At Spartan, we don’t act like vendors.

Together, we help launch MVPs in 30 days and scale systems that power billions of requests. This isn't a batch-and-dashboards seat three layers from the client. You'll be in the founder's Slack. Your pipelines run in production. You'll own the data platform behind real-time operations, analytics, and AI, from ingestion all the way to serving. Data is the core of the job. Backend and infra come with it, because owning the path to production means you deploy your own work and build the services that hand data to the product. You don't need to arrive as an expert in all three. You do need to be willing to learn the other two. 70% of our portfolio is LLM-powered, and every one of those features runs on data someone had to make trustworthy first. That's your work. Cursor, Claude, and Codex are default tools here, not experiments. You'll use AI every day, and you'll be expected to use it well. Who Thrives at Spartan Not every environment fits everyone, so here's an honest picture of the teammates we're looking to build with. You'll thrive here if: You do what it takes to move things forward. A schema redesign today, a backfill script and a founder demo tomorrow. You take on the hardest part of a project and see it through to production. You chase a wrong number until you find where it broke. Silent bad data bothers you more than a loud outage. You'd rather own a problem than simply complete a ticket. You adapt quickly, take responsibility, and care about the impact of what you build. Some weeks will stretch you. That's part of building products in a fast-moving startup environment. But you'll never carry it alone. Whether it's a critical client release or a tricky production issue, your teammates have your back. We push each other because we care about how far each of us can go. We win together. We lose together. Nobody gets left behind. One last thing. We're not just filling seats. We're looking for teammates for the challenges ahead. If you read all this and something in you said yes, trust that feeling and apply. We respect people who back themselves. Every Spartan here started with that same yes. What You'll Do Depending on the project and opportunity, your responsibilities may include: Build data ingestion pipelines for operational, telemetry, and business data, including ETL/ELT, incremental loads, Change Data Capture (CDC), and backfills that don't take production systems down. Design and model data based on how it will be consumed, from upstream event schemas to downstream star schemas, dimensional models, and analytical data marts. Build real-time streaming pipelines with windowed aggregations, stream joins, and robust handling of late, duplicate, and out-of-order events. Own data infrastructure end to end , covering ingestion, processing, storage, transformation, and serving. Ensure data quality and reliability through data contracts, schema evolution, lineage, monitoring, and alerts that detect issues before they impact business decisions. Build the data layer behind AI features , including feature pipelines, embeddings, vector stores, RAG source data, and evaluation datasets. Develop data-serving capabilities , including APIs and services that expose metrics, aggregates, and feature data to product teams. Ship with a proven engineering process , including async standups, PRDs/RFCs, code reviews, automation, and an AI-native workflow using Cursor, Claude, and Codex. Collaborate directly with US startup founders and product leaders , contributing technical insights that shape what gets measured, built, and delivered. Work across engineering disciplines when projects require it. Data Engineering remains your core, but you'll also contribute to backend services, infrastructure, and AI integration. Help shape Spartan's engineering culture , building with ownership, speed, and the mindset of a product engineer rather than a traditional contractor. What We're Looking For We value strong Data Engineering fundamentals, production experience, and the ability to take ownership of systems beyond individual pipelines. Fluent English: Able to communicate confidently with US startup founders, product leaders, and international engineering teams. 3+ years of professional Data Engineering experience , building and operating production data pipelines, including ingestion, ETL/ELT, incremental loads, backfills, and failure recovery. Strong data modeling skills: Experience with normalized schemas for OLTP and dimensional modeling for analytics, including star schemas, fact and dimension tables, slowly changing dimensions, and understanding when denormalization is appropriate. Strong SQL skills: Able to analyze query execution plans, identify performance bottlenecks, and optimize complex queries. Production orchestration experience: Hands-on experience with Airflow, Dagster, Prefect, or similar tools, including scheduling, dependency management, retries, and idempotent reruns. Strong programming skills: Proficiency in Python, Java, Kotlin, or similar languages, with the ability to write tested, maintainable, and reviewable production code. Production streaming experience: Familiarity with Kafka, Pulsar, AWS Kinesis, or similar technologies, including consumer lag, event replays, duplicate events, and delivery guarantees. Cloud and infrastructure experience: Comfortable deploying and debugging data pipelines on AWS, with working knowledge of Infrastructure as Code (IaC), Terraform, and/or Kubernetes. Strong CS fundamentals: Understanding of distributed systems, partitioning, scalability, and the challenges that arise when data grows beyond a single machine. AI-native mindset: Comfortable using AI tools to improve development workflows, critically reviewing generated code, identifying errors, and knowing when not to rely on AI. Builder's mindset: You don't just move data. You build reliable platforms that make data accessible, trustworthy, and useful. Nice to Have Experience in one or more of the following areas will be a plus: Stream processing: Hands-on production experience with Flink, Spark, or Kafka Streams. Warehouse and lakehouse technologies: Experience with dbt, Iceberg, Delta Lake, or real-time OLAP stores such as ClickHouse or Druid. Durable execution: Experience with Temporal or similar technologies for managing long-running workflows. IoT and telemetry: Experience handling high-volume ingestion, late and out-of-order events, and large device fleets. ML and LLM infrastructure: Experience with feature stores, vector databases, and training or evaluation data pipelines. Data platform development: Experience building an internal data platform from scratch. Domain knowledge: Experience in rideshare, logistics, mobility, transportation, or other data-intensive industries. Tech We Use Every project brings a different technology stack, giving you opportunities to work across a broad range of modern data technologies. Our technology choices are driven by engineers through an internal Tech Radar , not simply handed down from a slide deck. Languages: Kotlin, Java, Python, SQL Streaming: Kafka, Pulsar, AWS Kinesis, SQS Processing: Flink, Spark Orchestration: Airflow, Temporal (durable execution) Storage: PostgreSQL, Aurora, Redis, S3 Warehouse & Analytics: Redshift, BigQuery, ClickHouse Data Serving: REST APIs, event-driven architecture Vector Search: pgvector, Pinecone, Qdrant, Weaviate Cloud & Infrastructure: AWS (EKS, S3, RDS), Kubernetes, Docker, Terraform, CI/CD Observability: DataDog, Prometheus, Grafana, ELK Stack AI Tooling: Cursor, Claude, Codex, Gemini Why You Will Love Working Here 100% salary during probation Competitive compensation packages Unlimited PTO + VN public holidays Hybrid working model & flexible working hours MacBook provided Premium healthcare insurance & annual health check Social insurance in accordance with Labor Law License fee support Sports clubs for every taste: football, badminton, billiards, pickleball & Sports participation cost sponsorship PS5 and Nintendo at the office Annual company trip + monthly team parties Work Location HCM: 2nd Floor XL Building, 167 Tran Nao, An Khanh Ward Da Nang: 2nd Floor, 458 Nguyen Huu Tho, Cam Le Ward

Build like a founder. Ship like Spartan. Our clients are startups in a race: an MVP in 30 days, real traffic the day after launch. We’re looking for a DevOps Engineer to keep them fast, up, and cheap to run. We don’t act like vendors. We embed. Our teams sit inside startups backed by YC, Pear VC, BlingCap, a16z, and Techstars, working beside founders and engineers from Stanford, MIT, Yale, Google, Amazon, and Uber. Together we ship those MVPs and scale the systems behind them to millions of users and billions of requests. This isn’t a back-office ops seat three layers from the client. You’ll be in the founder’s Slack. Your infrastructure runs their launch. When their product survives its first traffic spike, that’s your work holding it up. 70% of our portfolio is LLM-powered. That means real GPU workloads, real traffic spikes, and real cloud bills. You’ll design the infrastructure behind it. Cursor, Claude, and Codex are default tools here, and you’ll use them to automate the boring parts. Who Thrives at Spartan Not every environment fits everyone, so here’s an honest picture of the teammate we’re looking for. You’ll thrive here if: You do whatever it takes to win. Terraform today, debugging someone’s Node service tomorrow. You own an incident until it’s resolved, whether it started in your area or not. You treat cost like a feature. You can tell a founder why their bill dropped 40%. You automate the boring parts without being asked. Some weeks will stretch you. That’s the job. But you’ll never carry it alone. A critical incident or a high-stakes migration? You won’t be the only one on it. We push each other hard because we care how far each of us can go. We win together. We lose together.

We respect people who back themselves. Every Spartan here started with that same yes. What You’ll Do Design and run multi-cluster, multi-cloud Kubernetes environments across AWS EKS, GCP GKE, and Azure AKS: highly available, disaster-resilient, auto-scaling. Build GitOps-driven CI/CD pipelines with ArgoCD or FluxCD. Tune performance, reliability, and cost. Every dollar saved is margin for the startup we serve. Run AI infrastructure: GPU workloads, model serving, vector databases, and the inference bills that come with them. Automate ops with AI: runbooks, incident summaries, IaC generation with Cursor and Claude. Secure workloads: RBAC, Network Policies, OPA/Gatekeeper, vulnerability scanning. Work with dev teams on containerization and app modernization. Mentor engineers on Kubernetes and infrastructure practices. Turn what you build into reusable accelerators: CI/CD templates, starter kits, monitoring setups that cut project startup time across clients. What We’re Looking For Fluent English. You’ll talk directly with US startup founders. 3-6 years in DevOps, SRE, or cloud infrastructure, with Kubernetes in production. Strong Infrastructure as Code: Terraform, Helm, Ansible. Deep knowledge of Docker/OCI runtimes, Linux, networking, and troubleshooting. Hands-on with monitoring stacks: DataDog, Prometheus, Grafana, ELK, Jaeger. Solid grasp of Kubernetes internals. You use AI tools like a pro: you review what they write, catch their mistakes, and know when not to use them. A builder’s mindset. You don’t just run infra, you solve problems like an owner. Nice to Have You’ve run LLM serving in production: vLLM, GPU scheduling, or managed inference endpoints. Backend engineering experience. CKA, CKAD, or CKS certifications. Service mesh: Istio, Linkerd, Consul. Open-source contributions to Kubernetes or CNCF projects. Cloud cost optimization wins you can put numbers on. Tech We Use Every project brings a different stack, so in a year here you’ll touch more of this list than most engineers do in five. Two rules hold everywhere: everything as code, no click-ops. And what we adopt is decided by our engineers through an internal Tech Radar, not handed down from a slide deck.
