#SEN #LI-SC1

We're looking for a Senior SDET who thinks deeply about quality in systems that are inherently non-deterministic. Agentic AI doesn't fail the same way traditional software does — and testing it requires a new toolkit: eval frameworks, prompt regression, tool-call reliability, adversarial scenarios, and more.

You'll own the entire quality infrastructure across our product portfolio — from test data and CI pipelines to the standards and culture of how we ship. You'll work directly with product, devops, and AI engineering, with no layers between your decisions and their impact.

What You'll Own

• Test infrastructure, test data, test processes across the entire product portfolio while working with Devops and Infrastructure engineers
• Test Framework - build and enhance automated testing frameworks and tools that facilitate automated testing across different layers of application.
• The reliability bar for all Web applications, Mobile applications and AI agent outputs — from hallucination detection to latency regressions and tool-call correctness
• Test infrastructure, test data, and test processes across the entire product portfolio, alongside DevOps and Infrastructure engineers
• Automated testing frameworks that span all layers of the application — unit, integration, contract, and end-to-end
• Evaluation frameworks designed for LLM-based systems: non-deterministic output scoring, prompt regression, and adversarial test suites
• HIPAA-aware test data management — de-identification pipelines, synthetic data generation, and audit trail validation
• Integration of automated tests into CI/CD pipelines for continuous delivery confidence
• Build stability monitoring and release gate enforcement before any deployment
• Documentation of test plans, test results, and evaluation standards to support knowledge sharing
• The "safety net" for product quality — you define what done looks like

What We're Looking For

• 8+ years of hands-on SDET experience, with recent work building or testing agentic AI systems (single- or multi-agent) in production
• Experience in healthcare or life sciences — you understand what's at stake when a system fails in this domain
• A true tester's mindset: you seek out edge cases, adversarial inputs, and failure modes others overlook
• Proficiency across the full test pyramid — unit, integration, system, performance, and exploratory — plus familiarity with LLM-specific evaluation approaches
• Strong debugging skills across multi-tier web and mobile architectures; comfortable jumping into production incidents
• Proficiency with testing frameworks such as Jest, React Testing Library, Supertest, and pytest.
• Hands-on experience with testing tools like Cypress, Playwright, Supertest, and pytest (including requests or Selenium-based testing)
• Experience testing RESTful APIs using tools like Postman or Supertest
• Solid command of JavaScript and Python

Bonus Points

• Multi-cloud experience (AWS, Azure, GCP)
• Experience with red-teaming or adversarial testing of AI systems
• Native mobile testing experience (iOS, Android)
• Prior work with 21 CFR Part 11, GxP, or similar regulated-software validation frameworks

Why Medeloop

• Ownership from day one: small team, high-trust, no layers between your work and its impact
• Technically ambitious: you'll build AI-powered workflows, not just support them
• Real-world stakes: your work accelerates drug development, addresses health equity, and improves clinical research for institutions that matter

Strong foundation: Series A, top-tier investors, and a data asset (200M+ patient records) that most companies spend years trying to build

Our iOS application is at the heart of Poka’s mission. Deployed globally, it supports frontline workers every day in manufacturing and food production environments, helping them learn, collaborate, and solve problems in real time.

We are looking for a Mobile Developer to join our squad. In this role, you will be a key contributor to our established and robust iOS ecosystem. While you will spend significant time working within our native Swift environment, you will also help us explore and implement modern cross-platform efficiencies. We are beginning to strategically integrate React Native for specific new features, and you will play a vital role in determining how these two worlds best interact.

Why this role?

• A core product with global impact: You will work on Poka’s flagship mobile application, used daily in manufacturing environments around the world.
• Meaningful technical influence: You will actively contribute to architectural decisions and long-term mobile direction. Your perspective will help shape key technical choices.
• An exciting technology transformation context: You will participate in the evolution of our mobile strategy,
• An environment that values expertise: We value autonomy, collaboration, and the ability to step back and think critically. Here, senior experience truly makes a difference.

What you’ll be doing:

• You will be the point person for mobile within your squad, maintaining and expanding a high-scale native application used by major global manufacturers.
• We aren't doing a "rewrite." You will help us identify high-impact opportunities to use React Native for new UI/UX components while keeping the core of the app natively performant.
• You’ll work in a multidisciplinary team (FE, BE, QA, Design) that operates with a startup mentality. You have the freedom to influence your squad’s technical roadmap and daily processes.
• We are actively leveraging AI tools (like Claude) to accelerate our development. You’ll help us bridge the gap between native Swift patterns and more AI-friendly web-standard architectures.

What we’re looking for

Required

• 4+ years of experience in native iOS development using Swift
• Strong knowledge of Apple technologies (Swift, UIKit and/or SwiftUI)
• Excellent written and spoken communication skills in both French and English
• Experience building client-server applications

Strong assets

• Experience with React Native
• Participation in a native-to-cross-platform migration (optional)

Who you are:

• You can analyze technical trade-offs and clearly articulate your recommendations.
• You are comfortable constructively challenging existing approaches.
• You prioritize simplicity, maintainability, and code clarity.
• Your technical decisions are guided by product value and user experience.
