This role is an opportunity to join a dynamic team and contribute to the development of cutting-edge technology.

What You Will Do

• Design, build, and operate large-scale cloud services that run internet-wide and customer-specific scans
• Ingest and normalize third-party threat intelligence, surfacing high-quality findings into underwriting, risk, and security workflows
• Partner with security, product, and data teams to translate detection and scanning requirements into robust, production-ready systems and APIs
• Drive technical excellence and standards in the scanning engine codebase, including code review rigor, design documentation, and best practices for secure coding
• Contribute to architecture and roadmap decisions for the scanning platform, evaluating tradeoffs and proposing solutions that balance speed, quality, and risk
• Diagnose and resolve complex production issues related to scanning performance, accuracy, and stability, collaborating with SRE/Infra teams where needed
• Mentor and support other engineers on the team through design feedback, pairing, and knowledge sharing around systems design and scanning domain concepts
• Own end-to-end systems design for key components of the scanning engine, from initial design through implementation, deployment, and ongoing iteration
• Design and implement high-quality services in Python and Go that power scanning workflows, ensuring code is maintainable, well-tested, and observable
• Improve performance, scalability, and reliability of the scanning engine, optimizing for large-scale, distributed scanning workloads and strict SLAs

What We Are Looking For

• Strong experience as a Senior Software Engineer (or equivalent) working on backend or systems-level services
• Proficiency in at least one of Python or Go, with the ability and willingness to work in both languages over time
• Demonstrated experience with systems design for distributed or high-availability services, including clear understanding of scalability, reliability, and observability
• Hands-on experience building or maintaining scanning, detection, or similar engine-like systems
• Strong software engineering fundamentals: data structures, algorithms, concurrency, and performance optimization
• Experience working in a cloud-native environment (e.g., microservices, containers, CI/CD, monitoring, logging)
• Ability to collaborate effectively across teams, including product, security, and platform/infra, and communicate tradeoffs clearly to technical and non-technical stakeholders
• Proven track record of owning projects end-to-end, from problem definition and design through implementation, rollout, and iteration
• Comfort operating in a fast-paced, evolving environment, making pragmatic technical decisions while maintaining quality and security

Nice to Have

• Experience with code quality practices (testing, static analysis, code reviews) and building maintainable systems
• Familiarity with cybersecurity principles and practices
• Knowledge of Excel for data analysis and reporting
• Experience with agile development methodologies and version control systems (e.g., Git)

Benefits and Perks

• Competitive salary and benefits package
• Opportunity to work on cutting-edge technology and make a real impact in the cybersecurity industry
• Collaborative and dynamic work environment with a team of experienced professionals
• Flexible working hours and remote work options
• Professional development opportunities, including training and conference attendance
• Access to the latest tools and technologies
• Recognition and reward for outstanding performance
• Comprehensive health insurance and wellness programs
• Generous paid time off and vacation policy

• Develop a strong understanding of distributed systems, cloud services, and cybersecurity principles to stand out as a candidate.
• Showcase your experience with Python and Go, and be prepared to discuss your experience with code quality practices and maintainable systems.
• Highlight your ability to collaborate effectively across teams and communicate technical concepts to non-technical stakeholders.
• Be prepared to discuss your experience with agile development methodologies and version control systems.
• Research Coalition's products and services to understand the company's mission and values, and be prepared to discuss how your skills and experience align with these.
• Prepare examples of your problem-solving skills and experience with complex production issues to demonstrate your technical expertise.
