Treasure Data:

At Treasure Data, we’re on a mission to radically simplify how companies use data and AI to create connected customer experiences. Our intelligent customer data platform (CDP) drives revenue growth and operational efficiency across the enterprise to deliver powerful business outcomes.

We are thrilled that Forrester has recognized Treasure Data as a Leader in The Forrester Wave™: Customer Data Platforms For B2C. It's an honor to be acknowledged for our efforts in advancing the CDP industry with cutting-edge AI and real-time capabilities.

Furthermore, Treasure Data employees are enthusiastic, data-driven, and customer-obsessed. We are a team of drivers—self-starters who take initiative, anticipate needs, and proactively jump in to solve problems. Our actions reflect our values of honesty, reliability, openness, and humility.

We are investing heavily in our core platform to support sustained growth in data volume, customer complexity, and reliability expectations.

About the Ingestion Team

The Ingestion team owns the mission-critical systems that serve as the front door to the Treasure Data platform. These systems must handle billions of events per day, absorb bursty and unpredictable traffic, and evolve safely as customer needs and scale grow.

At this level, Ingestion is not just about throughput—it is about long-term platform correctness, cost control, and architectural simplicity at scale.

Your Role

As a Staff Software Engineer, you will operate as a senior technical leader within the Ingestion team and across the platform:

• Lead the design and evolution of large-scale ingestion architectures supporting multi-fold traffic growth

• Own complex, cross-service initiatives that span multiple teams or domains

• Anticipate scaling, reliability, and cost challenges before they impact customers

• Set technical direction for major subsystems and influence broader platform architecture

• Drive improvements in operational excellence, incident response, and system observability

• Partner closely with engineering leadership, product, and customer-facing teams on strategic initiatives

• Serve as a technical mentor and multiplier, elevating the skills and effectiveness of engineers across the organization

• Participate in on-call rotations with a focus on systemic fixes rather than tactical responses

About You

You are a senior backend engineer with a strong track record of owning and evolving production systems at scale. You:

• Have 6+ years of professional software engineering experience

• Have led the design and operation of distributed systems handling high-volume, mission-critical workloads

• Think in terms of system behavior, failure modes, and long-term tradeoffs—not just features

• Are comfortable making and defending architectural decisions with significant business impact

• Communicate complex technical ideas clearly to both technical and non-technical stakeholders

• Are fluent in Kotlin/Java ecosystems and experienced with AWS-based architectures

• Business-level English proficiency

Bonus Points

• Deep experience with large-scale streaming platforms or ingestion pipelines

• Experience driving platform evolution through multiple generations of scale

• Proven ability to reduce infrastructure cost while increasing reliability

• Experience influencing technical direction beyond a single team
