• With the support of your team’s tech lead and manager, you will break down larger projects into individual tasks, deliver them in multiple phases, and collaborate with others to ensure timely delivery of your work. • You will support your peers and stakeholders in the product development lifecycle by collaborating with product management, design & analytics by participating in ideation, articulating technical constraints, and partnering on decisions that properly consider risks and trade-offs. • You will support the operations and availability of your team’s artifacts by creating and monitoring metrics, escalating when needed, and supporting “keep the lights on” & on-call efforts. • You will contribute to a sense of community on your team by engaging in growth and development activities such as participation in the interview process.

• Work in a multidisciplinary team as a Software Engineer on backend applications, actively participating in discussions, proposals, and planning • Serve as a technical point of reference, resolving critical blockers and providing expert guidance • Participate in the full software development lifecycle, from design to deployment and operation • Apply SOLID principles and Design Patterns in implementation, testing, and maintenance • Develop scalable solutions for millions of users • Communicate effectively and carefully analyze requests from Business and Product teams, among others • Ensure the quality of deliverables • Share knowledge and support the team's development • Conduct code reviews and properly apply test cases • Keep service documentation up to date • Continuously seek technical and performance improvements • Demonstrate willingness for continuous learning and ongoing professional development

• Design and ship a Node.js runtime agent that hooks into the V8/Node lifecycle to trace and block malicious behavior patterns (child_process spawn chains, eval / Function constructors, prototype pollution exploitation, unsafe deserialization, SSRF, path traversal, fs writes to sensitive locations, malicious require() / dynamic import chains, supply-chain poisoning at load time). • Define the detection model: which behaviors are policy-blockable by default, which are signal-only, and how rules are authored, distributed, and versioned alongside our existing Proactive Defense rule pipeline. • Integrate the agent with the rest of the on-host Imunify security stack so that Node.js detections, blocks, and incidents flow into the same telemetry pipeline, the same backend event store, and the same admin UI as our other layers (WAF, host-IDS, brute-force protection, malware scanner, patch management). This ships as a first-class layer of Imunify360, not a standalone tool. • Make it production-safe on shared hosting: low overhead, tenant-isolated, compatible with CageFS / LVE, and resilient to hostile tenants who will try to disable or evade the agent. • Build the pipeline that turns CVE write-ups and threat-intel feeds into shipped detections. The system — not a human — ingests advisories, extracts the exploit primitive, generates and tests rule candidates against a corpus, and rolls them out with the right signal-only / blocking posture. • Own the closed feedback loop from production blocks (true positives, false positives, evasions) back into the next generation of rules.
