Staff Software Engineer – Full Remote or Hybrid (m/f/d)

Job Description

Your Mission

As a Staff Software Engineer , you’ll operate at org‑level, shaping the technical direction of multiple domains and raising engineering standards across the organization. You’ll partner closely with Product, Data, and Tech teams to deliver measurable impact and help us scale reliably and efficiently.

Your key responsibilities will include:

• Architect the Future : Design distributed, stateless, and scalable systems that are resilient to failure and aligned with long‑term business and technical strategy.
• Stay Hands‑On : Actively contribute to the codebase, prototype, implement, and review critical features. Lead by example through high‑quality, pragmatic, and scalable code.
• Scale What Matters : Leverage asynchronous architectures and message‑driven patterns using technologies like Kafka, RabbitMQ, SQS, or pub/sub to improve latency, responsiveness, and decoupling of services.
• Ensure Consistency and Integrity : Define and implement patterns for data consistency (eventual or strong), message ordering, and reliable state transitions across services and storage layers.
• Be a Multiplier : Mentor engineers across teams, level up engineering capabilities, and help embed a culture of technical excellence and ownership.
• Raise the Bar : Promote best practices in testing, observability, continuous integration, and secure software development.
• Transform at Scale : Actively reduce technical debt and drive modernization strategies that improve system agility, performance, and reliability.
• Partner for Impact : Collaborate with Engineering Managers, Product, and Infrastructure to influence roadmaps and shape a pragmatic, scalable architecture vision.

Qualifications

Your profile:

• Proven experience designing and delivering robust, distributed, and mission‑critical systems in production.
• Expertise in asynchronous processing and message‑driven systems using technologies such as Kafka, SQS, RabbitMQ, or pub/sub.
• Deep technical fluency in system design, performance tuning, concurrency, and consistency models.
• Strong coding skills in one or more modern languages (e.g., Java, Go, Python, TypeScript).
• Familiarity with service‑oriented and event‑driven architectures, eventual consistency strategies, and data synchronization mechanisms.
• Mastery of CI/CD, test automation strategies, and infrastructure‑as‑code tooling.
• Hands‑on experience with secure coding practices and awareness of compliance and resilience in regulated or complex environments.
• Strong observability mindset: metrics, logs, traces, incident handling, and root cause analysis.
• Fluent in English & French.

Leadership Competencies

• Ability to lead technical direction across multiple teams without relying on positional authority.
• High judgment in balancing engineering purity with speed, business outcomes, and risk.
• Experience mentoring Senior Engineers and guiding architectural decisions at the org level.
• Ability to navigate ambiguity, influence without ego, and coach others through technical complexity.
