Data Translator Role
How DataTalks.Club guests define the data translator role: translating between business decisions and technical delivery, building trust, prototyping, handing work over, and setting boundaries with adjacent data roles.

The data translator role sits between business decisions and technical data delivery. In Lior Barak’s data translator and data strategy discussion, the role isn’t a reporting layer that forwards requests. It keeps data engineering, data science, and business teams aligned around shared definitions and constraints. It makes outputs trustworthy enough to use in decisions (4:08-7:46).
The role overlaps with data strategy and communication. It also sits near data product adoption because dashboards, forecasts, models, and workflow tools need to change decisions rather than merely exist. Barak frames the translator as a product-minded data advocate. The person asks basic questions and explains uncertainty. They sit with users, prove value through small prototypes, and help move work into owned production systems (4:08-14:20 and 23:54-32:42).
A Bridge With Product Judgment
Barak’s definition starts from language and trust. Business users ask why a number changed, whether a forecast is reliable, and why an “install” or “session” is counted a certain way. Technical teams know the models, SQL jobs, and data-quality limits. They may still miss the exact business workflow. The translator makes both sides legible to each other (4:08-7:46).
The strongest version of the role isn’t purely non-technical. Barak describes his own background as technical enough to read code, write SQL, and write Python. He also understands what’s happening while coming from product management. That combination lets the translator explain technical effort without pretending to be the production engineer who should own every implementation (6:36-7:46).
Marco De Sa’s chief data officer discussion places the same bridge inside senior leadership.
In the CDO role Marco De Sa describes strategy for infrastructure and governance. Data collection, AI, and user value belong in the same scope. He also names a recurring disconnect.
Business leaders have problems to solve, while technical teams can focus on technology instead of the business problem (6:08-10:19). That executive version is wider than Barak’s translator role. It supports the same principle: data work has to be framed from the business outcome back into technical delivery.
Trust Is Part of the Job
For Barak, trust is an operating responsibility, not a soft afterthought. When a job fails or a formula is wrong, the data team should warn users before they act on bad numbers. A small alert says whether the data is safe to use. It prevents a trust loss that can later create repeated rechecking and backlog pressure (7:46-10:48).
Forecasts need the same translation. Barak recommends showing confidence and explaining the data available at prediction time. He also recommends exposing QA checks when a model changes because marketing traffic, input features, or user mix shifted. The deliverable isn’t only the model output. It’s the context that lets non-specialists decide how much to rely on the number (10:48-13:15).
This makes the role close to data product adoption. People use a dashboard, metric, or model when they can find it and trust it at the decision point. Barak’s trust tactics also support data quality and observability because alerts and QA dashboards make reliability visible. Clear ownership keeps that reliability from becoming hidden engineering work.
Discovery Happens Beside the Work
The data translator doesn’t learn the business only through tickets. Barak argues that data engineers, analysts, and data scientists should sit with the teams that use their work. Marketing and finance users reveal how work actually happens. Product, recruiting, and operations users do the same.
In his examples, the useful idea appears when a technical person notices repeated clicks. Manual report downloads or process friction can also turn into an MVP (14:20-20:25).
That discovery style sits near data product management. Both roles start from user problems and business workflows, but their scope differs. A data product manager usually owns roadmap tradeoffs, product lifecycle, and adoption metrics for a data capability. A data translator may discover the mismatch, frame the value, explain constraints, and help the right owner move the work forward (14:20-17:33 and 29:19-32:42).
Thom Ives gives a useful boundary in Practical Data Science and ML. Thom Ives warns data scientists not to pretend to be the company’s domain expert. Instead, they should ask leaders what worries them and map business needs against current data assets. That matrix shows where data can help now or where collection needs to improve (10:51-13:39).
The two guests disagree in emphasis rather than contradicting each other. Barak pushes data people closer to the workflow, while Ives warns them to serve domain experts instead of replacing them.
Prototype, Then Hand Over
Barak’s translator role is prototype-first. When there’s resistance, a hackathon, side project, or one-week trial can show value before the team asks for a larger commitment. He recommends lean delivery by creating the smallest useful version, releasing it, learning whether people use it, and then hardening the system (20:25-26:17).
The data product management page uses similar product logic, but Barak is more explicit about “ugly” first versions. A spreadsheet, rough dashboard, or quick script can prove that the business has a real use case. Once it works, the translator helps create ownership for rewriting, automation, or productionization. The original builder shouldn’t cling to the prototype if another engineer needs to rebuild it (26:17-32:42).
Ives makes the same tradeoff from the data-science side. He recommends fast end-to-end “tracer bullet” delivery and frequent customer feedback before thickening the solution with every desired feature. He also argues that value can appear before a model goes to production. Preparation, visualization, and feature analysis can already inform the business (13:39-19:32).
Boundaries With Adjacent Roles
The data translator isn’t the same as a data analyst. Analysts often own analysis, reporting, and metric interpretation. They may also own stakeholder answers. A translator may do some of that work.
The role is still defined by cross-boundary translation. The translator aligns definitions and explains model or pipeline uncertainty. The translator also finds the workflow problem and makes sure a useful prototype gets a durable owner (4:08-14:20 and 29:19-32:42).
The translator also isn’t the same as a data engineer. Engineers design and operate pipelines, infrastructure, APIs, and production systems. Barak’s handover examples make the boundary explicit. Rough code can prove a point, but someone must take ownership for maintainable implementation and future operation once the use case is clear (26:17-32:42).
Against data product management, the translator is usually less about formal roadmap ownership. The role makes work intelligible enough that the right product, engineering, or business owner can act. Against leadership, the translator doesn’t need executive scope. Marco’s CDO role decomposes data strategy across people, pillars, and long-term goals. Barak’s translator role works closer to daily friction, trust repair, and handover (11:40-23:13, 14:20-32:42).
Communication Without Silos
The role depends on everyday communication. Barak recommends speaking in the listener’s language and showing enough of the technical process to explain why work takes time. He also recommends warning stakeholders early when a blocker changes delivery. Non-technical stakeholders may not read code, but they can understand blockers and dependencies. They can also understand the business consequence of a delay (36:33-40:59).
Remote work changes the tactic, not the principle. Barak suggests joining the business team’s chat channels and noticing relevant triggers. The translator shares work where users already talk and asks for feedback before announcing a release only inside the BI or data team. He’s skeptical of joining every recurring meeting just to observe. The translator should use lightweight proximity to find moments where a conversation matters (40:59-45:06).
Marco’s executive view reinforces the same communication boundary. Senior data leaders need to articulate vision, strategy, and influence across the organization. They also need to hire or empower people who execute better than they can personally execute every tactic (14:24-20:17 and 52:18-59:40). A data translator does that work at a smaller scale through shared language, visible tradeoffs, and credible handoffs between teams.
Examples in the Role
In Barak’s examples, a translator can turn repeated manual bidding clicks into a small tool. Recruiting process data can become a dashboard that helps unblock hiring. Manual report downloads can become automation that gives employees time to make decisions instead of copying files. These examples matter because the discovery came from observing the user’s day, not from reading a generic dashboard request (17:33-23:54).
Other examples are less visible but just as important. Translators send proactive data quality alerts and explain why a forecast changed. They expose confidence and QA checks. They also make sure business users understand when a quick prototype is only a taste of the future system. These are deliverables of the translator role because they protect trust while the technical work moves from experiment to production (7:46-13:15 and 34:52-40:59).
