Senior Software Engineer

About the job
BE is Vietnam's home-grown ride-hailing and super-app, serving millions of riders and drivers every day. We're looking for a Staff Software Engineer to own the architecture of the systems at the core of our marketplace - and to set the technical bar for how we build them.
This is a deeply hands-on role with broad technical leadership scope. You'll define long-term technical direction across squads, make the hard architectural calls, and stay hands-on in the code - that's a must here, not a nice-to-have.
Our tech stack
Hundreds of Golang microservices in a domain-oriented, event-driven architecture, running on GCP, GKE, and Istio with autoscaling, resiliency, a chaos-engineering mindset, and full end-to-end observability.
Mobile on Flutter (component-based, composable). Web on TypeScript, React, [protected info], Tailwind, with an in-house composable design system.
A real DevOps culture: you design, build, and operate your own services, with SRE and Platform support when you need it.
Open-source lovers and contributors - our tooling is built in-house on top of the best of open source.
The platform you'll architect
You'll own the architecture of the systems at the core of the BE marketplace - dispatch, dynamic pricing and surge, the promotion and incentive engine, and the experimentation / A/B platform. These are among the highest-leverage, hardest real-time problems in the company. If these are the problems you want to spend the next few years on, this is the seat.
Your impact
You work with engineering leadership and other staff engineers to define the long-term technical vision for this domain together, and align the squads around durable, business-driven solutions. You own the architecture and technical strategy, and you bring deep domain expertise and real business sense to shape roadmap priorities and investment decisions across teams.
You advise technical leaders on technical strategy for the org, balancing engineering and business priorities to land on the right long-term bets.
What you'll do
Set a high technical bar across the group through deep technical insight, architecture and design reviews, and the standards you hold for code quality and system design.
Review and evolve the dispatch, pricing, promotion, and experimentation systems - making pragmatic, high-impact improvements to availability, performance, and security, rather than rebuilding for its own sake.
Work across Product, Design, and Engineering to solve BE's hardest technical challenges for our riders and drivers.
Drive quality, operational readiness, and engineering excellence across squads, and define the governance and review protocols for major technical decisions.
Plan and run load, stress, and chaos testing to validate reliability and scalability before our users find the limits for us.
Partner with Product to ship features with a data-driven approach, and measure impact through our A/B and experimentation platform.
Requirement
5+ years in software engineering, with a track record of driving technical direction that spans multiple teams and/or services.
Proven experience building and scaling complex, high-impact, high-availability systems in production.
Deep system design skill, especially for distributed, real-time, and high-throughput systems.
Strong command of system performance and scaling, with solid knowledge of MySQL or PostgreSQL. Experience with NoSQL stores such as Cassandra or Elasticsearch is a strong plus.
Experience with chaos engineering is a strong plus.
You write Go, or you're a strong backend engineer eager to - most of our stack is Golang, and we're happy to talk to strong candidates with Java, [protected info], or any similar languages.
You engage directly in the code when it accelerates a critical outcome, and you hold a high standard for quality, design, and architectural decisions across the group.
You communicate clearly, collaborate well while owning your decisions independently, and you're genuinely driven to make systems better.
