Software Architect

Backend Architect (AI-Native Enterprise Platform)

Harrison Clarke is partnering with an exceptional founding team to build the engineering core of a new category-defining company: an

AI-native, agentic system of record for enterprise operations

.

This is not an incremental SaaS product. It’s a ground-up reimagining of how complex enterprise systems are built, operated, and experienced - replacing brittle workflows, heavy implementation layers, and admin overhead with

self-managing, agent-driven infrastructure

.

The company is backed by

leading venture firms

and founded by a rare combination of

former enterprise platform leaders and deeply technical architects

who have built and scaled mission-critical systems from first principles.

We are hiring the

Founding Backend Architect,

a true peer to the CTO, to help design and build the system from 0→1\.

The Opportunity

:

Be one of the first senior technical hires, working directly with an experienced technical founder to architect a

high-scale, enterprise-grade system

from scratch.

This is a role for someone who wants to:

• Design systems that will underpin

core operational infrastructure for modern companies

• Build at the intersection of

distributed systems, data integrity, and AI-native workflows

• Define the architecture for a platform that must be

secure, auditable, highly configurable, and globally scalable

• Operate as a

hands-on architect

, not a distant reviewer

Key challenges include:

• Designing

transactional, strongly consistent systems

with complex domain models (e.g. effective dating, auditability)

• Building

configurable enterprise-grade security models

(RBAC, delegated authority, fine-grained access)

• Architecting for

high throughput \+ low latency

in workflow-heavy environments

• Creating

self-healing, observable systems

that can operate with minimal human intervention

• Defining

guardrails for AI-assisted development and execution

• Designing APIs and extensibility layers that are

open by design

Experience Requirements:

• Has

built and scaled large, complex backend systems

(not just maintained them)

• Is deeply fluent in:
• Distributed systems design
• Data consistency \& transactional integrity
• Failure modes \& resilience engineering
• Security \& privacy in enterprise systems
• Can think in

multi-year architectural horizons

, not just sprint cycles

• Is still

hands-on and enjoys building

• Can operate as a

technical peer to an experienced CTO

• Saw a system evolve

through scale

, not just after it stabilised

• Have experience in

high-scale infrastructure or enterprise platforms

• Understand the tradeoffs of

configurability vs. complexity

in enterprise products

Why This Role Is Different

• You are not inheriting legacy - you are

defining the system

• You will help build a product in a category with

deep structural pain and no clear winner

• The company is addressing not just software, but the

broader implementation and services burden

around enterprise systems

• You’ll work with founders who have

built and scaled globally-used platforms

• Validated before build
• multiple design partners already committed, with clear signals \& high anticipation to adopt early

This is the

formative build phase

• the decisions made here will define the system for years.
