Interim CTO / Engineering Lead
Embedded interim or fractional engineering leadership for delivery, team structure, technical judgment, hiring, and operating cadence. Usually 2-5 days a week.
THOMAS ÜBERMEIER · INTERIM CTO & ENGINEERING LEADERSHIP
I'm Thomas, a Berlin-based engineering leader with 25+ years behind me. I step in 2 to 5 days a week to run delivery, sort out team structure, and make the technical calls until your permanent leader is in place.
These are the situations where founders and operators usually call me.
I step in as interim or fractional CTO, VP Engineering, or engineering manager when a startup, scaleup, or partner-led engineering team needs senior leadership before a permanent hire is in place.
Fractional & interim CTO in Berlin
Embedded interim or fractional engineering leadership for delivery, team structure, technical judgment, hiring, and operating cadence. Usually 2-5 days a week.
A short diagnostic for founders, investors, or operators who need to know what is broken in engineering and what to fix first.
Senior technical leadership wrapped around nearshore, BOT, satellite-office, or staffing models so the client does not become the project manager.
25+ years in engineering, from production support to running engineering organizations. You work with me directly.
VP & Head of Engineering
Led engineering at two protocol companies (Parity and IOG), taking research-heavy work into production delivery.
Mercedes Pay
Built and ran the IT operations for Mercedes Pay under PCI-DSS Level 1 and GDPR requirements.
ServiceNow & Red Hat
Global infrastructure, data-center expansion, production support, and fleets of tens of thousands of database instances.
Embedded, 2-5 days a week
Delivery, team structure, hiring, and operating cadence for startups, scaleups, and partner-led teams.
I've spent over 25 years in engineering, starting in production support at Red Hat before building the IT operations for Mercedes Pay at Daimler. Later, I moved into Web3 as VP Engineering at Parity and Head of Engineering for the Midnight protocol at IOG (formerly IOHK). My work is about shipping software that works, from stabilizing critical payment infrastructure to taking complex R&D projects to production.
Selling into Europe from the US? European buyers ask for DPAs, TOMs, data flows, and AI governance answers your team can't give cleanly yet. For funded US software and AI startups, I turn those questions into engineering work.
A fixed-scope diagnostic covering data flows, cloud setup, subprocessors, GDPR operations, procurement blockers, and the 30/60/90-day engineering plan.
AI inventory, role and risk classification, documentation gaps, human oversight, logging, vendor dependencies, and the work your product team needs to ship.
DPA, TOMs, subprocessor, data residency, security questionnaire, and architecture answers before a serious European buyer asks for them.
Hiring, EOR, entity, partner, and satellite-office questions translated into technical and organizational tradeoffs, with specialists brought in where needed.
You can answer European buyer, investor, legal, and hiring questions with confidence because the product, infrastructure, and engineering story line up.
I do the job of a CTO, VP Engineering, or Head of Engineering for a defined period: delivery, team structure, technical decisions, hiring, and operating cadence. Where the gap is one level lower, I step in as interim engineering manager. Usually 2 to 5 days a week, embedded with the team. I am based in Berlin and work with teams in Berlin, across Europe, and in the US.
The time commitment. A fractional CTO takes a fixed share of the week over a longer period, often two or three days. An interim CTO or VP Engineering covers the full role for a defined period, usually until the permanent hire starts. I do both, from 2 to 5 days a week, and an engagement can move from one to the other as the company changes.
If the gap is urgent, or you are not yet sure what the permanent role should look like, interim covers it while you find out. I can help define the role and assess candidates, then hand over to the person you hire.
Yes. I built and ran the IT operations for Mercedes Pay, a payment platform operating under PCI-DSS Level 1 and GDPR. That means audit-ready operations: access control, change management, logging, incident handling, and vendor oversight, while the platform keeps running. Fintech and payments teams get an interim leader who already knows what auditors and payment partners ask for.
It means looking at the system, not just the policy. I review data flows, cloud setup, subprocessors, security review artifacts, AI usage, and operating workflows, then turn the gaps into an engineering roadmap.
No. I own the technical readiness and engineering implementation layer. I bring in or hand off to lawyers, DPOs, payroll, banking, and tax specialists where the work is theirs.
No account managers. You talk to me about the actual problem.
