuiper. Each of those constellations needs thousands of satellites, each needing station-keeping propulsion. This is a B2B infrastructure play riding the LEO megaconstellation wave — arguably a safer bet than being any single constellation operator.

• Green flag: Onsite Bay Area role with clear customer pull. Hardware startups that survive are the ones with signed purchase orders.
• Green flag: No résumé-keyword theater. They know what they need.
• Red flag: No salary band, no seniority level, no equity signal. For a specialized role, candidates are negotiating blind.
• Red flag: The jobs@ inbox suggests no ATS — expect slow response times and possibly disorganized process.

Compare this to Superhuman ("fastest email client") or Yieldstreet ("democratize wealth") — both are competing in saturated markets with commodity stacks. Apollo Fusion is hiring for a moat that takes a decade of physics training to cross.
