Job description

Liferaft is looking for a highly skilled and visionary Full-Stack Engineer to play a critical role in building on the already sophisticated open source data collection capabilities we have. This role will be hybrid in Halifax, NS, or fully remote within Canada and must sit in either the Eastern, or Atlantic time zones.

This role will partner closely with the wider engineering leadership, Manager, Data Acquisition and core product engineering teams to create new data integrations and further enhance existing ones to continue improving the quality and breadth of data we provide.

What you do as the Full-Stack Engineer at Liferaft

As a Full-Stack Engineer at Liferaft, you will play a central role in building and maintaining the technical foundation of our threat intelligence platform. While your work may occasionally touch the front end, your primary focus will be on data ingestion, backend services, and scalable infrastructure—bridging the gap between raw data and actionable insights.

• Design, implement, and maintain scalable backend services that integrate with a wide range of third-party APIs, handling real-time and batch data ingestion from diverse public sources.
  
• Develop and optimize data pipelines and database architectures using MySQL and Elasticsearch to ensure accurate, high-performance access to structured and unstructured intelligence data.
  
• Build and maintain event-driven systems using technologies like Kafka or RabbitMQ to support asynchronous processing and resilient workflows.
  
• Contribute to front-end development efforts using modern JavaScript frameworks (e.g., React), ensuring seamless user experiences and integration with backend systems.
  
• Work closely with product, data, and design teams to translate user and business requirements into functional, reliable, and secure product features.
  
• Participate in code reviews, architectural discussions, and process improvements to maintain a high standard of engineering quality.
  
• Stay up to date with emerging technologies and bring forward ideas to improve our platform's scalability, performance, and reliability.
  
• Collaborate with engineering leadership to help shape the technical direction of the OSINT platform in alignment with Liferaft’s mission and customer needs.

What You Need to Get the Job Done

Technical Experience

• At least 5 years of professional experience with modern programming languages such as Python, or PHP, with a strong emphasis on third-party API integration (REST, GraphQL, OAuth).
  
• 5+ years of experience working with MySQL, including expertise in schema design, query optimization, and data modeling for high-performance applications.
  
• 3+ years of hands-on experience with Elasticsearch or similar full-text search technologies, including index tuning and query DSL usage.
  
• Experience working with both structured (e.g., SQL, JSON) and unstructured data (e.g., HTML, PDFs, social content).
  
• Experience implementing or maintaining messaging/event-driven solutions using technologies such as Kafka or RabbitMQ.
  

Full-Stack Competency

• Familiarity with front-end frameworks like React or Vue.js is an asset.
  
• Comfortable with API-driven front-end development and working across the full stack when necessary.
  

Collaboration and Problem Solving

• Demonstrated ability to work cross-functionally with data, product, and infrastructure teams to deliver reliable, scalable solutions.
  
• Strong critical thinking skills with a track record of solving complex engineering challenges creatively.
  
• Self-motivated with a passion for continuous learning and staying current with new technologies and frameworks.
