About the Role

We are building the next generation Cybersecurity Management Platform — a product that unifies security posture and response workflows into a single pane of glass, with LLM-powered automation at its core. We are hiring a Senior Backend Engineer to help architect and build the services that power it.

You will own backend systems end-to-end: from API design and data modeling, to LLM-orchestrated workflows, to production deployment on a modern container platform. You will write code, set the bar for engineering quality, and shape how AI coding agents are used inside our team. This is a high-ownership role for an engineer who genuinely enjoys shipping secure, well-tested software and wants to work on a product where security correctness is a feature, not an afterthought.

What You'll Do

•   Design, build, and operate backend services in Python using Django and FastAPI for our cybersecurity management platform.

•   Architect LLM-powered features using the Anthropic or OpenAI APIs — prompts, tool use, retrieval, evaluation, guardrails, and cost/latency controls.

•   Design clean, well-documented REST and async APIs and the data models behind them; make pragmatic trade-offs between speed, simplicity, and long-term maintainability.

•   Build and operate services as part of a modern microservices architecture, deployed as containers (Docker) and orchestrated with Kubernetes or equivalent.

•   Write secure code by default: apply OWASP Top 10 thinking to every endpoint, review peers' code for security flaws, and partner with security stakeholders on threat modeling.

•   Use Claude Code, Codex, or similar AI coding agents as part of your daily workflow — delegating to them where it accelerates quality, and knowing when not to.

•   Own your services in production: observability, SLOs, on-call, incident response, and continuous improvement.

•   Raise the engineering bar through code review, design review, mentorship of junior engineers, and thoughtful technical writing.

What We're Looking For

Must-haves

•   5+ years of professional backend engineering experience building production services in Python.

•   Strong hands-on experience with both Django and FastAPI — you understand when to reach for each and why.

•   Shipped features that integrate LLMs (Anthropic or OpenAI) into real products — not just demos. You have opinions on prompt design, tool/function calling, evaluations, and controlling cost and latency in production.

•   You write secure code by default and are deeply familiar with the OWASP Top 10 — injection, broken access control, SSRF, insecure deserialization, and the rest. You spot these in code review without being asked.

•   Experience designing and operating modern microservices architectures with container-based deployment (Docker + Kubernetes or equivalent).

•   You actively use and embrace AI coding agents — Claude Code, Codex, or similar — and can speak to how they have changed the way you ship code.

•   Strong grounding in relational databases (PostgreSQL), async patterns, testing, and production observability.

•   Deep knowledge of REST API design — resource modeling, versioning, pagination, error semantics, idempotency — and a point of view on where REST stops being the right tool.

•   Hands-on experience authoring OpenAPI (Swagger) specifications — using them for contract-first design, client and server code generation, and keeping documentation honest as the API evolves.

•   DevOps experience building and operating CI/CD pipelines — GitHub Actions, GitLab CI, or equivalent — with automated testing, security scanning, and progressive deployment to production.

Nice-to-haves

•   Prior experience in the cybersecurity domain: SIEM, SOAR, EDR/XDR, vulnerability management, cloud security, or compliance automation.

•   Experience with event-driven architectures (Kafka, NATS, SQS) and workflow orchestration (Temporal, Celery, Airflow).

•   Experience with retrieval-augmented generation, vector databases, or agentic systems in production.

•   Familiarity with infrastructure as code (Terraform), cloud platforms (AWS/GCP/Azure), and secure SDLC practices.

•   Contributions to open-source Python or security tooling.

What We Offer

•   A senior seat on a small, high-ownership team building a greenfield platform — your architectural decisions will matter for years.

•   A codebase where AI-assisted engineering is a first-class practice, not an afterthought.

•   Competitive compensation, meaningful scope, and a genuine voice in how the product and the engineering org are built.

•   Fully remote work from anywhere in Egypt.

•   A full-time role on a one-year renewable contract — with the clear expectation of long-term continuation for the right person, as the platform is a multi-year commitment.

How to Apply

Send your résumé/CV, a link to code you are proud of (GitHub, a production service you led, or a non-trivial side project), and a short note on one LLM-powered feature you have shipped — what was hard about it, and what you would do differently next time — to career@zettasoft.com.

Zettasoft is an equal opportunity employer. We evaluate applicants on the strength of their work and their fit for the role, and we welcome candidates from all backgrounds.
