Client Solution Architect

About OneByZero

OneByZero is a Frontier Systems Integrator building agentic AI systems for leading banks, telecommunications companies, insurers, and retailers across Asia Pacific. We work on high-impact problems for institutions operating the financial and digital infrastructure of the region.

We operate exclusively on AWS and leverage partnership programmes that provide co-sell reach, funded innovation opportunities, and delivery credibility across multiple markets. We value individuals who are technically strong, commercially aware, collaborative, and focused on delivering measurable business outcomes.

The Role

The Client Solution Architect (CSA) is the technical authority during enterprise pursuits and strategic solution engagements. The CSA leads architecture discussions, shapes technically credible solutions, validates delivery feasibility, and supports commercial teams in structuring scalable and deliverable engagements.

This role operates across OBZ’s core offerings including Agentic Data Modernisation, Agentic Process Transformation, and VM Migration. The role requires strong working knowledge across enterprise data architecture, agentic AI systems, cloud infrastructure, security, governance, and enterprise modernization patterns, with deep expertise in at least one domain area.

The CSA works closely with the Client Solution Partner, Enagement Manager, Principal Architect, delivery teams, and AWS stakeholders to ensure pursuits are technically sound, commercially viable, and operationally deliverable.

This role remains engaged through mobilisation and early delivery phases to ensure the transition into delivery is structured, documented, and operationally aligned. At OBZ, all team members are expected to use AI tools effectively in their daily work. AI assistants and workflow automation tools are expected to improve architecture design, proposal development, estimation, proof-of-concept development, technical analysis, and solution validation activities.

What You Will Do

Lead technical solution design across enterprise pursuits and strategic client engagements.

Conduct architecture workshops and technical discussions with client CTOs, CIOs, CDOs, enterprise architects, AWS architects, engineering leadership, and transformation teams.

Understand business priorities, technical constraints, governance requirements, security expectations, and operational realities across regulated industries including banking, telecommunications, insurance, and other enterprise sectors.

Design scalable, secure, and production-ready enterprise architectures across AI, data, cloud, and modernization initiatives.

Own the technical proposal lifecycle including architecture definition, scope clarification, assumptions, dependencies, non-functional requirements, technical risks, and delivery estimation.

Build and own proof-of-concepts (POCs) independently using AI tools and engineering accelerators. The expectation for this role is hands-on ownership of early solution validation and prototype development without dependency on junior engineering support during pursuit stages.

Define architecture approaches across AWS services, modern cloud platforms, open-source ecosystems, and enterprise technology stacks. This includes AWS-native services as well as technologies such as Databricks, Snowflake, Kubernetes, Apache Iceberg, Spark, dbt, Airflow, vector databases, orchestration frameworks, and enterprise integration platforms where appropriate.

Shape solutions across OBZ platforms including Neo, ETL Migration Crew, agentic orchestration platforms, and enterprise modernization accelerators.

Work with the CSP and FDP to ensure the commercial structure aligns with technical feasibility, delivery assumptions, and operational constraints.

Define security, resilience, governance, compliance, performance, scalability, and operational requirements as core architecture inputs from the beginning of the engagement.

Participate in architecture governance reviews, security reviews, compliance discussions, and technical due diligence sessions with client stakeholders and AWS teams.

Stay involved through mobilisation and early delivery phases to ensure the Principal Architect inherits the engagement with full architectural context, rationale, risks, assumptions, and delivery alignment.

Support expansion opportunities within active accounts alongside the CSP and FDP by shaping follow-on programmes and technical transformation roadmaps.

Build reusable solution assets from every pursuit including reference architectures, sizing models, proposal frameworks, evaluation models, migration approaches, governance templates, and technical accelerators.

Contribute reusable intellectual property and technical standards into OBZ’s broader knowledge base so future pursuits and delivery teams operate from an increasingly stronger foundation.

What We Are Looking For

10+ years of experience in solution architecture, enterprise cloud architecture, AI transformation, or enterprise technology consulting within complex multi-stakeholder environments.

Strong experience leading enterprise technical pursuits end-to-end including architecture definition, solution shaping, estimation, proposal ownership, and technical validation.

Ability to independently conduct initial technical and architectural discussions with enterprise clients, AWS architects, enterprise architecture teams, and senior technology stakeholders.

Strong AI fluency and hands-on experience using AI tools, coding assistants, workflow automation tools, and prototyping platforms as part of day-to-day architecture and solution development activities.

Cross-domain technical understanding across enterprise data architecture, agentic AI systems, cloud modernization, security, infrastructure, and enterprise integration patterns.

Strong expertise across enterprise cloud and modernization services relevant to OBZ offerings. Deep AWS expertise is strongly preferred; however, candidates should also demonstrate strong understanding of broader enterprise cloud, AI, and data technology ecosystems.

Experience across AWS services relevant to AI, data, modernization, governance, and enterprise architecture initiatives.

Strong understanding of enterprise modernization patterns across banking, telecommunications, insurance, and regulated industry environments where governance, security, and architecture decisions are heavily influenced by industry-specific operational and regulatory constraints.

Strong experience leading proof-of-concepts, technical validations, architectural workshops, and enterprise solution discussions.

Strong commercial awareness including pricing models, delivery estimation, operational feasibility, and margin protection considerations.

Strong understanding of agentic AI systems, RAG architectures, orchestration patterns, data platform architectures, and enterprise AI operational challenges.

Strong estimation discipline with the ability to surface assumptions, technical dependencies, governance risks, and operational constraints clearly during pursuit stages.

Strong executive communication capability with the ability to engage credibly with CTOs, CIOs, CDOs, AWS stakeholders, architects, and transformation leadership teams.

Strong documentation and handoff discipline to ensure successful transition from pursuit into delivery execution.

What Sets You Apart

You have led proof-of-concepts or technical validations that materially influenced enterprise transformation decisions or helped win strategic engagements.

You actively use AI tools to improve architecture design, proposal quality, estimation accuracy, technical analysis, and proof-of-concept development.

You have balanced technical quality, delivery feasibility, governance requirements, and commercial considerations within complex enterprise pursuits.

You have contributed reusable architecture patterns, sizing frameworks, migration models, or technical accelerators adopted across multiple engagements.

You combine deep technical expertise with strong executive communication and commercial awareness.

Travel and Location

OBZ clients are based across Southeast Asia, ANZ, and Japan. This role supports regional pursuits and enterprise engagements and may require travel for workshops, architecture sessions, proposal presentations, and mobilisation activities. Relocation support may be considered based on business requirements.

What Success Looks Like

Enterprise clients select OBZ because the proposed architecture is technically credible, operationally deliverable, and commercially aligned.

Solutions transition successfully from pursuit into delivery without significant architectural redesign or delivery instability.

Principal Architect and delivery teams inherit engagements with strong architectural clarity, governance alignment, and operational readiness.

Reusable solution assets, architecture patterns, estimation frameworks, and technical accelerators improve pursuit quality and delivery maturity across the organization.

OBZ’s win rates, technical credibility, and enterprise positioning strengthen through the quality of the solutions designed.

Language

Fluency in spoken and written English is required across all markets. Strong communication skills are essential when engaging with client stakeholders, AWS teams, executives, architects, and cross-market delivery teams.

Local language proficiency is considered an advantage, particularly in Japan, Vietnam, Thailand, and the Philippines.

Certifications

AWS Certified Solutions Architect Professional is required.

AWS Certified AI Practitioner and AWS Certified Machine Learning Specialty or Machine Learning

Engineer Associate certifications are required.

AWS Certified Generative AI Developer, AWS Certified Security Specialty, AWS Certified Data Engineer

Associate, and related modernization or cloud certifications are strongly recommended.

What We Offer

Competitive compensation aligned to market standards. Opportunities to work on enterprise-scale AI transformation programmes across Asia Pacific. Exposure to advanced AI tooling, AWS partnership ecosystems, enterprise modernization initiatives, and strategic regional transformation programmes.

OneByZero is an equal opportunity employer committed to building a diverse and inclusive workplace.

Why OneByZero

The most complex enterprise AI and modernization problems are solved during the pursuit and architecture-definition phase, where technical credibility, governance understanding, and commercial realism must align simultaneously. The Client Solution Architect role operates at the intersection of enterprise architecture, AI transformation, commercial strategy, and delivery readiness across some of the region’s most important enterprise transformation programmes.
