Why does Climate Job Radar only read these four ATS platforms?

Greenhouse, Lever, Ashby, and Workable each expose a public, documented job-board API. We never scrape pages behind a login or use private endpoints — only data each company has explicitly chosen to publish.

Does the ATS affect my application?

The ATS determines the form layout and what fields are asked, but the application goes to the same hiring team either way. Applying through the original ATS posting is always preferable to a forwarded link or recruiter intro.

Which ATS is most common in climate-tech?

Greenhouse and Lever dominate venture-backed scale-ups, Ashby is common at fast-growing series A–B companies, and Workable is most popular with smaller teams and European employers.

Why the ATS matters to you

An ATS is the software a company uses to post jobs and manage applicants. Each of the four we track — Greenhouse, Lever, Ashby and Workable — publishes a public job board, which is the only place we read from. We never touch private endpoints or anything behind a login.

For you as an applicant, the ATS is simply where you apply. Knowing which one a company uses tells you what the application flow will look like before you click through.

The four boards

Greenhouse and Lever are widely used by venture-backed scale-ups; their boards list roles with locations and full descriptions. Ashby is common at earlier-stage and fast-growing companies and often exposes structured fields such as employment type and remote status. Workable is popular with smaller teams and across Europe.

All four link out to a standard application form. Whichever board a role is on, applying takes the same shape: open the original posting, complete the form, submit directly to the employer.

Browse companies by their ATS

If you want to follow every climate-tech company on a given platform, browse by ATS. Each ATS page lists the companies we track on it and their combined live role count, refreshed daily.

What the ATS does not tell you

The ATS picks the form, not the role. Salary, remote policy, team size, and growth stage all vary widely within each ATS. Use the company detail page on Climate Job Radar — it surfaces the funding rounds, hiring momentum, and tech stack signals an ATS posting won’t mention.
