Jose Milanes — Software Engineer

I’m Jose, a software engineer with 3+ years of professional experience working on distributed systems and high-impact platform teams.

At Atlassian, I work on the Trusted Change Platform in the Release Tracks team, a Tier 1 service that manages when customers receive changes and new features for apps and sandboxes in their organization.

Currently building at Atlassian

Built with purpose.
Backed by impact.

JAN 2025 — PRESENTCURRENT ROLE

Software Engineer II

Building the systems and tools that make enterprise engineering more reliable, secure, and productive.

  • Drove an organization-wide developer productivity initiative that raised deployment pipeline reliability from 70% to 90% via redesigned PR verification and parallel test execution.
  • Led an observability and performance uplift that reduced high-severity incidents by 50%, introducing SLOs, automated alerting, and standardized metrics/logging practices adopted across a monorepo.
  • Migrated a microservice into a monorepo for 30+ engineers with zero downtime, preserving full commit history and tooling parity (coverage scanning, deploy pipelines) by keeping the old deployment live during cutover.
  • Built an orchestration API (Kotlin, Spring Boot, PostgreSQL, Temporal) sequencing Enterprise Posture Management's batch jobs topologically with job-ID tracking, eliminating concurrency-driven data corruption.
  • Built and deployed an internal MCP server (Python, AWS) letting 500+ engineers and AI agents self-serve compliance answers instantly, replacing Slack/ticket requests that took 1+ day.
  • Built automated data pipelines (Java, AWS S3, Airflow, DBT) with an AI agent for onboarding new tables, powering Release Tracks dashboards that gave leadership product insights and validated customer feedback.
  • Built a custom distributed locking mechanism in Java and PostgreSQL using serializable transaction isolation to eliminate data inconsistencies and improve concurrency control for a high-traffic enterprise service.
  • Engineered a standardized encryption framework (Java, AES-GCM, HashiCorp Vault) across 7+ platform services, cutting per-service encryption effort and hardening APIs via opaque, tamper-resistant cursors.

JUL 2023 — JAN 2025

Software Engineer I

Creating a stronger foundation for enterprise compliance and internal platforms.

  • Improved performance and maintainability across 4 internal applications by standardizing GraphQL schema design and resolver logic, accelerating development cycles by up to 50%.
  • Designed a new system for on-demand cloud resource inventory reporting and automated 4 recurring reports, eliminating a week of manual effort per cycle and supporting FedRAMP Moderate compliance.
  • Built and shipped an API to migrate 1M+ records from a legacy compliance dashboard to a new data model, unblocking support for additional industry-wide compliance standards.

MAY 2022 — AUG 2022

Software Development Engineer Intern

Making data more consistent and development environments more dependable.

  • Built data migration scripts in Python and Apex to move 200+ analytic reports between environments, improving environment parity for 15+ developers and testers.
  • Reduced concurrency-related data inconsistencies by implementing queries with strict isolation levels (serializable, repeatable read) using SOQL and Apex DML.
