Senior Ai Full-Stack Developer - Python / React

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

• 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.
