We are hiring an experienced Apache Flink Engineer (contract) to build and help operationalise the stream-processing components of a near real-time personalisation and recommender capability on AWS.
Role overview
You will bring deep hands‑on expertise in production Flink on AWS, working closely with a senior FT engineer and AWS stakeholders. A key part of the role is knowledge transfer through pairing, reviews and clear documentation so the capability can be supported and extended by FT.
Responsibilities
- Design and implement stateful stream-processing jobs in Apache Flink (primarily Java), to process user interaction events and produce near real‑time outputs for downstream services.
- Integrate Flink with Kafka/AWS MSK, S3 and the chosen online store (MongoDB/MongoDB Atlas).
- Own streaming non‑functional requirements: correctness, fault tolerance, checkpointing/recovery, backpressure handling, and performance tuning.
- Define and implement production readiness: observability (metrics/logs/tracing), alerting, dashboards and runbooks.
- Support CI/CD and infrastructure‑as‑code practices to deploy and operate Flink workloads safely in AWS.
- Enable the team via knowledge transfer (pairing, design/code reviews, documentation and handover).
Requirements
Skills and experience
Essential
- Strong experience building and operating production Apache Flink applications (event‑time concepts, windows/watermarks, state, checkpointing and fault tolerance).
- Hands‑on AWS experience operating streaming/data workloads (IAM, networking/VPC basics, deployment, observability and incident troubleshooting).
- Experience integrating Flink with Kafka (including AWS MSK) and cloud services/storage (e.g., S3).
- Highly proficient in Java and Python (production experience required).
- Strong software engineering fundamentals: clean, maintainable code; pragmatic testing; effective code review.
- Comfort mentoring/pairing with engineers to up‑skill the team.
Desirable
- Experience with Amazon Managed Service for Apache Flink and/or running Flink on EKS/ECS.
- Experience with MongoDB or MongoDB Atlas for low‑latency, online‑serving use cases.
- Infrastructure‑as‑code (CloudFormation) and modern observability tooling (CloudWatch, Grafana, OpenTelemetry, Splunk).
Indicative technology stack
- Java, Python
- Apache Flink; Kafka / AWS MSK
- AWS: IAM, VPC, S3, CloudWatch; plus a Flink runtime (managed service and/or EKS/ECS depending on solution)
- MongoDB / MongoDB Atlas (online store)
- CircleCI and IaC: GitHub; CloudFormation
