[Hiring] Senior Software Engineer @Quantum Sky

Role Description

Quantum Sky is searching for a Senior Software Engineer to build and enhance cloud-based and on-premise cybersecurity and compliance applications for highly regulated environments. The ideal candidate is a strong software engineer with experience developing applications in FISMA/FedRAMP environments and familiarity with NIST security and compliance frameworks. They are comfortable owning software across the full development lifecycle—from design and development through CI/CD, deployment, and production operations—and can effectively work across software development, cloud infrastructure, cybersecurity, and compliance.

This role includes work on data-intensive risk and compliance analytics products:

• Applications that ingest security and inventory data from multiple, heterogeneous, and sometimes inconsistent sources.
• Normalize data into a consistent internal model.
• Present risk, gap, and prioritization analytics to different classes of users (executive, program-management, and technical).

Responsibilities:

• Design, develop, test, and maintain full-stack application capabilities with an emphasis on secure, scalable, maintainable, and production-ready software.
• Develop backend services, APIs, integrations, automation, and supporting tools.
• Build new product capabilities and enhance existing functionality across cloud-based/on-premise cybersecurity and compliance applications.
• Work with the Post-Quantum Cryptography Director and cybersecurity subject-matter experts to build software solutions supporting post-quantum cryptography.
• Design and implement integrations with cloud services, security technologies, and third-party systems using REST APIs.
• Develop capabilities that ingest, process, correlate, and present security and compliance information while automating workflows.
• Design data models and normalization/correlation logic capable of reconciling overlapping or conflicting records.
• Design and implement configurable scoring, prioritization, or risk-analytics logic as discrete, testable components.
• Model relationships and dependencies between assets, systems, and organizational entities.
• Implement role-based access control and role-differentiated views for different user types.
• Develop, maintain, and improve CI/CD pipelines and automated deployment processes.
• Build, deploy, and support containerized and cloud-native applications.
• Use AI-assisted software development tools as part of day-to-day engineering workflows.
• Troubleshoot complex application, integration, deployment, and production issues.
• Participate throughout the software development lifecycle.
• Apply secure software development and DevSecOps practices throughout the application lifecycle.

Qualifications

• Demonstrated professional experience designing, developing, and supporting production software applications.
• Experience designing, developing, and consuming RESTful APIs and integrating applications with external systems.
• Experience with relational databases, data modeling, backend application architecture, and modern front-end web development technologies.
• Experience designing and building data-intensive or data analytics applications.
• Experience modeling and querying hierarchical, relational, or graph-like relationship data.
• Experience working within a CI/CD and DevOps-based software delivery environment.
• Experience working with Infrastructure as Code, using technologies to support repeatable and automated deployments.
• Demonstrated experience using AI-assisted software development tools.
• Ability to independently troubleshoot software, integration, deployment, and production issues.
• Strong analytical, problem-solving, and communication skills.
• Comfort operating in a high-ambiguity, early-stage product environment.
• Experience working with Modular Open Systems Architecture relying largely on open-source technology.

Requirements

• Experience developing software for cybersecurity, cloud security, GRC, compliance, or continuous monitoring use cases.
• Experience or exposure related to post-quantum cryptography.
• Experience building data ingestion, correlation, or entity-resolution logic.
• Experience building scoring, prioritization, ranking, or recommendation engines.
• Exposure to graph databases or graph/network analysis libraries.
• Hands-on experience with technologies such as Kubernetes, GitHub Actions, GitLab CI.
• Experience with advanced AI-assisted or agentic software engineering workflows.
• Knowledge of the NIST Risk Management Framework (RMF), NIST SP 800-53 Revision 5, NIST Cybersecurity Framework (CSF), FedRAMP, and FISMA security and compliance requirements.
• Experience translating cybersecurity or regulatory requirements into application features.
• Familiarity with vulnerability management, POA&M management, security controls, evidence collection, and continuous monitoring concepts.
• Familiarity with cryptographic concepts sufficient to work productively with subject-matter experts.
• Experience integrating applications with security tools and other cybersecurity technologies.
• Experience developing and operating software supporting federal government or other highly regulated environments.
• Software development experience with Python or professional experience developing applications using Django or Go (Golang).

Benefits

• Health/Dental/Vision.
• 401(k) match.
• Paid Time Off.
• STD/LTD/Life Insurance.
• Referral Bonuses.
• Professional development reimbursement.
• Parental leave.
