Job Description

As a Senior Product Engineer for PurpleFlow, your mission is to be the primary architect and builder of the engine that powers our next-generation data integration platform. This role is about designing and creating a sophisticated, distributed system from its foundational stages and solving complex engineering challenges at the intersection of workflow orchestration, data processing, and enterprise security.

Your core objectives and ambitions for this role will be : 

• Architect a Resilient Orchestration Engine: You will be the technical owner of the progress of our core ETL engine. Your primary challenge will be to translate visually designed, dynamic user workflows into robust, fault-tolerant, and scalable processes orchestrated by Temporal. You will design the "generic workflow interpreter" that serves as the heart of our platform.
• Master Complex System Interconnections: You will design and build the "connective tissue" of the digital enterprise for our clients. This involves creating a framework of extensible connectors and adapters that can intelligently and reliably interact with a diverse range of systems, from modern REST APIs to legacy databases, with a deep, native understanding of the Odoo ecosystem.
• Solve the Hybrid Cloud & On-Premises Security Puzzle: You will be instrumental in developing our key competitive advantage: a secure, hybrid deployment model. You'll architect the communication protocols and data flow strategies that allow our cloud-hosted control plane to securely manage on-premises workers, ensuring sensitive client data never leaves their network boundary.
• Engineer for True Scalability & Performance: You will design the data passing and processing strategies that allow PurpleFlow to handle everything from low-latency, single-record webhooks to high-volume, multi-gigabyte batch synchronizations. This includes architecting our intermediate data buffering strategy and optimizing for performance across distributed workers.
• Champion a Culture of Quality through Architecture: You will implement and uphold the principles of Clean Architecture and Test-Driven Development (TDD). Your goal is to build a system that is not just functional, but also a pleasure to work on—a system that is inherently testable, maintainable, and flexible enough to evolve with our ambitious product vision.
• Drive the Technical Vision: This is a role with a high degree of autonomy and impact. You will not just be implementing tickets. You will be a critical voice in the R&D process, collaborating directly with the Product Owner to vet ideas, design solutions, and shape the technical roadmap of PurpleFlow, with the potential to grow into a technical leadership position for the entire product.
• Collaboration: Work closely with the Product Owner (Martin), other engineers, and end-users to translate product vision into technical reality and ensure smooth deployment.

Requirements

• ​Professional Experience: A minimum of 3+ years as a Software Engineer, with a proven track record of building and delivering scalable ETL projects or data-oriented products.
• Strong Backend Proficiency (Core):
• Python: Expert-level knowledge.
• FastAPI (or similar): Hands-on experience building modern, asynchronous REST APIs.
• Clean Architecture: A solid understanding of (and passion for) Clean Architecture, Domain-Driven Design, and Test-Driven Development (TDD).
• Solid Frontend Experience:
• React (or similar): Proficiency in a modern JavaScript framework like React, Vue, or Svelte is essential for the full-stack nature of this role.
• ETL & Workflow Automation Expertise:
• Orchestration: Experience with workflow orchestration engines is a massive plus. Temporal is ideal, but experience with Airflow, Dagster, or similar tools is highly valuable.
• Data Processing: Strong understanding of data transformation, ETL/ELT principles, and experience building data pipelines.
• Database Expertise: Proficient in both SQL (e.g., PostgreSQL) and NoSQL (e.g., MongoDB) database systems.
• Odoo Integration Experience: While deep Odoo development experience is not required, hands-on experience integrating with Odoo via its APIs (XML-RPC, ORM methods) is highly important. You understand its concepts and how to get data in and out reliably.
• DevOps & Cloud Mindset:
• Docker: You must be proficient in containerizing applications.
• CI/CD: Familiarity with CI/CD pipelines (e.g., GitLab CI, GitHub Actions) is a strong plus.
• Cloud: Knowledge of cloud services (AWS, Azure, or GCP) is advantageous.
• Communication & Soft Skills:
• Strong verbal and written communication skills in English.
• A product-oriented mindset: you think about the "why" behind a feature, not just the "how."
• Excellent analytical and problem-solving abilities, with a focus on delivering results.
• Highly autonomous, proactive, and capable of managing complex tasks from concept to completion.
• DevOps & Cloud Mindset:
• Docker: You must be proficient in containerizing applications.
• CI/CD: Familiarity with CI/CD pipelines (e.g., GitLab CI, GitHub Actions) is a strong plus.
• Cloud: Knowledge of cloud services (AWS, Azure, or GCP) is advantageous.
