[Hiring] Senior Client Partner @OneSix - External

Role Description

The Senior Client Partner is the face of OneSix to our most strategic accounts and the engine behind their growth. It’s an equal mix of being the client’s trusted advisor, OneSix’s business operator, and the internal champion who pulls together the best of our firm behind a single relationship.

• Own a portfolio of high-value accounts, protecting and expanding our footprint, opening new logos, and quarterbacking complex, multi-million-dollar data, AI, and governance engagements from first meeting to long-term partnership.
• Work shoulder-to-shoulder with delivery leaders, alliance partners (particularly Snowflake), and the executive team to ensure every engagement drives measurable outcomes for the client and OneSix.

What You'll Do

• Own your book.
• Take full lifecycle ownership of a portfolio of strategic accounts — protecting revenue, driving organic growth, and opening new logos.
• Be the executive partner.
• Serve as the primary point of contact for our most valued clients, building deep, trusted relationships with CIOs, CDOs, CMOs, Chief Data & AI Officers, and line-of-business leaders.
• Build account plans that actually get executed.
• Design and run plans that expand OneSix's footprint across our AI, Data, and Governance offerings — and put numbers against them.
• Quarterback the big pursuits.
• Lead complex, multi-million-dollar opportunities from first conversation to signed SOW, pulling in solution architects, delivery leads, and partner resources as the moment requires.
• Co-sell with our partners.
• Partner closely with Snowflake, Informatica, AWS, Atlan, Sigma, and others to co-sell, co-develop, and co-deliver strategic opportunities.
• Drive the rhythm of the relationship.
• Lead executive-level QBRs, drive cross-sell motions, and keep a relentless focus on client outcomes and satisfaction.
• Protect engagement health.
• Partner with delivery leaders on scope, margin, utilization, and quality — and spot expansion opportunities before the client has to ask.
• Own the commercials.
• Shepherd SOWs, MSAs, pricing, and scope negotiations in partnership with delivery, legal, and finance.
• Know the client's business cold.
• Build deep fluency in each client's data and AI maturity, commercial priorities, and the executive-level outcomes they're measured on.
• Represent OneSix in the market.
• Show up at client events, conferences, and partner forums as a firm ambassador.

Qualifications

• 10+ years in consultative sales, client partnership, or account leadership. Agency or SI experience is welcome.
• A documented track record of owning and exceeding multi-million-dollar revenue targets in a complex, solution-sales environment.
• Demonstrated ability to architect and close large, multi-workstream engagements for midsize to enterprise clients.
• Deep experience building C-suite relationships — particularly with CIOs, CDOs, CMOs, and Chief Data & AI Officers — and a genuine interest in how data and AI create enterprise value.
• Commercial range: you can lead discovery, shape a pursuit, write a compelling proposal, negotiate a complex SOW, and hold a hard conversation when delivery pressure runs high.
• Exceptional written, verbal, and visual communication skills, with real comfort presenting to executive audiences and authoring executive-ready materials.
• A collaborative operator's mindset — you partner naturally with delivery, marketing, alliances, and leadership to move the firm forward, not just your own book.
• The professionalism, honesty, and integrity we expect of everyone who represents OneSix to a client.
• Bachelor's degree (BA/BS) required.
• Willingness to travel as needed to clients, partners, and OneSix events.

Benefits

• Competitive base salary with uncapped variable.
• Company-paid medical, vision, dental, and wellness benefits for employees.
• Company-provided home office equipment.
• Flexible vacation and sick days.
• A team-oriented, supportive working environment where senior people actually have each other's backs.
• Company-sponsored events and swag (yes, the good kind).
