Senior Backend Engineer
Indexed description
As an early-stage startup, we pride ourselves on our ability to roll up our sleeves and build from scratch. You’ll ship code frequently, iterate quickly based on feedback, and still meet the stringent security, performance, and uptime requirements our clients expect.
We all love to build, scale, and grow: our leadership team has a strong track record of building products, scaling teams, and driving growth, and our ambitious engineers join us from leading tech companies and unicorns.
If you’re passionate about turning complex problems into simple, elegant solutions, this role is for you. You’ll have a meaningful opportunity to shape our engineering culture from the ground up.
What You'll Do
- Design and own the core of our platform, from architecture to implementation
- Build a robust, secure, and resilient data ingestion layer capable of handling diverse and high-volume data sources
- Develop a performant scraping and parsing layer to reliably capture and structure data from the web and other external systems
- Deliver customer-facing APIs and developer-friendly documentation that enable a seamless self-service product experience
- Impact and shape the engineering culture, setting high standards for quality, ownership, and collaboration
- Continuously improve our software engineering practices and processes, driving better reliability, scalability, and developer productivity
- 5+ years of backend engineering experience, with a track record of owning systems end-to-end in production
- 3+ years of Python (or a similar language with the willingness to work primarily in Python)
- Strong fundamentals in distributed systems: asynchronous processing, queues and pub/sub, idempotency, retries, eventual consistency, and designing for failure
- Strong experience designing customer-facing REST APIs that are clean, versioned, and pleasant for developers to integrate against
- Strong relational database modelling skills (PostgreSQL or MySQL), including indexing, query performance, and schema evolution under load
- A product engineering mindset: you care about what you're building and why, talk to users, and ship the thing that actually solves the problem rather than the most technically interesting version of it
- Comfort working in a cloud environment (GCP, AWS, or Azure) and shipping reliably with modern CI/CD — without needing to be the team's dedicated platform engineer
- Excellent communication and collaboration skills in a fast-moving environment
- Experience writing web scrapers at scale (anti-bot, proxy rotation, headless browsers)
- Experience with low-level languages like Rust, Go, or C++ for performance-critical components
- Experience with stream processing or high-throughput pipelines (Kafka, Pub/Sub, Dataflow, Flink)
- Experience in regulated/security-sensitive domains (KYC/AML, fintech, fraud, compliance)
- Tackle meaningful problems with real-world impact
- Competitive salary and equity package
- Join us onsite in our offices in Porto
- Flat hierarchy with direct access to the founders
- Top-of-the-line equipment
- Private health insurance, plus sick and compassionate leave as needed
