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 CTO 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
• What We’re Looking For:
• Native-level English (spoken and written); confident leading calls with US clients and executive stakeholders
• 10+ years in senior engineering roles and/or technical leadership (Tech Lead, Architect, Head of Engineering, VP Eng, CTO, Fractional CTO)
• Strong understanding of modern software delivery: web, mobile, APIs, cloud infrastructure, data, and AI
• Proven ability to translate between business and engineering and align diverse stakeholders
• Comfortable with US time zones and communication style
• Highly organized and reliable: you close loops, document decisions, and keep teams aligned
• Able to work independently in a fully remote environment with minimal oversight
• Nice-to-Have:
• Prior experience with US-based clients and enterprise stakeholders
• Background in pre-sales, consulting, customer success, or account leadership
• Experience in FinTech, eCommerce, or AI-enabled products
• Familiarity with security/compliance expectations (SOC 2, data privacy, regulated environments)
• Time & Schedule:
• Part-time: typically 5~10 hours/week (may vary by client load)
• Flexible schedule, with availability for calls in US time zones when needed
• Fully remote - based anywhere

This is a senior, high-trust role: you’ll represent KRON at an executive level for key accounts, and compensation reflects that. We never ask candidates to pay fees or purchase equipment as part of the hiring process.
