Tasks

We are seeking a Senior Backend Engineer with strong expertise in building robust, scalable systems and a product-oriented mindset. You will join a small, multidisciplinary team focused on delivering end-to-end backend services that power key user-facing features across our platform.

The ideal candidate is experienced in creating resilient and well-structured services, comfortable working in cross-functional environments, and has a passion for building tools that are both technically sound and usable by non-technical stakeholders (e.g., growth, support, or accounting teams).

While experience in payments or billing systems is a strong plus, this is not a requirement. We welcome backend engineers with diverse backgrounds who enjoy solving complex business problems through software.

This is what you can expect when working with us.

  • Design, build, and maintain backend services powering customer-facing features and operational tooling.

  • Collaborate with engineers, designers, and product managers to shape APIs and flows that are both technically solid and user-friendly.

  • Contribute to internal and external integrations (e.g., cloud marketplaces, partner APIs, or payment providers).

  • Extend monitoring, observability, and alerting across systems to ensure reliability.

  • Drive implementation of backend logic related to reporting, usage metering, entitlements, or similar operational concerns.

  • Translate compliance, analytics, or business needs into sustainable backend architecture.

Requirements

Preferred Tech Stack

  • Backend: Python (FastAPI, Django, Flask, etc.)

  • Databases: PostgreSQL and other relational databases

  • Cloud: Kubernetes, Docker, AWS/GCP/Azure

  • Frontend (optional): Familiarity with React, Vue, or similar reactive frameworks

  • Bonus: Go experience, gRPC, or event-driven systems

What We Value

  • Strong product thinking and ability to translate business logic into code

  • Solid software engineering fundamentals and experience designing scalable systems

  • Comfort working in remote, asynchronous teams

  • Familiarity with collaborative, test-driven development

  • Understanding of distributed systems, data processing, and API design

  • Bonus: Experience in domains such as payments, billing, marketplaces, SaaS usage metering, or reporting

Nice-to-Have

  • Exposure to payments, billing systems, refunds, chargebacks, or fraud detection

  • Background in fintech, eCommerce, SaaS platforms, or internal tools

  • Knowledge of real-time data processing or ML-based decision systems

  • Familiarity with vector databases or search engines

Benefits

  • Competitive salary and benefits package

  • Fully remote and flexible work setup

  • Work on cutting-edge open-source and cloud technologies

  • Collaborate with an inclusive, skilled, and humble engineering team

  • Opportunity to shape scalable systems at the core of modern AI infrastructure
