Software Engineer II

Reflexive Concepts is seeking a skilled Software Engineer II (Back-End, Hadoop & Microservices) to join our team!Reflexive Concepts is looking for a Software Engineer II with strong back-end development experience - particularly in Hadoop and microservices - to join a small, high-impact software team. If taking ideas from concept to working prototype in fast, iterative cycles excites you, and you enjoy solving complex problems in distributed systems, this role will give you the opportunity to have outsized impact on how the organization operates. You will work as a hands-on engineer on a close-knit team, designing and building scalable back-end services and data-intensive systems that support mission-critical applications.Responsibilities:Design, develop, maintain, and enhance complex back-end software systems based on documented requirementsImplement services and data pipelines using Hadoop and related big-data technologiesBuild and evolve microservices-based architectures, including service boundaries, APIs, and inter-service communication patternsUtilize sound software design and development methodologies to build, integrate, and execute simulations in development and test environmentsProvide input to system and software design, including hardware/software trade-offs, software reuse strategies, and effective use of COTS/GOTS components versus new developmentPerform requirements analysis and synthesis from system level down to individual services and modulesImplement and consume RESTful APIs to integrate back-end services with other systems and client applicationsContainerize services (e.g., Podman/Docker) and deploy them to orchestrated environments (e.g., Kubernetes)Diagnose and resolve complex issues in distributed systems, including performance analysis, latency reduction, and scalability tuningApply strong analytical troubleshooting and performance evaluation techniques across the stackCollaborate with team members and stakeholders to refine requirements, estimate work, and deliver incremental value Requirements:Active TS/SCI with Full-Scope polygraphBachelor's degree in Computer Engineering, Computer Science, Electrical Engineering, Math, or Physics - or an equivalent combination of education, training, and experienceMinimum 14 years of relevant experience in software engineering, modernization, or solution architecture Required Skills:Strong Java development skills for back-end and service-layer implementationsExperience building and consuming RESTful servicesHands-on experience with containers (Podman and/or Docker)Experience with container orchestration platforms such as KubernetesPractical experience designing and implementing microservices architecturesBack-end development experience with Hadoop or similar big-data processing frameworks Familiarity with Two or More of the Following:Processing paradigms: machine learning workflows, streaming data processing, and/or batch processing pipelinesData stores: MongoDB, ArangoDB, Redis, PostgreSQL (data modeling, performance tuning, and operations) Desired Skills:Experience deploying and operating applications in cloud environments such as AWS or on hyper-converged infrastructure (HCI)Familiarity with observability tools (logging, metrics, tracing) for distributed systemsExperience working in agile or iterative development environments
