Senior Backend Developer



We operate at consumer scale, protecting millions of people every day across devices, accounts, and digital touchpoints. In a world where phishing, fraud, and AI-powered scams evolve overnight, Guardio stays ahead of the curve.

We move fast, think deeply, and build with purpose. Our culture is rooted in transparency, feedback, and collaboration along with shared wins, team dinners, company trips, and good times.

So, what's the job?



We are looking for a Senior Backend Developer to join our R&D team!

You will:

• Join a core team of experienced engineers to design, develop, and maintain scalable backend services using Python and Golang.
• Collaborate with amazing people across multiple departments—DevOps, product management, cybersecurity, and more—to build robust solutions.
• Build production-grade systems that tackle high-scale, low-latency challenges, processing petabytes of data and handling 30K+ requests per second.
• Define architecture, quality standards, and best practices while delivering simple, high-quality, and well-tested code.
• Continuously explore new technologies—from cloud platforms and containerization tools like Kubernetes to big data systems like BigQuery—to drive innovation.

Well, our guess is you have a good chance of being that person if you check as many of these as possible:

• 5+ years as a backend developer, building production-grade systems from initial commit to launch using Python and Go.
• Proven track record in designing scalable systems with RESTful APIs, microservices, and distributed architectures using relational and NoSQL databases.
• Skilled in leveraging cloud platforms to create high-performance, low-latency solutions.
• A strong team player with excellent communication, thriving in agile, cross-functional environments.
• Bonus: Experience with BigQuery, open source contributions, and a solid understanding of web cybersecurity vulnerabilities and attack surfaces.

Don't mind if we do. Our tech stack:

• Python
• Go
• GoogleCloud using K8S
• MySQL + Redis + BigQuery
• Thinking of a great addition? Let's do it.
