Why us?

Salary in USD.
Bonus system for referrals and sales.
The adaptation period is determined individually for each candidate.

We're looking for an SRE / DevOps engineer to build the reliability layer for a platform that commands live power plants. No unified log pipeline, no dashboard anyone watches, no rehearsed restore - the app runs in production, the layer underneath it is a set of habits. You decide what the observability stack looks like, what an alert may wake a person up for, and how failover is designed and tested.

Second part is physical: with the Infra Lead, dispatch control room - workstations, UPS, local network, secured remote access to plants. Grafana in one tab, a rack in the other.

Must have

• 4+ years SRE / DevOps / systems engineering, Linux daily: services, systemd, storage, performance diagnostics
• Real experience with physical or VPS servers, not cloud consoles only - UPS, RAID, remote management. Cloud-only profile is an automatic no
• Cloud VMs: provisioning, patching, hardening, capacity planning, TLS, nginx
• Docker / Docker Compose in production: dev/staging/prod layouts, registry, zero-downtime deploys
• Observability you built yourself: Prometheus + Grafana or equivalent, log pipeline (fluent-bit / ELK class), and an alerting philosophy you can defend
• Redundancy you tested: PostgreSQL backup/restore and replication, Redis failover, measured recovery. You can describe a backup you personally restored
• Networking: WireGuard or similar, firewalls, DNS, TLS, diagnosing cloud ↔ office ↔ plant links
• CI/CD as code (GitHub Actions or similar), promotion through environments
• Bash + Python for automation
• English B2

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

Preferred Skills (The "Nice-to-Haves")

· Reverse Engineering: Proficiency with IDA Pro or Ghidra to analyze potential conflicts with third-party drivers (e.g., Antivirus conflicts causing the crash).

· x64 Assembly: Ability to read disassembly to pinpoint the exact instruction causing the fault when source lines are ambiguous.

· WHQL/WHCP: Experience with the Windows Hardware Compatibility Program signing process (in case the fix requires re-certification) and Microsoft Virus Initiative program

Job Responsibilities

Write kernel and Driver software that can reach the internals of the operating system.

· Implement novel collection and protection techniques.

· Write robust driver infrastructure.

· Optimize for extreme performance constraints.

· Research uncharted territories of the Windows kernel, drivers, APIs, and internal mechanisms.

· Crash Dump Analysis: Perform deep-dive analysis of kernel memory dumps (Minidumps and Complete Memory Dumps) to identify the root cause of the crash (e.g., race conditions, stack overflows, invalid memory access, IRQL violations).

· Reproduction & Isolation: Design stress tests and verification procedures to reliably reproduce the BSOD in a controlled environment using tools like Driver Verifier and specific load-testing scripts.

· Code Review & Remediation: Audit the existing C/C++ driver code (specifically Minifilter callbacks and process notification routines) for thread safety, proper lock usage (Spinlocks/ERESOURCE), and memory handling.

· Patch Implementation: Implement robust fixes for the identified issues, ensuring zero regression in driver performance or security efficacy.

· Validation: Verify fixes using Microsoft Driver Verifier and HLK (Hardware Lab Kit) basics to ensure stability under high stress.

Department/Project Description

Our clients is an endpoint security company looking for an expert-level Windows Kernel Driver Specialist to assist engineering team in developing next generation Endpoint Detection and Response (EDR) agent. We are looking for an experienced individual to join a team that is responsible for developing our cutting-edge collection, prevention and protection technologies using both documented and undocumented proprietary kernel mode techniques.
The team develops the core kernel technologies for a wide variety of products, from EDR to next-gen AV, including work that encompasses many aspects of kernel development, from infrastructure through filter drivers to function hooking, to name a few.
