Descripción de la vacante

Dremio is seeking a senior software engineer to lead connectivity work and design scalable, reliable data-access solutions. You will own medium-to-large features, drive architecture discussions, and partner with Product, QA, Support, and SRE to ensure robust, production-ready connectivity across drivers and protocols.

You will diagnose complex failures, mentor peers, and contribute to open-source efforts, while applying best practices in testing, observability, and performance across distributed

Formación

• 8+ years of production software engineering experience or equivalent depth demonstrated through ownership of complex systems and features.
• Deep proficiency in Java, C++, Rust, Go, or other systems languages with ability to work across related languages.
• Experience designing and debugging APIs, protocols, client libraries, drivers, or distributed services; strong knowledge of concurrency, networking and failure handling.
• Experience building unit, integration, and performance tests with CI/CD and release processes.

Responsabilidades

• Own substantial connectivity work: lead features or service components from problem definition through release and handoff.
• Define milestones, acceptance criteria, dependencies, estimates, and risks for complex goals.
• Design scalable, maintainable systems; produce architectural designs and trade-off analyses.
• Diagnose complex failures across client/server, protocols, and distributed systems using logs and telemetry.
• Maintain API and protocol stability; establish compatibility and migration paths for clients.
• Collaborate with Product, QA, Support, SRE, Documentation, and external partners to resolve dependencies.
• Mentor engineers, participate in code/design reviews, and contribute to upstream open-source projects.

About The Role

Dremio's Connectivity team builds the high-performance connectivity solutions that help customers bring data to Dremio and connect Dremio to the broader data ecosystem. The team works across client drivers, protocols, connectors, interoperability, distributed systems, and the reliability and supportability of production data access.

What You'll Be Doing

• Own substantial connectivity work: Lead multiple medium-to-large features or service components from problem definition through design, implementation, validation, release readiness, and operational handoff.
• Turn ambiguity into an execution plan: Define reviewable milestones, acceptance measures, dependencies, estimates, and risks for complex customer, product, and engineering goals.
• Design scalable, maintainable systems: Produce technical designs and architecture diagrams, explain trade-offs, and make feature and service-level decisions across drivers, protocols, client libraries, connectors, and distributed services.
• Diagnose complex failures: Lead root-cause analysis across client/server, protocol, network, authentication, metadata, and distributed-system boundaries using logs, telemetry, profiles, benchmarks, and production evidence.
• Build compatibility and reliability: Maintain API and protocol stability; create automated compatibility, interoperability, performance, scale, reliability, observability, and diagnostics coverage; and define practical migration paths for supported and legacy clients.
• Collaborate and influence: Partner with Product, Query Execution, QA, Support, SRE, Documentation, and external technology partners to resolve dependencies and improve certification, customer experience, and supportability.
• Raise the engineering bar: Participate actively in code and design reviews, mentor and coach engineers, improve team practices, and contribute to relevant upstream open-source projects when aligned with Dremio priorities.
• Use AI-assisted development tools responsibly: Apply Dremio-approved AI tools to code comprehension, debugging, test generation, and documentation while protecting proprietary and customer data and validating results through review, testing, and sound engineering judgment.

What We're Looking For

• Staff-level ownership: 8+ years of production software engineering experience, or equivalent depth demonstrated through sustained ownership of complex systems and multiple substantial team-area features.
• Programming expertise: Deep proficiency in Java, C++, Rust, Go, or another systems or services language, with the ability to work effectively in adjacent languages and frameworks.
• Connectivity and systems depth: Experience designing and debugging APIs, protocols, client libraries, drivers, or distributed services, with strong knowledge of data structures, concurrency, asynchronous programming, networking, and failure handling.
• Problem-solving ability: Able to identify and solve non-obvious problems across client/server and distributed-system boundaries and turn findings into durable fixes and regression coverage.
• Quality mindset: Experience building comprehensive unit, integration, compatibility, performance, or reliability tests and working with production CI/CD, packaging, release, certification, and engineering quality controls.
• Communication and influence: Clear written and verbal communication, including the ability to explain technical trade-offs, surface risks early, align contributors across teams, and influence without formal authority.
• Mentorship: Demonstrated ability to mentor and coach engineers and improve the effectiveness and engineering practices of the team around you.
• Education: Bachelor's degree in Computer Science or a related technical field, or equivalent practical experience. Advanced degrees and equivalent industry experience are welcomed.

Bonus points if you have

• Experience developing JDBC, ODBC, ADBC, or other database drivers.
• Experience with Apache Arrow or Arrow Flight SQL.
• Experience with SQL engines, databases, data platforms, or source connectors.
• BI interoperability experience with Power BI, Tableau, Excel, or similar tools, including collaboration with partner engineering teams.
• Knowledge of OAuth, OIDC, TLS, enterprise authentication, metadata discovery, or query pushdown.
• Cross-platform native build, packaging, release engineering, compatibility certification, or upgrade support experience.
• Observability, production diagnostics, customer escalation, long-running data transfer, cancellation, keepalive, timeout, or proxy experience.
• Contributions to Apache Arrow or other relevant open-source projects.
