Backend & Infrastructure Engineer (Go, PostgreSQL, Airflow)
Remote — Europe · Full-time contractor (B2B)
About Soco
Soco is a social commerce scale-up driving hundreds of millions in revenue for e-commerce brands on TikTok Shop. Over 7,000 TikTok Shop affiliates use our iOS app to find top products, land brand deals, and track what's working.
TikTok Shop lets creators earn commissions by promoting products through videos and live streams — content becomes commerce, and creators earn when their audience buys through their links. We make that easier and more profitable.
The role
You'll own our backend infrastructure and data pipelines. Today that work sits with our lead engineer, and it's pulling him away from product — we want someone who takes it properly, makes it reliable, and then improves it.
Concretely:
Run and improve our on-prem deployments (Linux, Ansible, systemd)
Own PostgreSQL: schema design, query performance, migrations, backups
Build and maintain Airflow DAGs for our scraping and data pipelines
Build out monitoring and observability (Prometheus, Grafana) — mostly from scratch
Write and maintain backend services and APIs in Go
Work with QuestDB for time-series data at scale
What we need
Strong PostgreSQL: you've designed schemas, tuned slow queries, and handled migrations on a live database
Comfortable owning Linux servers — deployments, debugging, backups, being the person who fixes it when it breaks
Experience building data pipelines, ideally with Airflow
Go experience, or a backend background (Python, Java, etc.) and the confidence to pick Go up quickly — we'd rather have excellent Postgres and ops skills than years of Go
Good written English and able to work async with a European-hours team
Nice to have, not required
QuestDB or another time-series database · n8n · web scraping, including JS-rendered pages · Prometheus/Grafana · Python
If you haven't touched QuestDB or n8n, that's fine. Anyone who knows Postgres well picks them up in days.
What we offer
$2,500–4,500/month depending on experience, paid as a B2B contractor
Fully remote within Europe
A small team where your work ships immediately and you see the impact
Real ownership of the infrastructure, not tickets handed down to you
