CTO-level architecture governance, system evolution roadmaps, and engineering standards embedded into your team on an ongoing basis.
Senior architects who've led systems at scale available immediately
Architecture governance, standards, and design review are either not getting done or handled by someone stretched across multiple other responsibilities.
This engagement fits when:
Warning signs
Architecture decisions made without governance
Teams scaling faster than standards can keep up
No single person owns the system evolution roadmap
Conflicting technical decisions across teams
Regular architecture review sessions where system design decisions are reviewed, risks are surfaced, and technical debt is tracked with intentionality.
A 6–18 month architecture roadmap with decision triggers and options at each point so trade-offs are deliberate, not reactive.
Documented standards for service design, API contracts, infrastructure patterns, testing requirements, and deployment practices. Standards don't slow teams down, undocumented decisions do.
Architecture Leadership includes participation in key design reviews — greenfield services, major refactors, integration decisions. The value is the question that surfaces a dependency nobody had mapped.
Ongoing identification of architectural risk as the system evolves before a scaling event or production incident.
Questions we answer
Who governs architecture decisions as the team scales?
How do you prevent architecture drift across multiple teams?
What standards should be enforced vs. recommended?
When should you build vs. buy vs. integrate?
Architecture Leadership is structured as an ongoing engagement with a defined scope. The Architecture Lead is a senior Kaarastu architect who is embedded into your team's rhythm: attends key technical meetings, is available for async review on significant decisions, and delivers the governance artifacts on a defined cadence.
The engagement can run alongside Execution-phase work or independently. For companies whose primary need is governance rather than implementation, Architecture Leadership can be the entire scope.
A full-time architect costs $280K–$450K/year, takes 3–6 months to hire, and gives you one perspective in one domain. For the first several months, they're learning your system and not governing it.
Kaarastu starts immediately and brings a team at the cost of one architect. Reliability questions get a reliability engineer. Integration decisions get a second opinion. Architecture leadership from a team with diverse scale experience, without the single-hire bottleneck.
Three months. Architecture governance needs time to establish rhythm: the first month is context-building, the second is where the roadmap and standards take shape, the third is where governance becomes operational. After that, engagements typically continue quarter-by-quarter based on need.
Typically 8–12 hours per week, structured around your team's rhythm: attending key technical meetings, reviewing significant design decisions async, and delivering governance artifacts on a defined cadence. The exact split depends on your need and whether you're in a high-activity period like a major refactor or a new product line, or steady-state governance.
Yes, many clients pair ongoing Architecture Leadership with project-based execution — a Platform Engineering engagement, a Modernization programme, or targeted Reliability work. The Architecture Lead provides continuity across those projects and ensures they align with the broader system evolution.
Hands-on coding, day-to-day implementation, and interviews. The Architecture Lead reviews designs, participates in decisions, and documents standards but doesn't write production code. If you need execution capacity, there are separate engagements that can run in parallel.
A senior architect will review your situation and recommend the right starting point.
