Описание: Context Labs is seeking a Senior Backend Engineer to help drive forward our product initiatives with our data management platform and analytics spaces. Working as a leader within the development team, the engineer will lead many aspects of developing our “big data” systems, APIs, and related product capabilities; as well as provide thought leadership, upskilling of less senior engineers, and taking part in defining strategic linkages across the company’s products. This role will report to the CTO.

Задачи:

• Serve as a technical authority, providing engineering leadership and architectural guidance.
• Design, develop, and maintain data systems and services for the Immutably™ Platform, ensuring scalable, performant, and maintainable solutions.
• Translate business requirements into technical designs, estimates, and development tasks in collaboration with Product and Engineering.
• Lead technical projects using appropriate programming languages, including Java, Scala, and Python.
• Establish engineering best practices through high-quality code, architecture, documentation, and code reviews.
• Collaborate within an Agile development environment to deliver high-quality software.
• Coach and mentor engineers through technical and methodological challenges.
• Coordinate engineering efforts across distributed teams and multiple time zones.
• Anything else as may reasonably be required by the company.

Требования:

• 10+ years of experience developing large-scale or “big data” systems, with strong knowledge of modern application architectures.
• Expertise with modern data processing technologies such as Spark, Flink, and Arrow, including large-scale query processing.
• Experience with workflow orchestration and scheduling platforms such as Dolphin, Dagster, and Airflow.
• Strong programming experience with JVM languages and Python, including Java frameworks such as Spring.
• Proficiency in API development and integration, including RESTful APIs, GraphQL, and gRPC.
• Experience developing data lakes/data fabrics and working with platforms such as Databricks.
• Proficiency with Docker, Kubernetes, microservices, and relational databases such as MySQL and PostgreSQL.
• Experience with digital asset creation/registration, unit and functional testing, and source code management.
• Strong communication skills with the ability to work independently and take ownership of technical initiatives.

Будет плюсом:

• Experience with functional programming;
• Experience leveraging AI tools – not only building & working with them;
• Tools such as Github Copilot, Cursor AI, Claude Code, Bolt, Open AI Codex, etc. across all disciplines;
• Experience with languages other than Java;
• Experience with frameworks other than Spring (Quarkus/Helidon/etc);
• Experience leading technical talks on topics relating to microservice based systems and processes;
• Experience with NoSQL/NewSQL databases;
• Experience working with the Delta Sharing, Iceberg ReST and other such protocols;
• A bachelor’s degree in computer science or related field
