Data Practice lead

About OneByZero

OneByZero is a Frontier Systems Integrator building agentic AI systems for leading banks, telcos, insurers, and retailers across Asia Pacific. We work on mission-critical problems for organizations operating the region's financial and digital infrastructure. Operating exclusively on AWS, we combine deep technical expertise with strong partnership programs that enable innovation, scale, and delivery excellence. We build with people who are technically serious, outcome-focused, and passionate about solving complex enterprise challenges.

The Role

The Data Practice Lead owns the technical vision, capability building, and presales strategy for OBZ's Data practice — anchoring large-scale opportunities and ensuring what's sold can be delivered.
This is a hands-on leadership role: you'll architect and steer data platforms on AWS, build and scale engineering teams, and be the technical face of the practice in front of clients and senior stakeholders.

What You Will Do

• Practice Leadership – Define the roadmap for OBZ's Data practice, tracking market trends
and emerging technologies.

• Platform & Architecture
– Architect and oversee data engineering platforms
— ingestion, warehousing, and lakehouse — on AWS.

• Team Building – Hire, mentor, and scale a high-performing data engineering team;
build a culture of quality, automation, and ownership.

• Innovation & Offerings – Build differentiated solution offerings, use cases,
and capability decks that position OBZ as a credible data engineering player.

• Asset Creation – Build reusable frameworks, accelerators, and an internal knowledge
base from past projects.

• Solution Architecture – Partner with presales/account leads on medium-to-large
opportunities; turn data strategy into proposal narratives.

• Bid Strategy – Own end-to-end proposal development for data-centric RFIs/RFPs.

• Executive Facilitation – Lead client-facing strategy sessions covering solution, delivery
approach, and commercial terms.

• Cross-Functional Alignment – Be the bridge between Sales and Delivery — make
sure sold scope is deliverable.

• Profitability Management – Own bid pricing and profitability models for Data practice deals.

Requirements

What We Are
Looking For

• 12+ years in Data Engineering
or Analytics, including experience leading a practice, COE, or large
engineering team (20+).

• Hands-on depth on AWS and
modern data engineering stacks — Spark, Databricks, Kafka, and equivalent
ingestion/orchestration tools.

• Strong grounding in DevSecOps
practices and enterprise data governance (MDM, data quality, cataloging).

• Proven presales experience —
RFP/RFI response, solutioning, and CxO-level client engagement.

• Advanced Google Workspace,
PowerPoint, and Excel.
​

What Sets
You Apart

• Deep, hands-on AWS experience
across large-scale data platforms.

• A track record of building a
data practice or COE from the ground up.

• Experience across regulated,
enterprise domains such as BFSI, retail, telecom, or insurance.

Travel and
Location

OBZ clients are
based across Southeast Asia and ANZ. Travel and onsite engagement requirements
may vary depending on project and deal needs.

What
Success Looks Like

• The Data practice has a clear
roadmap, reusable assets, and a growing bench of strong engineers.

• Presales cycles you own convert
into signed, deliverable engagements.

• Sales and Delivery see you as
the trusted bridge — few surprises between what's sold and what's built.

• Bid pricing and profitability
stay healthy across the deals you shape.

Language

Fluency in
spoken and written English is required. Strong communication skills are
important for engaging C-level stakeholders, presales teams, and delivery
leadership across markets.

### Benefits
What We Offer

Competitive compensation benchmarked to market. The opportunity to work on AI transformation programmes that matter to the institutions millions of people in Asia Pacific depend on. A team that spans 10 markets, brings together some of the most experienced AI, data, and enterprise technology practitioners in the region, and moves fast without losing quality. Access to the AWS partnership programmes and frontier AI tooling that most firms in this region do not have. A firm that is building something genuinely new, with a leadership team that has scaled and delivered before.
OneByZero is an equal opportunity employer. We are committed to building a diverse and inclusive team and welcome applications from candidates of all backgrounds.

Why OneByZero

Agentic AI in regulated enterprise is the hardest version of this problem. The clients are the institutions that run the financial infrastructure of Asia Pacific. The constraints are real. The stakes are high.
OBZ is one of the few firms in the region doing this work at production scale in regulated industries, with an AWS partnership that puts you at the frontier of what is deployable. You will build systems that matter, work in squads small enough that your contribution is visible, and use AI coworkers as a genuine force multiplier.
If you are at the start of your career and want to be shaped by the hardest agentic engineering problems in the region, this is where that happens. If you are experienced and want to work on problems that are still genuinely unsolved, this is also where that happens.
