Description

We're looking for a Full-Stack Developer & Data Engineer to join the team behind **Pulse** , our multi-tenant Business Intelligence platform for the hospitality industry. Pulse serves 10,000+ users across corporate, regional, and property levels through five product lines (Insight, Plan, Pro, Rate, and Shift). This is a hybrid role: you'll split your time between building the applications our clients use every day — Angular/TypeScript for web and desktop, React for mobile — and designing the ETL pipelines and ClickHouse data models that power the analytics behind them. Roles/Responsibilities Full-Stack Development - Design and build features across our Angular/TypeScript front end (web and desktop, backed by Express.js) and our React-based mobile app. - Contribute to our subdomain-based multi-product architecture (one Angular app + Node.js backend, database-driven feature registry, shared sessions across subdomains). - Maintain and extend current features, including dashboards, reporting, and data visualizations. Data Engineering & ETL - Design, build, and maintain ETL pipelines that bring hotel reservation, rate, and competitive-set data from a variety of external sources into our ClickHouse Cloud warehouse. - Model and optimize ClickHouse schemas (ReplacingMergeTree / AggregatingMergeTree, partitioning, projections, materialized views) for fast analytics at scale. - Write and tune SQL across ClickHouse and MySQL (Azure) to support reporting and dashboarding needs. - Diagnose and resolve data pipeline issues and query performance bottlenecks using EXPLAIN plans and query logs. - Ensure data accuracy through regular audits, validation, and quality checks. Support & User Requests - Act as a technical point of contact for property and corporate users, responding to support tickets and troubleshooting reported issues. - Triage user questions and feature requests submitted through our helpdesk/ticketing tools, resolving them directly or routing them to the right team. - Determine whether a reported issue stems from the data, the application, or infrastructure, and drive it to resolution. - Communicate clearly and patiently with non-technical users throughout the process. Infrastructure & Collaboration - Work within our Azure-hosted infrastructure (Container Apps, Blob Storage, Data Factory) and Google Cloud Storage integrations. - Maintain CI/CD pipelines (GitLab), process management (PM2), and our Redis caching layer. - Collaborate with analysts, product, and other stakeholders to translate business and data requirements into technical solutions. - Implement data security and access controls to protect sensitive client data. - Stay current with emerging trends in both data engineering and front-end development. Требования: Nice to Have Bachelor's or Master's degree in Computer Science, Information Technology, or a related field (or equivalent experience). Background in hospitality, BI, or SaaS analytics products. Experience with GitLab CI/CD, Redis, PM2, or Google Cloud Storage integrations. Required Proven experience as a Full-Stack Developer and/or Data Engineer — ideally with hands-on experience in both. Strong SQL skills, including experience with a columnar/analytical database (ClickHouse strongly preferred; MySQL, Azure SQL, or Oracle also relevant). Solid experience with Angular and TypeScript on the front end, and [link] on the backend. Working knowledge of Python for scripting and data processing. Experience with React for mobile app development. Experience with cloud infrastructure, ideally Azure. Strong problem-solving skills and comfort working in a fast-paced, collaborative environment. Excellent communication skills, with the ability to explain technical concepts to non-technical stakeholders. Fluent English; French is a plus. The description of functions is merely indicative and not exhaustive. Accordingly, the employee shall perform any other duties inherent to the labour position and their professional group, in accordance with the company's directives.
