Senior PHP Developer (Ironwall)

Join the Incogni engineering team to help us scale Ironwall, our specialized protection service safeguarding the online privacy and personal data of vulnerable individuals and public servants. We are looking for a Senior Backend Engineer who thinks in distributed systems, designs for resilience, and takes complete ownership of high-impact technical initiatives.

Our mission is to build a scalable, secure, and resilient platform that supports rapid product growth. You will design core application services, eliminate architectural bottlenecks, and help evolve our tech stack across backend ecosystems.

If you want to

• Partner closely with product managers and stakeholders to analyze business requirements and translate them into clear, scalable technical solution proposals.
• Architect, build, and maintain high-traffic, business-critical backend services with a strong focus on reliability, low latency, and data security.
• Leverage modern AI developer tooling (e.g., coding assistants, LLM-driven refactoring, automated testing agents) to maximize delivery velocity and streamline technical workflows.
• Lead technical decision-making across service boundaries, domain modeling, data persistence, and deployment pipelines.
• Identify performance bottlenecks, optimize database queries, and design robust distributed workflows.
• Drive engineering excellence by conducting high-standard code reviews, establishing testing practices, and mentoring other engineers.
• Own initiatives end-to-end: from initial technical RFCs and system design to deployment, observability, and post-launch stability.

And you can check off

• Senior-level backend expertise: Extensive experience building, scaling, and maintaining production applications using PHP (modern 8.x) and familiarity or willingness to work with languages like Go or Node.js/TypeScript.
• System & API Design: Proven track record designing scalable RESTful APIs, clean domain models, and microservice/modular architectures.
• Data Management: Strong hands-on experience with relational databases (e.g., PostgreSQL, MySQL) including indexing, schema optimization, and caching strategies (e.g., Redis).
• Engineering Ownership: Demonstrated ability to drive projects from concept to deployment, making sound trade-offs between speed, scalability, and technical debt.
• Culture of Quality: Mastery of automated testing (unit, integration, end-to-end), CI/CD pipelines, and writing maintainable, well-documented code.

Bonus points if you

• Experience scaling platforms handling millions of high-concurrency requests or large-scale automated data removal pipelines.
• Deep understanding of observability practices (distributed tracing, structured logging, Prometheus/Grafana).
• Experience with cloud-native infrastructure (AWS, Kubernetes).

Here’s the deal

• Growth and learning opportunities: time dedicated to learning, conferences, online learning platforms, and books for your professional development;
• Health and wellness: we want you to feel and be your best. That's why we offer various benefits, from online workouts, a physical coach and a gym to regular mental health checks;
