About Nexus

NexusOne is the converged data platform for the AI era. Composable by design, built on an open-source foundation, and AI-native from the ground up, NexusOne offers a unified engine for data integrations. Enterprises can bring their existing stacks along instead of rebuilding them, giving AI agents full context across the estate.

What We Stand For

Sovereign data, interoperable systems, decoupled intelligence — delivered the way modern software should be. No rip-and-replace. No multi-year transformation. NexusOne turns the "ball of yarn" of data integrations into a unified engine, less like assembling car parts, more like buying the car ready to drive. With 85+ open-source tools pre-integrated, AI-native automations that deploy and self-heal the stack without human toil, and forward-deployed engineers building shoulder-to-shoulder with customer teams, NexusOne is making a significant impact.

What You'll Do

• Architecture & Technical Farming (65%)
• Hold design authority over NX1 deployment patterns at the customer — attend and actively contribute to architecture review boards, security reviews, and data governance forums
• Design and defend the integration architecture across the customer's data stack: identity federation, CDC patterns, governance metadata, data lineage, network segmentation, encryption
• Identify the next workloads NX1 is positioned to support before the customer has fully articulated them — and qualify those opportunities with stakeholder context and technical depth before handing them to the AE
• Produce high-quality design documents that hold up to hostile review boards without you in the room
• Serve as the technical escalation point when NX1 deployment issues arise at the customer
• Engagement & Commercial Partnership (35%)
• Own the NX1 internal cadence on the account — keep engineering, FDEs, product, and the AE aligned on what's happening at the customer
• Maintain executive-level relationships with customer business and IT leadership at the appropriate cadence
• Translate architectural farming insights into AE-usable expansion theses: technical case, stakeholder map, rough scope, customer political context — qualified opportunities, not loose architectural musings
• Own escalation leadership when something breaks — you're the person in the room
• Navigate vendor governance at a major bank: third-party risk reviews, audit responses, change management, vendor due diligence

Required Experience

• 12–18 years in enterprise data/cloud architecture as an SA, principal engineer, or equivalent
• At least one prior multi-year embedded engagement at a Tier 1 bank or equivalent regulated enterprise — you know what it means to be a vendor inside another organization's culture for 12+ months
• Hands-on or recent hands-on depth in the modern OSS data stack: Spark, Trino, Airflow, Iceberg, Kubernetes, S3-compatible object storage, Kafka — at petabyte scale, with hundreds of pipelines
• Experience producing and defending design documents in front of hostile architecture review boards
• Track record of identifying expansion or net-new use cases through architectural insight at a large customer — named examples of "I saw the customer's next workload before they did, qualified it, and partnered with sales to expand"
• Willingness to be on-site in Charlotte, NC (primary) and NYC (secondary) at 80%+ cadence
• Deep familiarity with bank IT culture and governance: risk and control frameworks, TPRM, change management, audit cycles, regulatory reporting patterns
• Strong differentiators: Prior embedded experience in a highly regulated industry, as a vendor SA Hands-on with relevant workloads: regulatory reporting pipelines, CCAR/DFAST data, AML/KYC, customer 360, treasury and liquidity Open-source contributions in NX1 stack components (Iceberg, Spark, Trino, Airflow) Conference presence at Subsurface, Trino Summit, or Airflow Summit in FS-adjacent tracks
