Senior Backend / Cloud Developer (Python, AWS)

Cloud Protection protects Fortune 500 enterprises and government organizations worldwide from malware, phishing, and identity-based attacks in Salesforce. Our work builds on more than 30 years of experience in analyzing malware and defending against advanced threats - expertise few security companies can match.

It’s our people who make that possible. We’re a focused team that moves with the speed of a startup and the depth of decades in cybersecurity. We value passion, purpose, and genuine wellbeing at work, and we’re looking for people who want to set the standard for Salesforce security with us. If that sounds like you, we’d love to hear from you.

You'll join the engineering team building Security Core, the detection platform behind Cloud Protection. It runs in our own AWS environment and analyzes threats in Salesforce, returning the verdicts and intelligence the app enforces as customer policy.

You'll work across the full lifecycle of the platform: designing and building services, putting them into production, measuring how they perform on real traffic, and operating them for reliability and performance.

We work AI-natively. AI-assisted tools are part of how we explore solutions, write and review code, test, document, and improve how we work, and we expect you to use them with judgment, validating what they produce rather than taking it on trust.

Key Responsibilities

• Design, build, and operate the Python services that make up Security Core on AWS
• Build and evolve the detection pipelines that detect malware, phishing, and identity-based attacks
• Implement the metrics and observability that show detection quality, latency, and availability in production
• Drive architecture decisions on scalability, reliability, security, and cost
• Own infrastructure as code and the delivery of production environments
• Build internal tooling for threat analysts
• Work closely with the Salesforce app and threat intelligence teams

What are we looking for?

• Deep engineering fundamentals: solid professional experience in system design, distributed systems, concurrency, and API design. We care more about reasoning from first principles than about familiarity with any particular framework
• Proven ability to design cloud architecture on AWS: choosing the right services and making the trade-offs between scalability, reliability, security, and cost
• Hands-on experience building and operating production services on AWS, including infrastructure as code
• Fluency with AI-assisted development as a daily way of working, backed by the engineering judgment to direct it well and validate what it produces
• Confident Python backend development
• A practical, well-grounded approach to software testing
• Clear communication and the ability to collaborate across engineering, threat intelligence, and product
• Fluent English

A cybersecurity background is a plus, not a requirement. And if you don't tick every box, apply anyway: we value judgment, curiosity, and willingness to learn just as much.

What will you get from us

• Meaningful work with real-world impact - your work helps protect businesses and critical infrastructure from modern cyber threats.
• Flexible ways of working, including up to 30 days per year working abroad and paid sick leave from day one.
• A strong focus on well-being, with mental health support and comprehensive benefits.
• Continuous learning, modern tools, and a people-first culture that values trust and collaboration.
