About QOVES

We make software that helps patients and clinics diagnose, plan, and visualize how to improve their appearance. Our AI-driven tools are used by cosmetic medical clinics worldwide. We’re VC funded, profitable, and building the next evolution of our backend platform.

This is a remote role for strong individual contributors. You’ll work alongside our core London team, focusing on executing backend improvements, resolving complex bugs, and implementing new services designed by our architecture group.

We move quickly and value engineers who are meticulous, reliable, and thrive in a structured environment where every week brings a new system to strengthen or untangle.

Your Day-to-Day

• Fix real-world issues: investigate and patch production bugs such as segmentation failures, model timeouts, malformed API payloads, or broken async tasks — ensuring quick turnaround and robust solutions.
• Implement new features and services: turn technical design docs or ADRs into working backend code — whether building FastAPI endpoints, integrating a queue consumer, or wiring up a new AI microservice.
• Refactor and modernize legacy code: take older Django logic and gradually migrate it to cleaner, modular patterns (Celery workers, service boundaries, async APIs).
• Maintain reliability: add metrics, tracing, and error handling so your fixes are observable and measurable in production.
• Participate in small-scale refactors: support the architecture team by executing structured migration tasks (e.g., breaking monolith views into APIs, moving tasks into queues, adding retries).
• Write clean, testable code: follow established patterns, maintain consistency, and document your work clearly for the next engineer.
• Collaborate asynchronously: communicate clearly through PRs, design comments, and Slack updates across time zones.
• Contribute to stability: help improve CI/CD pipelines, identify recurring issues, and propose tactical fixes that improve overall reliability.

What You’ll Work With

• Stack: Python, Django/DRF, FastAPI, Postgres (master + read replicas), Redis, Celery/RQ, RabbitMQ/SQS
• Infra: Docker, Kubernetes/ECS, AWS, GitHub Actions, OpenTelemetry, SigNoz/Grafana
• Tools: Linear, Notion, Slack, internal CI/CD via Dokploy

What You Bring

• 5–10 years of backend development experience in Python (Django/DRF or FastAPI).
• Strong debugging skills — you’re comfortable fixing production issues quickly and safely.
• Experience executing from technical design docs or ADRs and delivering reliable, high-quality code.
• Practical understanding of queues, background jobs, retries, idempotency, and distributed system basics.
• Solid database knowledge — Postgres schema design, migrations, and query optimization.
• Comfortable working asynchronously with teams across time zones.
• Bonus: OpenCV or computer vision exposure, or experience integrating LLM/AI microservices.

What Success Looks Like

• You’ve resolved production issues that previously took hours to debug.
• You’ve implemented a new backend service end-to-end following an ADR.
• You’ve refactored messy legacy code into clean, testable modules.
• You’ve added metrics that make performance bottlenecks visible and actionable.
• You’ve earned trust by delivering stable, maintainable code week after week.

Compensation & Setup

• Competitive global salary
• Equity options
• Performance and quarterly bonuses
• Home-office stipend & hardware budget
• Learning and professional development support

Remote-first. Preference for candidates within ±4 hours of London (GMT).

Applications Closing : 21st Oct

C2 / Native English Required. Your communication skills are extremely important given this a remote role.
