Job 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.
