Jobs at Djinni

We're hiring a Software Engineer and Security Researcher to help build our top-tier cybersecurity product. This is a hybrid role by design: a strong software engineer who also brings a deep cybersecurity background. Strong engineering velocity is how features get

shipped; serious security expertise is how those features get shipped right. You should have an understanding of how attackers and defenders actually operate.

The product space is CSPM/CNAPP-related, but extends beyond it. Expect to work across cloud posture, identity, attack paths, prioritization, detection, and adjacent areas as the product

evolves.

The pace is high. AI is part of how we work, every day.

Responsibilities

• Design, build, and ship product features end-to-end: from security research to architecture and production code to release.
• Apply cybersecurity expertise to every feature decision: what to detect, how to model risk, what makes a finding actionable, where customers will be misled by noise, and how to translate raw cloud signal into something a security team can trust and act on.
• Own cloud security capabilities across CSPM and beyond: posture, identity, attack paths, severity/prioritization, detections, and emerging areas of the platform.

• Drive AI into the development loop. Use coding agents and LLM tools as a core part of how you design, prototype, build, debug, review, and document. Write strong prompts,

  evaluate outputs critically, and turn AI-generated work into production-quality code and logic.

• Move fast, with judgment. Make tradeoffs explicit, ship iteratively, and learn from real customer signals.
• Collaborate closely with product, research, and engineering peers: clear written specs, sharp communication, clean handoffs, customer-facing rationale.

Requirements

• 5+ years as a software engineer. You design systems, write production code, reason about reliability and edge cases, and own delivery end-to-end.
• Strong cybersecurity foundation. You understand threats, controls, identity, cloud risk, and why a “finding” is or isn’t worth a customer’s attention. This is what makes your feature decisions land.
• Hands-on experience developing with AI / AI-driven development. This is a MUST. You have meaningfully shipped work where coding agents, LLM tools, or in-IDE AI assistants were a core part of how you built it. You can speak in detail about what worked, what didn’t, and how you got real leverage out of these tools.
• Experience with at least one major cloud platform (AWS preferred; Azure or GCP also valid).
• Comfortable operating at high pace: small batches, fast iteration, willingness to cut scope to ship, calm under pressure.
• Strong communication: you can explain engineering and security tradeoffs to both technical and non-technical stakeholders.

Nice to Have

• Experience building CSPM/CNAPP products, cloud security detection/analytics pipelines, or other top-tier security products.
• Experience building or fine-tuning AI-powered developer workflows: custom agents, pipelines, evals, internal AI tooling, prompt frameworks.
• Familiarity with cloud telemetry/log sources and correlating security signals across configuration, identity, and activity.
• Infrastructure-as-Code (e.g., Terraform) and cloud-native development experience.
• Prior security research background: vulnerability research, threat research, or detection engineering.

On behalf of our Client from France, Mobilunity is looking for a Backend Engineer.

Our client is a table management software and CRM that enables restaurant owners to welcome their customers easily. The app is useful to manage booking requests and register new bookings. You can view all your bookings, day after day, wherever you are and optimize your restaurant’s occupation rate. Our client offers a commission-free booking solution that guarantees freedom above all. New technologies thus become the restaurateurs best allies for saving time and gaining customers while ensuring a direct relationship with them.

You’ll be a core engineer on their API Platform team, the squad that connects their product ecosystem to external partners. The team owns the integrations layer that enables POS systems, marketing platforms, booking aggregators, and other third-party services to sync data reliably in real time. This is a backend-heavy role with high external impact: what you build is used directly by partner engineering teams, and the reliability of your work determines whether customers have a seamless experience or a frustrating one. The primary stack is PHP/Laravel, and you’ll also be expected to contribute to TypeScript codebases when needed.

They are looking for someone who doesn’t wait to be asked. If a sync is failing silently, you spot it and fix it. If a partner integration is fragile, you flag it before it breaks. If a new technology could solve a recurring problem better, you explore it and bring back a proposal. Proactivity is not a soft skill there – it’s a core part of the job.

Requirements:

• 5+ years of professional software development experience, with PHP/Laravel as your primary backend stack
• Deep understanding of REST API design – you’ve built and maintained public or partner-facing APIs and know what good looks like
• Experience with data synchronization patterns: webhooks, polling, event-driven architectures, retry logic, idempotency
• Strong SQL knowledge: you write clean queries, understand indexes, and can reason about query performance at scale
• Proven ability to articulate and justify architectural decisions: weighing trade-offs around reliability, scalability, and maintainability
• Comfortable working in Git-based workflows with pull requests, branches, and CI gates
• Active user of AI development tools (Claude Code, Cursor, Copilot, or similar) — you’ve integrated these into your daily workflow and are curious about pushing them further
• Upper-intermediate to advanced English proficiency

Nice to have:

• Solid TypeScript skills – you can read, write, and review frontend or Node.js code confidently
• Experience with React and/or Next.js
• Knowledge of cloud infrastructure (AWS) and containerization (Docker)
• Familiarity with OAuth2 / OIDC flows and API authentication patterns (API keys, tokens, scopes)
• Familiarity with Keycloak (B2B realm configuration, identity providers)
• Experience with message queues or event streaming (SQS, RabbitMQ, Kafka, etc.)

In return we offer:

• The friendliest community of like-minded IT-people
• Open knowledge-sharing environment – exclusive access to a rich pool of colleagues willing to share their endless insights into the broadest variety of modern technologies
• Mobilunity Medical Insurance program designed to attend our teams’ needs
• Paid vacations and sick leaves, including 5 paid days per year that don’t require a sick note
• Perfect office location in the city-center (900m from Lukyanivska metro station with a green and spacious neighborhood) or remote mode engagement: you can choose a convenient one for you, with a possibility to fit together both
• No open-spaces setup – separate rooms for every team’s comfort and multiple lounge and gaming zones
• English classes in 1-to-1 & group modes with elements of gamification
• Neverending fun: sports events, tournaments, music band, multiple affinity groups
