The Role
We're hiring a Fractional CTO to support our internal CTO and serve as a senior technical leader in client-facing engagements. This is a part-time, fully remote contractor role where you'll own high-trust stakeholder communication, help clients make confident product and engineering decisions, and ensure delivery stays aligned with business goals. You'll be the executive-level bridge between clients and our engineering teams—leading discovery, shaping delivery strategy, managing expectations, and translating complex technical realities into clear business outcomes. This is a strong fit if you enjoy consulting-style leadership without taking on a full-time executive role.
What You'll Do
• Lead client-facing technical strategy: join discovery, roadmap, and executive stakeholder calls
• Support the KRON PM by owning portions of account leadership: communication, alignment, escalation management
• Define and validate product direction: clarify goals, scope, constraints, success metrics, and risks
• Shape solution architecture and delivery approach: recommend stack, build vs. buy, integrations, security, scalability, and cost trade-offs
• Translate business needs into engineering execution: create clear epics/user stories, acceptance criteria, and delivery milestones
• Set delivery expectations: timelines, dependencies, risks, and blockers—communicate early and proactively
• Drive clarity and decision-making: facilitate trade-off decisions with non-technical stakeholders and keep projects moving
• Produce crisp documentation: meeting notes, action items, decision logs, and executive-ready status updates
• Improve delivery operations: lightweight process improvements across discovery → build → launch (without bureaucracy)
• Identify expansion opportunities: spot upsell/cross-sell needs (performance, analytics, AI, mobile, security) and support light pre-sales when appropriate
• Build long-term stakeholder trust: become a credible, steady technical advisor for key accounts
