Senior Software Engineer

About the Company

At Cyber Guardian Consulting Group, we bring Fortune 100-caliber cybersecurity to small and medium-sized businesses. Since 2015, we've been building proactive, lightweight, and cost-effective solutions that meet and exceed modern security requirements. We're security-forward, AI-first, and obsessed with solving real problems for real clients.

About the Role

This is a senior engineering role. You'll be the first CGCG engineer in London, which means you won't just write code—you'll help shape how we build, hire, and operate as we grow our UK presence. You'll work closely with our US-based engineering and leadership teams while laying the groundwork for what comes next in London.

• Troubleshoot integration failures, API errors, and data inconsistencies
• Work with external vendors and internal stakeholders to understand integration requirements
• Ensure integrations meet security, performance, and reliability standards
• Write clear documentation for integration logic, APIs, and data mappings
• Monitor integrations and improve observability (logging, alerts, retries)
• Help shape engineering culture and hiring as we build out the London team

Required Qualifications

• Strong experience working with REST APIs and JSON/XML payloads
• Proficiency in Python or other backend languages
• Proficient or experienced with cloud technologies such as AWS, Azure, or GCP
• Experience debugging API issues using logs, monitoring tools, and API clients
• Comfortable working with relational databases and SQL
• Strong communication skills and ability to collaborate across teams and time zones

Nice to Haves

• Hands-on experience integrating with third-party SaaS systems (ERP, HRIS, CRM, finance platforms, etc.)
• Working knowledge of frontend programming (JavaScript, HTML, CSS)
• Comfortable working with Excel
• Experience with authentication methods such as OAuth 2.0, API keys, JWT
• IT background with experience supporting, integrating, or administering enterprise software systems
• Exposure to SOC 2, GDPR, or enterprise security requirements
• Experience with Infrastructure as Code (CDK, CloudFormation, or Terraform)
• Knowledge of CI/CD pipelines and deployment automation
• AWS certification
• Comfortable using AI tools in day-to-day work

Why This Role?

• First on the ground – You'll be the founding engineer in London, with real influence over how we grow here
• Ownership – Own major pieces of our integration infrastructure, from architecture to deployment
• High-Impact Work – Your code ships fast and directly supports our clients
• Career Growth – As the London team grows, so do your opportunities to lead it
