Software Engineer

dependency on legacy systems Role Overview As a Senior Software Engineer on this team, you will own the design and delivery of core backend services, drive integration architecture with third-party platforms, and help establish the engineering patterns. You will work closely with product, design, and customer-facing teams to ensure what gets built solves real problems elegantly. Key Responsibilities Platform & Backend Engineering Design and build scalable, highly available Java microservices on AWS from scratch Define and own the data model for time tracking entities - entries, projects, users, billing cycles Architect RESTful and event-driven APIs consumed by web, mobile, and third-party clients Own the full AWS infrastructure for your services: Lambda, ECS/EKS, RDS/Aurora, SQS, S3, CloudWatch Implement CI/CD pipelines using GitHub Actions or AWS Code Pipeline, with automated testing gates Integrations Build bi-directional sync between the time tracking platform and Airtable bases via the Airtable API Integrate with Linear to link time entries to issues, projects, and cycles - keeping both systems in sync Develop Slack workflows: slash commands, interactive modals, notifications, and Bolt-based event subscriptions Design an integration framework that can onboard new third-party connectors without re-architecting core services Handle webhooks, OAuth 2.0 flows, token management, and rate limiting for all external platforms AI-First Development Use AI coding assistants (e.g. GitHub Copilot, Claude, Cursor) as a core productivity tool throughout development Implement AI-powered features: intelligent time entry suggestions, anomaly detection, natural language querying of time data Leverage LLMs for smart auto-categorization of time entries based on calendar, Linear activity, or Slack context Contribute to prompt engineering, RAG pipelines, or fine-tuning workflows as the product roadmap evolves Evaluate and recommend AI/ML services (AWS Bedrock, SageMaker, OpenAI, Anthropic APIs) appropriate to each use case Quality & Collaboration Write clean, well-tested Java code - unit, integration, and contract tests are non-negotiable Participate in architecture reviews, PR reviews, and cross-functional planning sessions Contribute to runbooks, ADRs (Architecture Decision Records), and internal documentation Required Qualifications Core (Must-Have) ~5+ years of professional software engineering experience ~ Backend: Strong Java proficiency ~ Spring Boot or Quarkus for microservices; experience with reactive frameworks (Vert. xbhjioe x, WebFlux) a plus ~ Cloud: Deep AWS expertise ~ Hands-on experience with Lambda, ECS or EKS, RDS/Aurora, SQS/SNS, API Gateway, IAM, CloudFormation or CDK ~ APIs: REST API and event-driven architecture design and implementation ~ OAuth 2.0, webhook design, idempotency, and third-party API integration patterns ~ AI Tooling: Demonstrable AI-first mindset ~ Re
