Our Team Members: We're a dynamic team of 400+ globally distributed members who thrive working from our favorite places around the world, with teammates spanning the USA, Canada, Japan, Hungary, Nigeria, Brazil, the UK, and beyond! We're searching for passionate individuals eager to contribute to Alpaca's rapid growth. If you align with our core values—Stay Curious, Have Empathy, and Be Accountable—and are ready to make a significant impact, we encourage you to apply. Your Role As a Senior Software Engineer on the Platform team, you will build and own the frameworks, tooling, and CI/CD infrastructure that let Alpaca’s engineers ship new features quickly and reliably. This is a software engineering role at its core: you will spend most of your time writing Go, designing automated test frameworks, and digging into application code and Kubernetes when needed. Just as importantly, you will help redefine how we use AI to raise the bar on quality - leveraging LLMs and AI-driven tooling to generate tests, catch regressions before they ship, and turn every incident into durable, automated coverage. We are looking for engineers who treat quality as an engineering discipline and see AI as a force multiplier for it - people who build the systems that make testing fast, reliable, and effortless for the teams that depend on them. Things You Get To Do Design and build automated test frameworks across our REST and gRPC API surface. Leverage AI and LLM-based tooling to accelerate test generation, harden regression coverage, and turn production incidents into automated tests - embedding these practices into the frameworks the whole engineering org relies on. Build and maintain CI/CD pipelines - we use a mix of GitHub Actions and Google Cloud Build. Design and execute load, stress, and scalability tests to ensure our platform can handle growing demand. Introduce chaos engineering practices - designing fault-injection and resilience experiments that surface failure modes before our customers do. Standardize tooling and infrastructure to improve the day-to-day developer experience. Partner with other teams to raise test coverage, reliability, and speed across services. Dig into application code to root-cause failures and drive fixes to completion. Mentor and guide product engineers, fostering a culture of quality and continuous improvement. Who You Are (Must-Haves) You have 5+ years of experience as a software engineer building and maintaining production systems. You have written code in strongly typed languages and have at least 1 year of experience with Go. You are fluent with AI-assisted engineering - you actively use LLM-based tools in your workflow and have a clear point of view on where they elevate quality (and where they don’t). You have built and maintained CI pipelines before - ideally with GitHub Actions or Google Cloud Build. You have designed and built automated test frameworks, and you understand the challenges microservices pose for reliable integration and end-to-end testing. You are familiar with Kubernetes beyond the basics - you can write a Helm chart for a new service with relative ease, you understand best practices around security, and you have prior job experience or certifications to prove this. You have worked at a startup before - you understand that things don’t always go according to plan, that there is significant technical debt, that some tasks just need to be done, and that sometimes there are no processes or documentation to guide your hand. You are not afraid of taking a task from start to finish - gathering requirements, figuring out and implementing the best technical solution, then deploying and monitoring the results. Who You Might Be (Bonus Points) You have used AI/LLM tooling to build QA automation - test generation, flaky-test triage, or incident-to-regression pipelines - and can speak to what worked and what didn’t. You have written code in Python or TypeScript, and can build efficient Dockerfiles and secure container images. You have implemented load tests with k6 (REST) and ghz (gRPC) and have experience analyzing pprof/trace output. You have done IaC deployments with Argo CD or Terraform, or have used Google Cloud Platform and Google Kubernetes Engine before. You are familiar with Tilt and have written a Kubernetes Operator before. You have practiced chaos engineering - running fault-injection or resilience experiments with tools like Chaos Mesh, LitmusChaos, or Gremlin. You are familiar with testing event-driven systems using Kafka (or even better, Redpanda).

Location: Portugal; Albania; Georgia; Greece; Bulgaria; Kosovo; Bosnia and Herzegovina; Armenia; Italy; Spain; Malta; Romania; Ireland; Croatia; Serbia; Montenegro Workplace: Remote ABOUT BLOCK LABS Block Labs is a premier technology studio operating at the bleeding edge of Web3, Artificial Intelligence, and iGaming. We don't just ship features; we engineer high-scale, production-grade platforms that power the next generation of digital products. We are a collective of senior engineers, product strategists, and builders who refuse to compromise on architecture. Whether we are designing autonomous multi-agent AI systems, building decentralized financial infrastructure, or architecting high-frequency iGaming platforms, our standard is excellence. We move fast, but we build for the long term. If you are looking to work alongside a team that values deep technical expertise, thoughtful system design, and product ownership, Block Labs is where you belong. THE ROLE Data & Intelligence now sits at the centre of several products we are developing, and we need a platform that is both dependable and capable of supporting more advanced intelligence over time. This role reflects that shift. We are designing a new data platform that will act as the backbone for everything from real time decisioning to predictive modelling. As a Data Platform Engineer in the Data Team, you will own the end-to-end real-time pipeline, serving data across a unified analytical warehouse and feature-serving layer. You are not building dashboards. You are engineering the commercial nervous system of a multi-tenant platform designed to scale from one operator to 10x with marginal infrastructure cost. KEY RESPONSIBILITIES: - Design, build, and maintain scalable data pipelines using AWS Glue (PySpark), or equivalent orchestration and transformation tools. - Engineer and optimise the ClickHouse warehouse for sub-second query performance across all back-offices. - Implement data contracts between back-office and the platform. Onboarding a new operator is a config change, not new tables, topics, or feature views. - Build the feature-serving layer providing pre-computed features to AI agents at millisecond latency. - Integrate with third-party databases, back-office APIs, and external systems (CRM, affiliates, acquisition platforms). - Establish monitoring, alerting, and maintenance procedures including pipeline health checks, freshness monitoring, anomaly detection, and data contract SLA enforcement. - Own CI/CD and infrastructure-as-code for data workloads. - Collaborate with data scientists, agent engineers, BI developers, and infrastructure teams to translate data requirements into reliable, production-grade pipelines. ABOUT YOU: - 3+ years building and operating production data pipelines at scale, with hands-on experience across both streaming and batch paradigms. - Expertise in Apache Kafka (or Amazon MSK): topic design, consumer group management, offset handling, schema registry operations, and production troubleshooting of lag, rebalancing, and throughput issues. - Strong SQL and warehouse engineering skills: experience with columnar analytical databases (ClickHouse strongly preferred, or similar: Druid, BigQuery, Redshift). - PySpark / Spark Streaming proficiency: writing transformation jobs that normalise, enrich, and enforce business rules on event streams. Experience with AWS Glue, Apache Airflow, or Apache NiFi is a strong plus. - Data modelling discipline: ability to design normalised, multi-tenant schemas where tenant isolation is a filter, not a fork. Experience with data contracts and schema governance. - CI/CD and infrastructure-as-code experience: automated testing of data pipelines, version-controlled deployments (CloudFormation, Terraform, or CDK), and familiarity with containerised workloads (ECS Fargate or Kubernetes). - Data quality and observability mindset: experience implementing pipeline health monitoring, automated data validation (Great Expectations or equivalent), freshness checks, and anomaly detection. NICE TO HAVE - Experience in iGaming, online casino, poker, or sportsbook platforms. - Exposure to blockchain or crypto-native transaction flows, including on-chain event ingestion, token-denominated accounting, or stablecoin settlement. - Comfortable operating in an AWS-native environment (MSK, Glue, S3, DynamoDB, ECS, IAM). You understand serverless tradeoffs and can size infrastructure for cost efficiency. - Feature store experience (SageMaker, Feast, or Tecton) building offline/online feature pipelines that serve ML models at inference time. - Prior work in regulated industries (financial services, gambling, fintech) where data lineage, auditability, and compliance are non-negotiable. - Experience migrating legacy query engines (Athena, Trino, Presto) to modern analytical warehouses with reconciliation frameworks to validate correctness. HOW WE WORK - Fully remote with asynchronous-first communication. EU time zone overlap is preferred. - Small, high-autonomy team within the Data function. You report to the Head of Data and co-ordinate with the AI, BI, and Infrastructure Teams. - Architecture decisions are documented and debated. You will participate in design reviews and own your domain decisions. - We build for multi-tenant scale from day one. Every pipeline, schema, and contract you ship must absorb a new operator without engineering effort. - On-call rotation will be established in the run phase. During the build phase, the focus is velocity with quality. No firefighting legacy systems. What kind of culture can I expect? Mature, mission-driven, and low-ego. We value clarity over noise, outcomes over theatrics, and pace without chaos. If you’re one of the smartest minds in your craft and want to build with other experts, you’ll feel at home here.

Задачи: — Разработка и поддержка серверных приложений и RESTful API на Kotlin (Ktor или Spring Boot). — Проектирование микросервисной архитектуры с паттернами межсервисного взаимодействия. — Проектирование и оптимизация схем баз данных PostgreSQL/MongoDB, реализация кэширования (Redis). — Интеграция брокеров сообщений (Kafka, RabbitMQ) для асинхронной и событийно-ориентированной обработки. — Реализация аутентификации и авторизации (JWT, OAuth2), написание чистого и документированного кода. — Контейнеризация приложений с Docker, оркестрация с Kubernetes, настройка CI/CD. — Написание unit и интеграционных тестов (JUnit, MockK), оптимизация производительности. — Взаимодействие с мобильными и фронтенд-командами по API контрактам, участие в код-ревью. Требования: — Опыт коммерческой backend-разработки на Kotlin от 3 лет. — Глубокие знания Kotlin и практический опыт с Ktor или Spring Boot. — Понимание REST API и опыт работы с PostgreSQL/MySQL и ORM. — Практический опыт с Coroutines, Flow, брокерами сообщений (Kafka, RabbitMQ, Redis). — Знание микросервисов, стратегий кэширования, контейнеризации (Docker, Kubernetes). — Опыт работы с Git, CI/CD инструментами, тестовыми фреймворками (JUnit, MockK, Kotest). — Базовые знания облачных платформ (AWS, GCP, Azure) и лучших практик безопасности. — Сильные навыки решения проблем и умение работать в распределенной команде. — Английский язык на уровне B2 и выше (письменно и устно). Будет плюсом: — Опыт с GraphQL, gRPC, event sourcing/CQRS. — Знания Elasticsearch, serverless, распределенного трейсинга. — Опыт с другими JVM-языками (Java, Scala), потоковой обработкой данных (Kafka Streams, Flink). — Знакомство с поисковыми системами, MLOps, блокчейн-бэкендом. — Вклад в open-source проекты на Kotlin или backend.
