Staff Software Engineer

Position: Staff Software Engineer

Job Location: 10900 NE 4th St., Bellevue, WA 98004

Duties: Assess software gaps, updates, and modifications between the customer and business expectations and the existing software product and solutions (in case of agile methodology, for the iteration). Classify the requirements into applicable types. Anticipate the solution risks and issues during requirements gathering phase, inform relevant stakeholders and recommend corrective steps. Contribute to the creation of user stories for software components, applications, or complex. Assist in design of software solutions such that the processes and software applications work in tandem for specific software components and modules of a product. Evaluate trade-offs while designing a component based on the business requirements. Assist in conversion of HLD (High Level Design) to create detailed designs using mock screens, pseudo codes, and detailed functional logic of the modules for specific modules and components of a product. Create and configure minimalistic software code for entire the software component or software application and ensure the components are meeting business and technical requirements, non-functional requirements, low-maintenance, high-availability, and high-scalability needs. Assist in the selection of appropriate languages and software development standards and tools for software coding and configuration. Take initiative to learn the fundamentals of different coding languages and frameworks that would be useful for future scope of work. Build scripts for automation of repetitive and routine tasks in CI/CD (Continuous Integration/Continuous Delivery), testing, or any other process. Implement telemetry features as required independently. Ensure security policy requirements are properly applied to software components and applications during code development and configuration. Map the customer requirements into test objectives. Identify and create test cases for the component or module. Execute test cases to test the code and detect errors and defects for the entire component. Execute different types of testing using appropriate testing tools based on the testing needs. Track and analyze defects for the component or module and carry out regression testing to fix defects in all instances of code changes. Analyze defects from past software engineering solutions to avoid recurrence of similar defects. Troubleshoot performance and availability bottlenecks for the application. Conduct complex maintenance procedures for applications independently. Monitor and evaluate the performance of the application by tracking and analyzing appropriate metrics. Perform maintenance (corrective, adaptive, perfective) and re-engineering activities. Analyze application logs, maintenance activity data, and performance data and provide analysis. Evaluate change requests to identify those which are valid and feasible.

Skills required: Experience with defining the architecture blueprint, decomposing systems into multiple microservices and components and identifying the tech stack for the product in line with the business needs and technology strategy (UML, draw.io, mermaid.js, and C4-PlantUML). Experience with crafting effective prompts to guide language models toward desired outputs and analytical results (OpenAI LLMs and LangChain).  Experience with building structured pipelines for complex LLM-based RAG applications, with agents or multi-step reasoning systems (LangChain, LangGraph, and Milvus DB). Experience with designing object-oriented code designs and implementing them using suitable programming languages (OOPs). Experience with tracking system performance and diagnosing issues through real-time metrics, logs, and traces using Open Telemetry, Telemetry and Grafana. Experience with designing and building asynchronous microservice systems with REST APIs to enable communication between systems or services for high availability and throughput using FastAPI and Flask API message queues and brokers like Kafka. Experience with packaging applications into portable containers and managing them on a scale for consistent deployment and reliability across environments (Docker, Kubernetes, Helm, and Istio). Experience with managing code changes and automating software delivery using version control systems and CI/CD pipelines (GitHub and Jenkins). Experience with ensuring software reliability and maintainability through automated testing, test-driven development (pytest and unit test) and code quality enforcement (SonarQube, Pylint, Black, and PMD) tools. Experience with designing, implementing, and maintaining databases to ensure efficient data storage and retrieval (SQL Server). Experience with designing and maintaining caching systems to improve application performance by reducing database load and response time using Redis and Cassandra. Experience with optimizing query performance and data workflows for high-volume transactional systems (AzureSQL, Airflow, PgSQL query and index tuning). Experience with performing system modernization and refactoring of legacy monolithic components (coverage, cProfile, PMD, and VisualVM). Employer will accept any amount of experience with the required skills.
