About Performics & OneSuite

Performics is the Performance Centre of Excellence within Publicis Groupe, delivering technology, data, and AI-driven marketing solutions for global brands. OneSuite is our unified marketing intelligence and automation platform powering agentic workflows, data processing, analytics services, and channel automation across Search, Social, Programmatic, Commerce, and Measurement.

Backend engineering is foundational across all OneSuite — providing the APIs, integration layers, orchestration runtimes, and backend systems that power every charter, from Agent Studio to AOE, DFP, Channels, and SRE.

We are seeking a Senior Backend Engineer (Individual Contributor) to lead the design, development, and evolution of backend systems across OneSuite.

This is a hands-on engineering role — you will write production-grade code, solve complex distributed systems problems, shape backend patterns, and guide other engineers through technical influence (not supervision).

As a Senior IC, you will help define service architecture, enforce engineering best practices, and collaborate across multiple charters to ensure OneSuite’s backend systems are scalable, reliable, secure, and performant.

Backend Architecture & System Design

• Architect distributed backend services and APIs using Python, FastAPI, Node.js, or equivalent frameworks.
• Design modular, observable, and scalable backend components for orchestration, data services, and platform integrations.
• Define patterns for microservices, domain boundaries, caching, queuing, resiliency, and error handling.
• Build robust service-to-service communication mechanisms (REST, gRPC, event-driven patterns).
• Implement secure authentication, authorization, rate limiting, and multi-tenant access controls.

Hands-On Backend Development

• Write high-quality, maintainable, production-ready code.
• Integrate with external APIs (marketing platforms, cloud services, internal microservices).
• Build and maintain CI/CD pipelines and infrastructure-as-code environments.
• Lead code reviews, mentor engineers, and ensure high engineering standards.
• Contribute to platform SDKs, internal libraries, and backend frameworks used across charters.

Performance, Reliability & Observability

• Implement tracing, structured logging, metrics, dashboards, and alerting.
• Optimize services for latency, concurrency, throughput, and cost efficiency.
• Ensure system reliability through automated testing, load testing, error budgets, and resiliency strategies.
• Partner with SRE to define SLIs/SLOs and improve platform-wide reliability.

Cross-Functional Collaboration

• Work closely with Studio, AOE, DFP, Channel, and SRE teams on shared backend designs.
• Collaborate with Product Managers and UX research teams to translate requirements into backend capabilities.
• Align architecture decisions across charters to ensure consistency and maintainability.

• 6–8 years of backend engineering experience, with architectural ownership over services or distributed systems.
• Expertise in Python, FastAPI, Flask, or Node.js and modern backend development patterns.
• Strong understanding of microservices, concurrency, async programming, and event-driven architectures.
• Proficiency with SQL and NoSQL databases (PostgreSQL, DynamoDB, Redis, MongoDB).
• Hands-on experience with Docker, Kubernetes, and cloud platforms (AWS or GCP).
• Strong CI/CD experience using GitHub Actions, Jenkins, Argo, or similar tools.
• Deep knowledge of observability practices — logs, metrics, traces, performance analysis.
• Proven ability to write clean, testable, well-structured production code.

Qualifications – Nice to Have

• Experience with streaming or queuing systems (Kafka, Pub/Sub, SQS).
• Familiarity with AI/LLM systems (AOE integration), though not required across all charters.
• Knowledge of data engineering patterns or ETL/ELT workflows.
• Prior experience with API gateway architectures, caching layers, or service meshes.
• Exposure to cybersecurity guidelines and secure service building.

Core Competencies

• Technical Expertise: You own backend architecture across services, solving complex distributed systems problems and defining reusable patterns that improve scalability, reliability, and developer velocity.
• Leadership: You lead through influence — mentoring engineers, guiding architectural decisions, establishing engineering standards, and elevating backend craftsmanship without direct people management.
• Product Impact: Your backend systems directly shape OneSuite’s performance, availability, and functionality across Agent Studio, AOE, DFP, Channels, and shared platform components.
• Innovation & Learning: You actively keep up with emerging architecture patterns, cloud-native technologies, and backend frameworks. You introduce pragmatic innovations that deliver measurable engineering and product value.
• Collaboration: You work across charters — Studio, AOE, DFP, SRE, and Channels — aligning backend direction and ensuring platform cohesion. You communicate clearly, build consensus, and drive clarity in complex system discussions.

Why Join Us

• Influence backend architecture across a global-scale AI and analytics platform.
• Remain deeply hands-on while shaping system-wide backend direction.
• Build critical services that power automation, orchestration, and intelligent workflows.
• Enjoy hybrid flexibility, innovative cloud tooling, and growth paths toward Staff Engineer or Principal Engineer.
