about the role

walmart's me@walmart is the mobile experience that puts the power of walmart in every associate's hands — 2m+ associates globally, across every store, dc, and market. As the principal engineer for me@walmart global platform (international), you'll be the senior technical anchor responsible for how our international markets (mexico, canada, chile, central america) consume, adapt, and extend the me@walmart global platform.

this isn't a role that ships features. This is the role that ensures features can be shipped — on time, at scale, across languages, currencies, and regulatory realities — without every market team reinventing the wheel. You'll own the technical direction for how me@walmart lands in every international market, feed our market-specific requirements back into the global platform, and coach the staff engineers who execute the day-to-day delivery

what you'll do

own the technical direction for me@walmart general platform (international)

- author and evolve the me@walmart international platform strategy — a multi-quarter technical roadmap covering integration surface, extension points, multi-market rollout patterns, and the standard operating model for market teams to consume the global platform.
- represent international tech in us me@walmart global platform forums — ensuring our market realities (lgpd, lfpdppp, local payment methods, language, currency, offline-first store use cases) are reflected upstream, not bolted on downstream.
- chair the international me@walmart design review (bi-weekly, cross-market) and set the adr / rfc standard the org will operate by.

drive cross-market platform adoption and parity

- define and publish an international parity matrix — the objective view of how each market compares to the us me@walmart baseline (features shipped, platform versions consumed, technical debt outstanding, gaps prioritized).




- partner with each market's engineering manager and staff engineers on market-specific rollout plans for global platform capabilities.
- own the mini-app / plug-in extension model for international, including the table.loop registry governance, semver policy, and deprecation lifecycle.

elevate the engineering practice around you

- coach and calibrate staff-tier engineers across mx (firebase intl, magic frameworks, polaris wfm interfaces, store systems). Named coaching relationships, not drive-by mentorship.
- author public engineering artifacts — adrs, rfcs, internal blog posts, tech talks — that document how we make platform decisions at international tech.
- serve as calibration and promotion signal for sr staff and staff swe promo cycles.

own international me@walmart reliability & operational excellence

- be the named escalation owner for me@walmart platform-integration incidents affecting multiple markets.
- publish a quarterly root-cause taxonomy and drive structural fixes that remove classes of incidents, not just individual firefights.
- reduce me@walmart international p1 / p2 incidents attributable to the integration surface by 30% year over year.

what you'll bring required

- 9+ years total software engineering experience, with at least 3 years at staff, principal, or distinguished level.
- built or owned a mobile platform sdk consumed by 5+ downstream app teams (e.g. Uber base, airbnb dls, meta react native infra, grab kit, in-house super-app platforms.




- deep hands-on with both native mobile (kotlin / jetpack compose, swift / swiftui) and cross-platform (react native or flutter). This role reads code across all three.
- led a multi-market or multi-tenant rollout of a global product to at least 3 markets / tenants with different regulatory, language, or payment realities.
- portfolio of authored engineering artifacts — adrs, rfcs, blog posts, conference talks, patents, or open-source maintainership. If you can't produce at least one written design doc from the last 24 months, this role isn't a fit. Track record of coaching staff engineers to promotion — ideally named on 2+ promo packets as an endorser or coaching sponsor.
- written and verbal fluency in english; conversational spanish is a strong plus (audience in mx is bilingual.
- comfort with mx central hours + occasional early-morning overlap with us bentonville.

strongly preferred

- prior work in retail, fintech, or super-app environments where the mobile app is the product (not a companion experience).
- experience with mini-app / plug-in architectures (wechat, alipay, line, grab, or in house equivalents.
- hands-on with firebase (remote config, a/b, crashlytics, app distribution, fcm) at scale.
- comfort with observability & performance engineering (datadog rum / mobile sdk, custom telemetry, distributed tracing across mobile → bff → service, perf budgets.
- familiarity with walmart's stack — wcnp / concord / kitt, dcs-w (data credential service), gtp-bom compliance, kafka on walmart platform, magic framework, gec github + sonar gates. (if not, you'll ramp fast — but familiarity accelerates year 1 impact.
- public engineering identity: conference speaking (droidcon, rn conf, wwdc labs), oss maintainership, or a technical blog with a real readership.
