Beyond is a technology consultancy helping organizations thrive in a rapidly changing world.

We build, modernize, scale, and operationalize technology, creating Cloud and AI solutions to unlock productivity and drive customer growth.

Role Overview

• We’re looking for a technical leader to shape the next generation of intelligent search systems. This role offers the opportunity to define architectural strategy, lead transformative initiatives, and work at scale on search platforms infused with machine learning and semantic intelligence.

As a Principal Engineer at Beyond, you’ll:

• Lead the architecture and evolution of scalable, high-performance search backend systems, including indexing, query processing, ranking, and retrieval.
• Drive cross-functional initiatives to integrate modern search technologies such as semantic search, vector-based retrieval, and large language model (LLM) enhancements.
• Define strategies to enhance the performance, reliability, and observability of search services, ensuring low-latency, high-availability systems.
• Design and implement frameworks for evaluating search quality through both offline metrics and live A/B experimentation.
• Champion engineering best practices and mentor engineers across teams, raising the bar for code quality and system design.
• Shape long-term technical direction by staying ahead of trends in AI, ML, distributed systems, and search technologies—and bringing these innovations into production.

Things that will make you stand out:

• Degree in Computer Science, Engineering, Machine Learning, or a related technical field.
• 8+ years of experience designing and leading the development of large-scale distributed backend systems.
• Hands-on experience with search infrastructure or recommendation engines is a strong advantage.
• Deep familiarity with technologies such as Apache Beam, Pub/Sub, Redis, and other large-scale data processing frameworks.
• Proficient with ElasticSearch and similar search platforms, as well as both SQL and NoSQL databases.
• Demonstrated experience building robust APIs (REST, GraphQL) and operating in modern cloud environments (GCP, AWS), using Kubernetes, Docker, CI/CD, and observability tools.
• Proven ability to lead and influence engineering direction across teams and functions.
• Strong communication skills and the ability to align diverse technical stakeholders around a cohesive vision.

Nice to Have

• Specialization in search-related ML areas such as semantic search, vector retrieval, NLP, or recommendations.
• Experience integrating LLMs, developing custom model architectures, or deploying machine learning solutions in production.
• Knowledge of end-to-end ML system design, including experimentation workflows and model lifecycle management.
