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
