Senior Full-Stack Software Engineer, Discover

We need to output HTML fragment with sections: About the role, Responsibilities (maybe "What You'll Be Doing"), Requirements (maybe "What you'll need to be successful"), Benefits (Compensation & Benefits). Also maybe "About Us" is not needed as it's not a section heading per rules? The instruction: Use

for section headings (e.g. About the role, Responsibilities, Requirements, Qualifications, Skills, Benefits, Pay, Schedule). We should include sections only when posting has real content. The posting includes "About Us" but that's not a required heading; we could include "About Us" as a section? The list of example headings does not include About Us, but we could still use

for any section heading? The instruction says use

for section headings (e.g. About the role, Responsibilities, Requirements, Qualifications, Skills, Benefits, Pay, Schedule). It implies those are typical but not exclusive? Safer to follow the examples: include sections for About the role, Responsibilities, Requirements, Benefits (Compensation & Benefits). Possibly also Skills? The posting includes qualifications etc. We can combine Requirements and Skills into one Requirements section. We must not repeat job title as heading. No Job ID. Remove boilerplate: About Us maybe we can keep as a brief paragraph? The instruction: Remove cookie/navigation/legal/EEO/equal-opportunity/scam-warning boilerplate, duplicated lines, and application instructions. About Us is not boilerplate; it's descriptive about company. Could keep as a

maybe under a heading? But we don't have a heading for About Us; we could just include it as a

before sections. However the instruction says "Use

for section headings (e.g. About the role, Responsibilities, Requirements, Qualifications, Skills, Benefits, Pay, Schedule)." It doesn't forbid other headings, but we should follow that pattern. Probably better to include an

for About Us? Not in list but could be okay. However they said "Use

for section headings (e.g. About the role, Responsibilities, Requirements, Qualifications, Skills, Benefits, Pay, Schedule)." That suggests those are the expected headings. I'd include About the role, Responsibilities, Requirements, Benefits. Also maybe "About Us" as a

without heading. We must preserve all substantive information. So we need to include details from About Us paragraph, role description, responsibilities list, requirements list, compensation and benefits. We must not include filler like "commensurate with experience". Not present. We must not include duplicated lines. Ensure we don't repeat. We must not include application instructions, EEO, etc. Remove lines like "Learn more in our Candidate Hub." etc. Also remove "Learn more Candidate Safety & Interview Process Notice..." etc. We need to output only HTML fragment. Let's extract content: About Us paragraph: "Circle is building the world’s leading AI-powered, all-in-one platform for digital businesses. We make it possible for creators, coaches, educators, and businesses to bring together their audience with engaging discussions, live streams, events, chat, courses, and payments — all in one place, all under their own brand. We’re proud to be a fully remote company of around 270 (and growing!) team members from 30+ countries around the world. We seek exceptional individuals around the world, set them up to do the best work of their lives, and in turn, create a meaningful impact in their own lives. We don't track hours, but we do manage for high expectations very closely. We collaborate across time zones, are highly async, and like to document a lot.

So far, we’ve hosted offsites in Turkey, Portugal, Mexico, Thailand, Colombia, Italy, Ireland, and more, with still more to come! Check out our Careers page for more about working at Circle." We can keep that as a

maybe preceded by an

About Circle? Not required. We'll just put as a

before sections. About The Role heading: "About The Role". We'll use

About the Role

(lowercase? Keep as given). Then paragraph: "We’re looking for a seasoned full-stack engineer to help evolve and expand Circle Discover - Circle’s curated marketplace for finding and buying digital experiences (communities, courses, memberships, and eventually more).
