About Index Engines

At Index Engines, we're all about helping companies bounce back from cyber threats and trust their data again, no matter what hits them.

Our flagship solution, CyberSense, delivers 99.99% accuracy in detecting data corruption, helping organizations recover quickly from ransomware attacks. We partner with awesome industry leaders like Dell Technologies, IBM, Lenovo/Infinidat, and Hitachi Vantara to power AI-driven cyber recovery across both primary and backup storage.

We're a growing, tech-forward company with a startup feel and an enterprise-level impact. We take our mission seriously, but not ourselves. Expect a team that's collaborative, curious, and loves solving hard problems together.

The Role

We're looking for a Senior Software Engineer to design, build and support the core of CyberSense, our Linux application written in C. You'll own components end to end, from reviewing requirements with Product Management to shipping code and helping customers when something goes wrong in the field.

This is a hands-on role on a Scrum team. Your work directly affects how quickly organizations can find corrupted data and recover from ransomware, so performance, scale and reliability matter. You'll also be a technical leader for small to medium features and the engineers working on them.

This is a fully remote role. You must live in the United States and be able to overlap with teammates in both US and Asia time zones.

What You'll Do

• Design, develop and unit test software components in C for the CyberSense Linux application.

• Build data structures and algorithms that perform well and scale to very large datasets.

• Integrate and test software modules with your Scrum teammates.

• Provide estimates for your work during sprint and release planning.

• Review requirements for new and proposed features with Product Management.

• Partner with QA to review test plans and support testing phases.

• Work with the Support team to analyze and resolve customer-impacting issues.

• Lead the technical direction of small to medium features and the engineers working on them.

What You Bring

• [4+] years of professional software engineering experience, with strong C development on Linux.

• Proven skill building performance-oriented data structures and algorithms that scale to large datasets.

• Experience working in an Agile / Scrum environment.

• A Bachelor's degree in Computer Science or a related field.

• Strong written and verbal communication, especially in a remote team.

• The ability to work independently with minimal supervision in a matrixed organization.

• Flexibility to work across time zones with teams in the US and Asia.

• Curiosity and a real desire to learn new technologies.

We'd Love It If You Have

• Python development experience.

• Experience with git, svn, Jira, Confluence and Bitbucket.

• Linux system administration experience.

• Background in backup software or data protection technology.

• Experience with database management systems.

• VMFS or SCSI development experience.

• Knowledge of communication protocols, server hardware and networking.

• Experience using AI tools such as Claude in your development workflow.

• A Master's degree in Computer Science or a related field.
