Interim / Fractional Technical Leadership

Interim leadership that turns strategy into shipped outcomes

FelixSchallerCOM provides interim and fractional technical leadership for autonomy and AI organizations, as well as PE-backed portfolio companies. I step in as a pragmatic technical lead, for example Fractional CTO, VP Engineering, or Chief Architect, to bring focus, structure, and momentum: aligning product and engineering, strengthening architecture and delivery, de-risking critical programs, and building the operating system your team needs to ship reliably and scale.

I help leadership teams translate priorities into an executable plan and a delivery cadence that works. Typical engagements include stabilizing the roadmap, clarifying ownership, improving engineering velocity and quality, and making technical decisions that withstand scale and safety requirements. You get senior leadership support without a long hiring cycle, with clear accountability, measurable progress, and a smoother path from prototype to production.

Senior technical leadership, exactly when you need it

1. Roadmap and delivery operating system. Set priorities, delivery cadence, metrics, and governance to ship predictably.
2. Architecture and production readiness. Make key technical decisions, reduce technical debt, and harden the stack for deployment and scale.
3. Team structure and engineering leadership. Clarify ownership, strengthen the engineering organization, and coach the team.
4. Quality, V&V, and safety readiness. Strengthen testing strategy, validation evidence, and safety and compliance workflows where relevant.
5. Program recovery and risk management. Unblock critical initiatives, handle dependencies, and stabilize timelines when projects are off track.
6. Portfolio value creation support (PE). Translate diligence findings into a 100-day plan and execution roadmap with clear ownership and milestones.

How we work

1. Rapid assessment and alignment. Understand the business goals, delivery reality, and the highest-risk bottlenecks, then align leadership on priorities.
2. Plan, governance, and operating cadence. Establish a practical roadmap, decision process, KPIs, and weekly cadence to track progress and remove blockers.
3. Execution leadership and team enablement. Lead key decisions, coach the team, and drive critical workstreams, improving velocity, quality, and ownership.
4. Handover and scaling the system. Document decisions, stabilize processes, and transition ownership so the organization keeps improving after the engagement.
