Platform Infrastructure & Data Engineer (Senior/Staff)- Paris - France

SkinBit | Full-time On-Site | Paris

About SkinBit

SkinBit is building a next-generation medical imaging platform for large-scale skin cancer screening. Our system connects on-site hardware devices deployed in clinics with cloud-based services that power data ingestion, processing, clinical workflows, and patient-facing applications.

We operate under real-world constraints: unreliable networks, large volumes of binary data, multi-site deployments, strict security boundaries, and regulatory requirements. Infrastructure and data correctness are foundational to everything we build.

We are hiring a senior Platform Infrastructure & Data Engineer to design, build, and own the data and infrastructure backbone of the SkinBit platform.

The Role

You will own the end-to-end infrastructure and data architecture that connects physical devices in clinics to cloud services and internal applications.

Your responsibility is to ensure that data flows are reliable, secure, observable, and recoverable, even under adverse conditions: intermittent connectivity, partial failures, multi-site rollouts, and evolving regulatory constraints.

This is a systems ownership role, not a DevOps support position. You design it, you secure it, you operate it.

You will work closely with software, hardware, ML, product, and security stakeholders to ensure the platform scales from early deployments to a multi-site production system.

What You’ll Do

Design and Own Platform Architecture

• Design infra-first, data-centric architectures spanning:

  • On-site devices → cloud ingestion → backend services → applications

• Define clear boundaries between edge, cloud, and application layers

• Make pragmatic trade-offs between V0 speed and long-term scalability

Build and Operate Data Pipelines

• Design and operate data ingestion and synchronization pipelines

• Handle large binary data alongside structured metadata

• Define lifecycle strategies for data retention, archival, and deletion

• Design orchestration patterns for ingestion, retries, partial failures, and recovery

Backend Services & Internal Tooling

• Design and build backend web services supporting:

  • Data ingestion and access

  • Internal tools and operational workflows

• Ensure services are observable, debuggable, and production-ready

Infrastructure & Operations

• Own infrastructure as code and containerized workloads

• Manage deployment, upgrades, and environment isolation

• Design systems that support multi-site deployments and geographic expansion

• Own backup, restore, and disaster recovery strategies

Networking & Security by Design

• Design and operate secure connectivity:

  • VPNs

  • Private networking

  • Site-to-cloud isolation

• Enforce security fundamentals:

  • Strong access control and IAM boundaries

  • Secrets management

  • Auditability and traceability

• Build systems assuming zero trust and partial failure

Reliability & Observability

• Own system reliability and production correctness

• Define observability standards (metrics, logs, traces)

• Detect, diagnose, and mitigate failures before they impact users

You Should Have

Background

• Strong experience in platform, infrastructure, or systems engineering

• Proven ownership of production systems, not just design

Core Skills

• Experience designing and building backend web services

• Comfort with distributed systems and failure modes

Security & Reliability

• Experience with secure networking (VPNs, private endpoints, site isolation)

• Familiarity with backup, recovery, and disaster scenarios

• Security- and reliability-minded with a pragmatic product mindset

Tech Stack

• Languages:

  • Python, Go (primary)

  • Bash, Node.js (secondary)

  • C++ (nice to have, especially edge/device-side)

• Infrastructure:

  • Terraform

  • Kubernetes

  • Docker

• Systems:

  • Backend web services

  • Orchestration workflows

  • Data ingestion pipelines

• Networking & Security:

  • VPNs

  • Private networking

  • IAM

  • Audit logging

Seniority
