🌟 Intro

Founded in 2022,our client is a fast-growing startup backed by strong investors, already working with hundreds of B2B SaaS, including public companies and many unicorns 🦄

We provide an integration platform helping B2B software companies unlock their potential with connectivity. Thanks to a unified API, our clients are able to connect with dozens of financial tools in one click, instead of spending years on development.

Our ambition: become the European leader of financial integration 🚀

🎯 Your Mission

Their platform powers integrations between hundreds of financial software tools. Every API call we miss, every minute of downtime, every botched deploy is felt by our clients (and their SMEs) within seconds.

As our client's first DevOps Engineer, you'll own how we run in production. You'll take infrastructure that today is shared between the founding engineers and turn it into a real, deliberate platform: solid CI/CD, real observability, tight security, and the kind of reliability our fintech clients can build on. You define the function from day one.

👨 💻 Key Responsibilities

You'll work directly with the CTO and the Tech team to make the company’s production-grade at scale.

Own our AWS infrastructure end-to-end

You're the person who knows where every service lives, why, and what it costs. You'll tighten what's there, codify what isn't, and design the next iteration of our cloud architecture as we scale across Europe.

Build CI/CD that engineers actually love

Every commit should ship safely and fast. You'll own the pipelines, the deployment strategy, and the workflow that lets us release multiple times a day without holding our breath.

Bring real observability to the platform

Metrics, logs, traces, alerts. You'll define what "healthy" means for the company and build the dashboards and on-call setup that catch problems before our clients do.

Raise the bar on security and reliability

Fintech clients trust us with sensitive data. You'll harden the platform, put incident response and SLAs in place, and get us audit-ready as we move upmarket.

Lay the foundations, then scale them

You're not just a one-person ops team. You're building the function. Document, automate, set the standards, and over time grow the team around you.

🔎 Profile sought

• Experience: 5+ years of hands-on DevOps / SRE work in production environments, ideally with at least one stage where you owned infrastructure for a small but serious team.
• AWS: Solid hands-on experience running production workloads on AWS.
• Infrastructure-as-code mindset: You codify infrastructure rather than clicking through consoles.
• CI/CD and observability: Comfortable building reliable pipelines and instrumenting services so problems get caught early.
• Security-aware by default: You think about secrets, access management, and compliance as part of the work, not as an afterthought.
• Bilingual: Comfortable working in both French and English. Our team and clients live in both.
• Builder mentality: You're excited by the words "first DevOps hire". You'd rather define the playbook than inherit one, and you know how to do that without breaking what already works.
