## Job description

What You’ll Do: We are seeking a highly motivated and experienced Senior Software Engineer to join our fast-growing team. You will design and build large-scale, multi-tenant SaaS systems that power Nue's core revenue workflows. You'll work across a powerful stack — Java/Spring Boot, Node.js/React, modern databases (SQL & NoSQL), event streaming platforms, and cloud infrastructure (AWS, Snowflake) — solving complex challenges in scalability, automation, and financial workflows.

Responsibilities:

- Design, architect, and implement large-scale, multi-tenant SaaS applications with a shared-nothing architecture based on the Spring Boot framework, leveraging microservices (API gateway, service registry, service monitoring), and event-driven patterns.
- Own end-to-end feature delivery: scoping, design, implementation, testing, rollout, and operations.
- Define and evolve domain models and data schemas to ensure accuracy, auditability, and long-term maintainability.
- Build and maintain high-throughput, low-latency services that process large volumes of events with strong consistency and reliability guarantees.
- Design and implement event-driven workflows using message queues and streaming platforms (e.g., Kafka, Kinesis, RabbitMQ, SNS/SQS, Webhooks).
- Drive technical excellence and best engineering practices — design reviews, RFCs, continuous integration, code reviews, observability, CI/CD.
- Provide architecture and technical guidance, and mentor other engineers in distributed systems design, database modeling, and scalability patterns.
- Establish and maintain SLIs/SLOs (latency, throughput, accuracy, availability) for production services and continuously improve them.
- Collaborate closely with Product and cross-functional teams to translate business requirements into robust, fault-tolerant system designs.
- Deliver high-quality design and code using modern tools and agile methodologies including TDD, CI, refactoring, and code reviews.
- Stay current with relevant technologies (event streaming, data infrastructure, security, AI-assisted development) and apply them pragmatically to Nue's SaaS platform.

What You'll Bring:

- Bachelor's degree in Computer Science, Software Engineering, or a related field (or equivalent practical experience).
- 5+ years of professional software development experience, designing and building large-scale, distributed backend systems.
- 5+ years of experience with Java (or JVM languages) and building microservices on frameworks such as Spring Boot.
- Deep understanding of relational databases (e.g., PostgreSQL, MySQL) including schema design, indexing, and performance optimization.
- Experience with multi-tenant and/or sharded database architectures and strategies for scale and isolation.
- Hands-on experience with event-driven architectures and streaming or messaging platforms (e.g., Kafka, Kinesis, RabbitMQ, Pub/Sub).
- Solid understanding of data consistency models, idempotency, exactly-once / at-least-once processing, and eventual consistency patterns.
- Experience with at least one major cloud provider (AWS, GCP, or Azure) and building cloud-native services (containers, serverless, managed data services).
- Strong SQL skills and familiarity with database performance profiling and tuning.
- Experience with concurrent programming and thread safety in production applications.
- Experience with observability (metrics, logs, traces) and diagnosing performance and reliability issues in production.
- Test-driven mindset, with hands-on experience writing and maintaining automated unit, integration, and end-to-end tests; familiarity with test automation frameworks such as Playwright or similar tools.
- Strong portfolio or examples of past projects and code.
- Strong communication and collaboration skills, with the ability to explain complex systems to both technical and non-technical stakeholders.
- Enthusiasm for working in a fast-paced, startup-like environment and taking end-to-end ownership of critical systems.

Bonus Points (optional):

- Experience with finance, billing, subscriptions, payments, or revenue-lifecycle systems in a SaaS or financial-services context.
- Experience with Snowflake or other modern data warehouses for reporting, analytics, and reconciliation use cases.
- Familiarity with NoSQL or time-series databases and when to apply them alongside relational systems.
- Experience with enterprise-scale systems and high-volume transactional workloads.
- Understanding of compliance, security, and auditability concerns in financial systems (e.g., PCI considerations, data retention, audit trails).
- Experience integrating with Salesforce or other CRM/ERP platforms.
- Demonstrated ability to effectively use AI-assisted development tools (e.g., Claude Code, Codex, or similar) to accelerate development, improve code quality, debug complex issues, and explore system designs.
- Strong attention to detail, ownership mindset, and comfort operating in ambiguous, evolving product domains.
