At Veriff's Biometric Solutions team, we are trying to prove, in real time, that the person on the other side of the screen is real and who they claim to be. Our ML-powered platform uses advanced image recognition, facial verification, face recognition, facial anti-spoofing (liveness detection), and behavior analysis to make identity decisions.

We're looking for a Senior Software Engineer to help build and scale our real-time verification services, with security, scalability, and maintainability at the core.

You'll help us protect honest people online by:

Owning the design and evolution of the architecture for a strategically critical product area, making the calls that shape scalability, security, and maintainability for years
Leading transformational architecture work: real-time matching at scale, resilient event-driven services, and the CI/CD and observability foundations that make them dependable
Setting and raising engineering standards, and mentoring and growing the engineers around you
Partnering closely with other engineers, ML data scientists, and specialists to turn complex identity problems into working products, and driving cross-functional alignment with product and dependency teams
Building scalable, maintainable APIs and event-driven services that other teams and external customers depend on

You are the right future Veriffian if you have

Over 5 years of experience building and operating large-scale applications (ideally in Python)
Deep expertise in distributed systems, modular design, and SOLID principles, with a track record of architectural ownership
Experience building scalable, maintainable APIs and working with message-queuing concepts
Fluency with CI/CD, monitoring, and what it takes to run reliable, high-throughput services in production
Comfort with a range of testing strategies for robust, reliable software
A working understanding of relational databases and structured logging systems
Strong communication and influencing skills, able to align engineers and non-engineers around a technical vision
A self-starter mindset that balances both tech and product decisions to come up with a balanced outcome for both customers and engineers.
A history of mentoring engineers and explaining your solutions to non-engineers

Nice to have:

Some experience working with mobile SDKs (iOS, Android) or Web in React
Previous experience working on a B2B/SaaS product
