STATE OF THE SOFTWARE ENGINEERING JOBS MARKET, 2025: WHAT HIRING MANAGERS SEE

The 2025 software engineering job market is experiencing a paradox: companies are receiving a flood of applications (often 1,000+ per role) but are struggling to find quality candidates, with most actual hires coming from sourcing and referrals rather than inbound applications. The market shows increased demand for product engineers and founding engineers, with remote positions facing more competition but offering slightly lower compensation. Also, issues like AI-generated fake applications and interview cheating are becoming growing problems.

NEW YORK STOCK EXCHANGE PARENT COMPANY INVESTS $2 BILLION IN POLYMARKET

Intercontinental Exchange, parent company of the New York Stock Exchange, has invested $2 billion cash into Polymarket at a $9 billion valuation, marking the prediction market's transition from niche crypto platform to mainstream finance. The two companies will collaborate on tokenization initiatives, and ICE will distribute Polymarket's data. The investment capitalizes on growing prediction market enthusiasm as Polymarket became a political reporting staple during the 2024 election, with daily volumes peaking at $400 million, though volumes have since normalized to $40-80 million in early October as the platform and competitor Kalshi blur lines between sports prediction markets and sports betting.

ENGINEERED PROTEIN THAT RESPONDS TO LIGHT COULD HELP RESTORE SIGHT

Science Corp., a Californian company, has created an engineered protein that could help blind people see. The protein, opsin, creates electrical currents when hit with light. Opsins usually need a powerful light source to generate a current, but Science's scientists were able to create opsins that generate an electrical current when exposed to regular indoor lighting. Science is currently building several things, including a device to restore vision and a chip that plugs into the brain using living neurons instead of wires - the new protein could help with both pursuits.

BIRTH OF PRETTIER

It's been almost 10 years since Prettier was released. This post tells the story of its birth and how technological innovation made an underlying source of tension - spaces versus tabs - no longer a thing. Prettier solved formatting, one of the most controversial engineering topics, in the span of just a few years. It is now rare to see a mainstream programming language that does not have a formatter that's widely adopted by its community.
