OneSeven Tech (OST) is seeking an Senior 
Full-Stack Engineer 
to join our team.
We are looking for someone who focuses on building and deploying full-scale applications while leveraging cutting-edge AI tools to maximize efficiency and code quality.
A fast-moving U.S.-based compliance startup is building tooling to help Meta advertisers stay within ad policy guidelines—and avoid costly account suspensions.
The team is mid-way through an ambitious delivery cycle, and we’re looking for a senior engineer to jump in and 
own full-stack features from day one .
This is part of a broader strategy to stabilize sprint velocity, bring in high-signal contributors, and ship production-ready code across both backend and frontend systems.
The Role 
You’ll join a lean, distributed team and play a critical role in delivering features that support advertiser compliance at scale.
Your day-to-day will involve: 
Shipping reliable, production-grade code in 
Python (Flask)
and 
React 
Supporting sprint milestones by building, optimizing, and maintaining platform features 
Integrating with backend task orchestration using 
Celery 
and AI-driven workflows using 
Crew AI 
Work independently, while syncing with team lead and the broader product team.
Owning your output and maintaining momentum across 4–6 sprint cycles 
This is a hands-on IC role for someone who thrives in async teams, can hit the ground running, and cares about velocity 
without compromising code quality .
About You 
You’ve seen what it takes to ship features in fast-paced, distributed environments.
You value clarity, autonomy, and clear ownership.
You don’t need micromanagement—and you communicate well enough to make async work feel seamless.
You’re a calm, focused contributor who enjoys working across the stack and knows how to unblock yourself or others without waiting for standups.
You might be based anywhere in the world, but you’re 
available for collaboration windows with PH or EMEA 
teams and can commit to 
30–40 hours/week 
(with some flexibility).
Requirements 
Must-Have Skills 
5+ years of full-stack experience 
Python (Flask)
– solid production experience 
React 
– can build and maintain dynamic frontends 
Familiarity with 
Celery 
for async task management 
Strong async communicator; can manage own time and unblock sprint delivery 
Comfortable working in distributed teams and adapting to existing codebases 
Bonus Skills 
Experience with 
Crew AI 
or similar AI orchestration tools 
Familiarity with 
Numpy 
or other scientific Python packages 
Understanding of advertising, compliance, or regulated platforms 
Experience in high-trust, fast-delivery consulting or startup environments 
Why This Matters 
Meta's ad ecosystem is both powerful and unforgiving.
Compliance violations can result in 
bans, suspensions, or massive revenue loss 
for advertisers.
We’re helping build infrastructure to protect them—with AI workflows and policy-aware automation.
You’ll help a live product ship faster and better.
You’ll own core parts of the stack.
And you’ll be part of a remote-first team that values delivery over drama.
