Senior tech leadership, inside your team.

For tech-heavy businesses without a senior tech leader: I join for a stretch to build, ship and lead where there's a gap, and leave a foundation that lasts.

Who I work with

Owners, founding teams and heads of engineering at tech-heavy businesses, with a capable team but no senior tech leader to lean on. Things I often hear in a first call:

  • “Our lead developer says the code is a mess, and might leave.”
  • “We need to change direction, but the team isn't on board yet.”
  • “The market is moving and we're not keeping up.”

If that sounds familiar, let's talk.

Outcomes you can expect

Your best people stay

The mess gets a plan, and the people who spotted it get to fix it.

A direction the team owns

A change of course explained, tested and carried by the people who build it.

Faster response to your market

A shorter path from decision to shipped change.

Architecture you can reason about again

The risky parts tested first, before they get expensive.

Leaders who grow into the role

Your managers and engineers learn by working next to me.

AI that helps instead of adding to the mess

Agent tooling where it pays off, with reviews and ownership that keep up.

What I do

  • In-org expert delivery

    I join your high-stakes R&D and product initiatives and do the work with your team: delivering results, earning trust and moving work forward.

  • Hands-on leadership

    As trust builds, I can lead a team, a launch or an engineering practice until you have a permanent owner in place.

  • Team & org design

    Operating rhythms, decision forums, and culture foundations.

  • Investor add-on (optional)

    Selective org, product, and technical diligence for boards and investors.

How we’ll work

Typically, in the first ~90 days I focus on diagnosing friction and creating visible wins: clarifying priorities, restoring pace, and unblocking critical work.

I model durable async practices — written decisions, transparent updates, and knowledge-base loops — so improvements last long after I step out.

My aim is to hire myself out of a job: identify gaps, define roles, recruit, and onboard permanent owners.

Example previous cases

Anonymized. Metrics and references shared in conversation. Today, coding agents make each of these problems grow faster.

Product / R&D rift

“Everything important still ends up on my desk.”
Problem
PMs lacked technical fluency; CTO overloaded with mentoring.
Intervention
1:1s, PM upskilling, R&D coaching.
Result
Respect restored; CTO freed to focus on strategy and fundraising.

Leadership coaching, typically 3–6 months, 4 days a month.

Prioritization chaos at the top

“I keep re-explaining what we should build.”
Problem
CTO struggled to prioritize; strained relationship with tech lead.
Intervention
Mentoring, comms redesign, exec facilitation.
Result
Clearer CEO/CTO interface; re-org enabled CEO to delegate; new exec hire stabilized leadership.

Strategic translation, typically 4–8 weeks, 3–4 days a week.

Senior technical leadership

“Our R&D can't keep up with what the product needs.”
Problem
R&D skills didn't match product needs.
Intervention
New technology foundations, review processes, better hiring rubric.
Result
Higher team velocity; increased product stability; lower customer acquisition costs.

Embedded delivery, typically as interim execution lead for about 90 days.

Decisions evaporating

“Who actually owns what here?”
Problem
Key decisions disappeared without follow-through.
Intervention
Introduced a lightweight knowledge base and written loops.
Result
Durable decisions; smoother collaboration between R&D, sales, and support.

Cross-functional facilitation, typically 8–12 weeks, 2 days a week.

About Raphael Poss

I began my career as a PhD systems researcher with a strong engineering component, then spent over a decade in senior technical and leadership roles at multiple US tech companies. My professional network spans leadership teams across Google, Cockroach Labs, Blacksmith, Datadog, Databricks, Microsoft, Cisco, MongoDB and others.

What I bring to your company through Thaumogen is a mix of research depth and operational experience: the ability to see technical, organizational, and cultural blind spots, and to help you close them while keeping your company focused on growth.
