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 without rebuilding them, giving AI agents full context across the estate.

We believe in sovereign data, interoperable systems, and decoupled intelligence. Our CEO, Anu Jain, describes our approach as turning 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, we are delivering modern software solutions efficiently.

Our platform processes credit risk data for 90%+ of US small businesses every month, intent signals for 300M+ subscribers monthly for Africa's largest telco, and the data and AI layer for a Top 3 US bank. NexusOne is 100+ people strong, headquartered in Atlanta, and we are tripling revenue year over year, backed by Insight Partners, and running in production in environments most vendors won't touch.

The Role

This is the customer-embedded technical counterpart at one of NexusOne's flagship enterprise accounts. You will be the person the customer's technical organization knows by name—the architect they ping when they have a question, the technical advisor they trust to navigate the daily reality of running NexusOne inside their environment, the NexusOne voice in their architecture reviews, design discussions, and platform decisions.

The role is structured roughly 70% solution architecture and technical advisory + 30% TAM-flavored work (customer-side advisory, internal coordination across NexusOne, escalation routing, technical relationship craft across the customer's engineering org). The 70% is the center of gravity. Credibility is earned through technical depth, not relationship tenure. The 30% is the connective tissue that keeps the role from drifting into pure SA work and ensures NexusOne has a coherent technical voice at the customer.

You will be shaping what "TAM" means at NexusOne, not inheriting a playbook. You'll be shaping the future of how we engage with customers and how we deliver technical solutions.

What You'll Do

• Customer-Side Technical Advisory (70%)
• Be the NexusOne technical voice across the customer's daily technical operations—architecture review boards, security reviews, design discussions, integration planning, platform governance forums
• Hold architectural credibility with the customer's senior engineers, architects, and platform team
• Translate between the customer's technical reality and NexusOne's engineering team—escalations, design clarifications, roadmap requests—without losing fidelity in either direction
• Read design documents and ask the right questions; defend or challenge design choices constructively; produce written technical artifacts the customer's review boards take seriously
• Provide technical context that informs but does not replace the work of the Principal SA (when one is deployed at the same account) and the FDEM (when an engagement is active)
• TAM-Flavored Engagement & Internal Coordination (30%)
• Own the NexusOne-side technical context for each account you cover—keep engineering, FDEs, product, the SAD, and the AE aligned on what's happening at the customer technically
• Route customer-side technical escalations to the right resource at NexusOne (engineering, FDE, Principal SA, DCRE support) without becoming a bottleneck
• Maintain working relationships with the customer's technical middle layer—senior ICs, tech leads, engineering managers—not just the architecture leadership
• Support the AE/SAD on technical pre-renewal conversations and expansion-context preparation, without owning the commercial motion
• Navigate vendor governance at a major enterprise: third-party risk reviews, audit responses, change management, vendor due diligence

Required

• 10–16 years in enterprise data/cloud architecture as an SA, principal engineer, TAM, or equivalent
• At least one prior multi-year embedded engagement at a Tier 1 enterprise customer (bank, top-tier insurer, public-sector flagship, automotive OEM, healthcare system)—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 scale
• Track record of being the customer's technical go-to person at a prior vendor engagement—named examples of "the customer's senior architects asked for me by name on this kind of problem"
• Strong written technical communication—design memos, architecture decision records, exec briefs that hold up to senior technical review
• Willingness to be on-site at the customer in Charlotte, NC (primary) and NYC (secondary) at 80%+ cadence for the WF deployment
• For deployments at large banks: deep familiarity with bank IT culture and governance (risk and control frameworks, TPRM, change management, audit cycles)

Why You’ll Love Working at Nexus

• A collaborative team culture built on curiosity and respect
• Challenging work where your contributions clearly matter
• A leadership team that invests in learning and development
• The opportunity to work at the intersection of cloud, data, and AI innovation
