Contract Labview Test Engineer information
What is the difference between Contract Labview Test Engineer vs Contract Test Engineer?
| Aspect | Contract Labview Test Engineer | Contract Test Engineer |
|---|---|---|
| Credentials | Experience with LabVIEW, testing, and automation tools | General testing experience, sometimes with specific tools like LabVIEW |
| Work Environment | Electronics, embedded systems, or hardware testing labs | Varies across industries, including software, hardware, and systems testing |
| Industry Usage | Common in aerospace, defense, and electronics sectors | Widely used across multiple industries including manufacturing and software |
The Contract Labview Test Engineer specializes in testing hardware and systems using LabVIEW software, often within electronics or aerospace industries. In contrast, the Contract Test Engineer has broader testing responsibilities across various industries, sometimes using different tools. Both roles require testing skills, but the LabVIEW focus makes the Contract Labview Test Engineer more specialized in automation and hardware testing environments.

Posted 11 days ago
Job description
We are seeking an experienced, hands-on Senior .Net Lead to contribute to the development of our engineering frameworks, with a strong focus on microservice architecture. This senior engineering leadership role merges hands-on technical contribution with organizational accountability. The ideal candidate will remain deeply involved in the code and architecture while simultaneously owning the platform strategy, defining engineering standards, and guiding a scrum team in developing core functionalities within the payments lifecycle.
Key Responsibilities
1. Hands-On Technical Contribution & System Design
- Actively code in .Net developing reusable frameworks while performing system design, architecture reviews, and code reviews for the core cheque payment platform.
- Contribute to the design of distributed, fault-tolerant, real-time systems for high-volume, low-latency transaction processing.
- Write, review, and refactor production-grade code in .Net setting a high technical standard for the team.
- Independently design event-driven, microservices-based architectures utilizing REST APIs, .Net. React knowledge is a plus.
- Apply hands-on experience with Kafka, including message schema design, topic partitioning, consumer group strategies, and fault-tolerant processing.
- Design and govern data architecture across Oracle (SQL) and MongoDB (NoSQL), covering schema design, indexing strategies, query optimization, and data consistency patterns.
- Champion continuous development, feature flags, and progressive delivery, contributing to the design and optimization of CI/CD pipelines.
- Produce and review Architecture Decision Records (ADRs) and technical design documents for key platform components.
2. Engineering Excellence & Quality
- Maintain and enforce engineering standards within the scrum team, including Test-Driven Development (TDD), reusable framework development, CI/CD, secure coding, and observability.
- Conduct code reviews for critical platform components, providing detailed technical feedback to enhance team quality and capacity, ensuring the development of scalable and reusable services.
- Drive the adoption of AI-powered quality practices, including leveraging tools like GitHub Copilot for coding, utilizing LLMs (Gemini experience preferred) to improve payment processing quality, and implementing automated test script generation and vulnerability remediation.
- Lead performance engineering initiatives, including profiling JVM-based applications identifying performance hotspots, and optimizing critical settlement processing paths.
- Own the security and compliance posture of the cheque payment platform by participating in threat modeling, vulnerability assessments, and secure design reviews.
- Ensure all engineering delivery aligns with Citi Engineering Excellence Standards, including CI/CD, DevOps, cloud-native practices, and modern ways of working.
3. Platform Strategy & Domain Ownership
- Define and own the engineering roadmap for modernizing the cheque payment platform, migrating global components from monolithic mainframe and legacy applications to a reusable microservices architecture.
- Develop strong domain knowledge in the payment lifecycle, settlement, and cheque image processing to inform sound engineering decisions.
- Own the platform's SLA commitments, driving architectural decisions to meet availability, throughput, and latency targets.
- Develop cross-platform integration by governing API contracts, data flows, and system dependencies across the Payments, Settlements, DDA, and Data Lake ecosystems.
- Drive capacity planning and investment prioritization, making informed decisions on platform scaling, technology refresh, and resource allocation.
- Partner with Operations, Risk, Compliance, and Business teams to ensure the platform meets all regulatory requirements and business needs.
4. Leadership & Stakeholder Engagement
- Act as the primary engineering point of contact for the core Cheque Processing pillar, engaging with senior business, technology, and operations stakeholders.
- Clearly communicate platform health, delivery progress, engineering strategy, and risks to senior leadership.
- Partner with Product, Operations, Risk, Finance, and Compliance teams to align engineering priorities with business and regulatory needs.
- Demonstrate the ability to pivot direction to meet timelines and delivery commitments with tactical solutions, while maintaining a clear vision for strategic platform development.
Skills and Qualifications
1. Core Programming & System Architecture
- .Net: 10+ Extensive hands-on experience in high-throughput, production-grade .Net engineering, including JVM performance tuning.
- API Development: Hands-on experience building RESTful APIs with frameworks such as Spring MVC or Spring Boot.
- Microservices Architecture: Proven experience designing microservices ecosystems, including service decomposition, API design, inter-service communication, and cloud engineering.
- Event-Driven & Messaging Systems: Deep, hands-on expertise in Kafka, including topic design, partitioning, consumer groups, exactly-once semantics, and high-throughput stream processing.
- High-Performance Computing: Hands-on experience with profiling and optimization, including JVM tuning, garbage collection (GC) optimization, thread management, and memory profiling.
- High Availability & Fault Tolerance: Practical experience designing resilience patterns such as circuit breakers, bulkheads, failover, and disaster recovery.
- Databases: Hands-on expertise in Oracle (SQL) and Microsoft SQL for schema design, query optimization, and indexing, as well as MongoDB (NoSQL) for document modeling, aggregation pipelines, sharding, and replica sets.
2. Cloud & DevOps
- Cloud-Native Engineering: Hands-on experience with OpenShift/AWS, Kubernetes, and Docker for container orchestration, autoscaling, and cloud-native deployment.
- CI/CD & DevOps: Experience designing and owning CI/CD pipelines aligned with enterprise-level Engineering Excellence Standards. Experience with tools like Jenkins and Gradle/Maven.

- Agile at Scale: Experience with Agile/SAFe delivery at the program level, including PI planning, cross-team dependency management, and delivery governance.
Good-to-Have Skills
- ML Integration: Hands-on experience with real-time ML model serving, including feature stores, online inference, and model monitoring.
- AI Frameworks: Familiarity with Retrieval-Augmented Generation (RAG) patterns, vector databases (e.g., Pinecone, Weaviate), or agentic AI frameworks (e.g., LangChain, AutoGen).
- MLOps: Knowledge of MLOps practices such as model versioning, deployment pipelines, and production model monitoring.
- Resilience Testing: Experience with chaos engineering and resilience testing, including fault injection and production readiness reviews.
