We are looking for a Senior Java Developer / Tech Lead who will drive the technical implementation of a new enterprise‑grade integration and orchestration platform built using Java, Spring Boot and Temporal SDK. The person in this role will lead development activities, guide engineers in the team, ensure high‑quality code delivery, and contribute to key technical decisions. The platform integrates multiple information systems, exposes APIs and event‑driven flows, and executes business processes using a workflow orchestration engine. The Tech Lead will work closely with architects and product teams, ensuring that the delivered solution is performant, secure, maintainable, and aligned with overall architectural direction.

What project we have for you

Our customer is a multinational corporation with more than a century of history and offices in over 180 countries. Their most ambitious goal at the time is to introduce a range of Reduced-Risk Products (RRPs). The target audience is more than 1 billion consumers around the globe. IT platform hosts 700+ applications.
Intellia’s mission is to help the client with the engineering of a comprehensive software ecosystem for a game-changing IoT product on the margin of innovative consumer experience and cutting-edge technology. Our teams are involved in the engineering of core platform components for best-in-class eCommerce, Digital Marketing and IoT solutions. As a DevOps engineer, you will become a part of Core Architecture Team and be responsible for the architecture, implementation of best practices in our Digital Engineering Enterprise Platform.
The Platform is a set of services and internet applications that accelerate the development and delivery of software applications by taking care of common SDLC challenges. The Platform provides access and consumption for engineering teams to a set of services, technologies, practices for their development and for operating their application, ensuring a set of compliance and best practices.
Project is in production for 2+ years, being supported by multiple teams.

Our technical domains are:
– AWS cloud, partially Azure
– SSO, Organizations, Service control policies, access models.
– IAAC: terraform enterprise, terratest, chalice
– Serverless: lambda, step functions, wide range of misc automations, fargate
– System, Application, Network and security architectures
– Orchecstration: k8s (eks)
– SRE activities (logging, tracing, monitoring), OpsGenie, Splunk
– Hashicorp Vault
– Hybrid Networking

What you will do

· Lead and supervise the end-to-end implementation of Java/Spring Boot services, ensuring code quality, maintainability, and adherence to architectural standards

· Support developers in the team by providing technical direction, reviewing code, and resolving complex implementation challenges

· Implement workflow logic using orchestration frameworks (e.g., Temporal SDK), including workflows, activities, retries, compensation patterns, and error-handling strategies

· Ensure that service-to-service communication, API design, and event-driven interactions follow best practices for distributed systems and meet scalability and resilience requirements

· Apply secure-by-design principles, ensuring compliance with OWASP, secure coding practices, proper secrets management, and identity/access policies

· Collaborate with architects on solution design and translate architectural blueprints into actionable implementation tasks

· Ensure operational readiness of developed components by implementing logging, metrics, tracing, and applying observability patterns (OpenTelemetry, Prometheus, ELK)

· Work with DevOps engineers to optimize CI/CD pipelines, deployment processes, and runtime configurations in containerized environments (Docker, Kubernetes)

· Troubleshoot, profile, and optimize applications to improve performance, reliability, and resource efficiency

· Contribute to documentation, including technical guidelines, integration specifications, and runbooks

What you need for this

EXPERIENCE

· Extensive hands-on experience in Java and Spring Boot for building scalable, resilient, and maintainable backend services

· Proven background in developing distributed systems, asynchronous communication flows, and event-driven designs

· Experience implementing integrations, APIs, and messaging-based communication across multiple systems

· Solid understanding of security principles, identity/access control, and secure software lifecycle

· Experience with cloud environments (AWS), containerization, and Kubernetes-based deployments

· Exposure to observability platforms and telemetry standards (OpenTelemetry, Grafana, Prometheus, ELK)

· Experience mentoring developers, conducting code reviews, and leading technical discussions

SKILLS

· Excellent knowledge of Java, Spring Boot, and ecosystem libraries for enterprise-grade development

· Strong understanding of distributed systems, microservice architecture, resilience patterns, asynchronous messaging, including process orchestration, and event streaming

· Practical experience with workflow engines or orchestration frameworks implementation (preferably Temporal SDK) is considered as a plus

· Strong debugging, code-review, and performance-optimization skills

· Ability to clearly communicate technical decisions to developers and collaborate effectively with architects and product teams

· Ability to design and implement fault-tolerant flows including retries, compensation, dead-letter queues, and correlation mechanisms

· Knowledge of integration protocols and standards such as REST, gRPC, AMQP, JMS, and event-driven communication models

· Good understanding of software security, OWASP, encryption, secrets management, and IAM concepts

· Experience with containerization (Docker), orchestration (Kubernetes), and CI/CD practices
