Python & C++ Software Engineer 3 – Data Access (FIP)
FactSet is seeking a highly skilled and motivated Software Engineer to join our Data Access team — the single, powerful entry point to the FactSet Intelligence Platform (FIP). This is where every interaction begins: AI agents & tools, internal analytics, and client-facing APIs all connect through one unified endpoint and receive responses in a consistent, structured envelope enriched with provenance, source attribution, and entitlement transparency. Operating at the very front of FactSet's data ecosystem, you'll define this client-facing interface and orchestrate the systems behind it, delivering data with exceptional speed, security, reliability, and precision.
The platform handles immense volumes of low-latency requests, so strong engineering discipline is essential — you'll apply best practices in distributed systems, scalability, and performance to build infrastructure that is both resilient and efficient. It's a unique opportunity to shape a critical layer of FactSet's architecture, one that directly shapes the client experience and enables the next generation of intelligent applications. If you're passionate about building high-performance systems, simplifying complex data interactions, and making a measurable impact at scale, we'd love to hear from you.
Responsibilities
- Design, develop, and deploy the Data Access interface that defines how clients access data.
- Implement query patterns and APIs that balance flexibility, performance, and security.
- Enforce entitlements to ensure clients access only authorized data products.
- Build observability into the layer — end-to-end request tracing, provenance, and source attribution surfaced in responses.
- Leverage metrics and KPIs to optimize query execution, incorporating caching and performance strategies to meet client SLAs.
- Own Data Access products and features, driving bug fixes, performance enhancements, and scalability improvements.
- Collaborate with stakeholders and cross-functional teams to continuously improve development processes.
- Participate in a regional on-call rotation to support production systems.
Required Qualifications
- Bachelor's Degree or equivalent in Computer Science or related field.
- 3+ years of software engineering experience with a focus on API development, query systems, or data infrastructure.
- Strong proficiency in Python and C++ with experience building production-grade, client-facing systems.
- Solid understanding of OOP principles and software design patterns.
- Experience with API design and building orchestration layers across multiple backend systems.
- Proven ability to work independently and collaboratively.
- Passion for designing and implementing efficient, scalable, and maintainable software.
Preferred Qualifications
- Experience with multithreaded programming, low latency, and high-availability systems.
- Knowledge of query engine architecture, parsers, compilers and interpreters.
- Experience implementing caching strategies for query results and metadata.
- Experience with service-oriented architecture and microservices design.
- Understanding of distributed systems and handling failures gracefully across service boundaries.
- Experience working with large-scale data systems and balancing latency, throughput, and cost.
- Background with rate limiting, throttling, and client quota management.
