We are looking for a Senior Backend Engineer (Python) to join our Nearshore delivery team in Porto, Portugal (Hybrid/Full-time).

In this role, you will work closely with an innovative UK-based fintech startup (founded by former builders from Revolut, Square, and SumUp) to shape, design, and architect high-performance compliance and business verification platforms from scratch.

Key Responsibilities:

• Design, build, and maintain robust, scalable customer-facing REST APIs and backend services using Python.

• Own core product architecture end-to-end, ensuring high availability, performance, and stringent security standards.

• Develop high-performance data ingestion, web scraping, and parsing layers to process real-time data.

• Architect distributed system workflows, including asynchronous processing, queues, pub/sub mechanisms, and event-driven architectures.

• Manage and optimize relational database models (PostgreSQL/MySQL) under high load.

• Collaborate in an agile, product-minded engineering environment, shipping code frequently and driving technical best practices.

• 5+ years of professional backend engineering experience with a proven track record of owning systems end-to-end in production.

• 3+ years of strong hands-on experience with Python (or a similar backend language with total willingness to work primarily in Python).

• Strong fundamentals in distributed systems: asynchronous processing, message queues, pub/sub, idempotency, retries, and eventual consistency.

• Solid experience designing and versioning clean, developer-friendly RESTful APIs.

• Advanced knowledge of relational database modeling and query performance (PostgreSQL or MySQL).

• Comfortable working in Cloud environments (AWS, GCP, or Azure) with CI/CD deployment pipelines.

Nice to Have:

• Experience developing scalable web scrapers and data parsing pipelines.

• Prior experience in regulated/security-sensitive domains (Fintech, KYC/AML, Fraud, Compliance).

• Familiarity with stream processing technologies (Kafka, Pub/Sub, Dataflow, Flink).

• Exposure to low-level languages like Rust, Go, or C++ for performance-critical tasks.
