Job Description

AlphaSense is seeking an experienced engineering leader to own and scale our search platform that powers market intelligence across billions of documents. Youll tackle the challenge of building distributed systems that handle hundreds of queries per second with millisecond latency, while establishing engineering excellence that ensures reliability for our enterprise customers.

This role is perfect for a seasoned engineer who loves large-scale data challenges and has a track record of building robust, high-performance systems. While search experience is valuable, we believe great engineers can master new domains - what matters most is your ability to build systems that scale and dont break.

What Youll Do

Scale Distributed Systems
: Architect and optimize infrastructure handling billions of documents and hundreds of queries per second
Lead Platform Evolution
: Drive the migration from legacy systems to modern architecture, ensuring zero downtime and improved performance
Build Engineering Excellence
: Establish comprehensive monitoring, testing, and deployment practices that catch issues before customers do
Optimize Performance
: Profile and tune systems from the infrastructure to the application level, balancing cost and performance
Drive Technical Strategy
: Own the platform roadmap, making architectural decisions that will scale 10x
Mentor and Lead
: Elevate the teams expertise in distributed systems and large-scale data challenges

What Were Looking For

Required:

12+ years building and operating distributed systems in production
Experience with large-scale data platforms (billions of records) or high-throughput systems (100+ QPS)
Track record of improving system reliability and performance at scale
Deep expertise in distributed systems fundamentals: sharding, replication, consistency, partition tolerance
Strong performance optimization skills - you can profile, diagnose, and fix bottlenecks across the stack
Experience with data pipeline architecture, real-time processing, or database internals
Excellence in building observable systems with comprehensive monitoring and alerting
History of leading technical initiatives and mentoring engineering teams

Preferred:

Experience with search platforms (Vespa, Elasticsearch, Solr) or similar large-scale data systems
Deep knowledge of Kubernetes, CRDs, and infrastructure as code
Background in information retrieval, ranking systems, or recommendation engines
Familiarity with hybrid search approaches (lexical and vector)
Experience with JVM-based systems and tuning
Knowledge of modern engineering practices from high-growth companies

Why This Role is Unique

Youll own a critical platform that directly impacts how customers discover insights. This isnt just about maintaining a search system - its about building the next generation of information retrieval at scale. Youll work with modern technologies (including hybrid lexical/vector search), but more importantly, youll apply your distributed systems expertise to solve fascinating scale challenges.

The best part? Youll join a team of smart engineers who are eager to learn. Your experience in building bulletproof systems will directly elevate the entire teams capabilities.
