RYZ Labs is looking for a Senior Full-Stack Software Engineer to join one of our client’s teams, a performance advertising company You’ll ship features into a live PHP monolith that runs a performance advertising business, and you’ll help design the services they break out of it. The work starts in the monolith, because that’s where the business runs today - and the decisions you make there are what the next architecture gets built on.
Basic Qualifications:
- 7+ years building and operating production web applications
- Deep PHP experience in a long-lived, server-rendered application you were responsible for
- You’ve shipped and operated an integration against a major ad platform’s API - Meta, TikTok, Snapchat, or Google/YouTube. We mean the real thing: rate limits and backoff, token rotation, async report jobs, version deprecations, backfilling after an outage
- You can talk credibly about normalizing data across more than one ad platform - where the object models refuse to line up, why the same campaign reports different numbers in two places,



and how you decide which one billing gets to believe
- Strong vanilla JavaScript, and comfort in a modern component framework - you’ll be introducing one, not inheriting one
- You’ve owned a system where a bad change costs real money, and you can talk about blast radius, rollback, and how you verify a data change before you run it
- Self-directed across time zones, and clear in writing

What makes you stand out:
- Production Go
- Background job and queue systems - retries, idempotency, work that survives a reboot
- An understanding of how commercial media-buying automation platforms are built. You don’t need to have built one. We want someone who can reason about how those systems work and what’s worth building versus buying
- Dense operational UI - data grids, bulk actions, review queues, spreadsheet export. This is what our ad ops team stares at all day
- Docker and twelve-factor instincts
- Shipping AI-backed features, no
