高级数据库开发工程师（Oracle & PostgreSQL）
Senior Database Developer (Oracle & PostgreSQL)
Mactores 是一家以代理为中心的 AWS 现代化公司。大多数现代化工作无法交付，停滞在试点阶段，延期一年，或最终超出三倍预算。我们致力于将其交付：生产系统运行，遗留系统退役，成果可衡量。我们的交付基于 Aedeon，这是由 Mactores 创始人姐妹公司开发的代理平台，该平台吸收了 60–70% 的重复性工作，包括发现、依赖映射、验证、测试生成，传统咨询公司会按人工小时计费。前移部署的工程师负责其余部分：架构、判断和切换，在合同中承诺的日期内完成。
我们正在寻找一位经验丰富的高级数据库开发人员，领导并支持从 Oracle 到 PostgreSQL/Aurora PostgreSQL 的迁移项目。该职位涉及 SQL 重构、模式转换、DMS 操作、性能调优以及上线后的稳定化工作的深入实际操作。候选人将与应用团队、云工程师和利益相关者紧密合作，确保迁移过程顺利、高性能且合规。
你将负责：
- 将 Oracle SQL、PL/SQL 和数据库对象重构和转换为 PostgreSQL 兼容的 SQL/PLpgSQL。
- 分析并修复 AWS SCT（Schema Conversion Tool）的发现结果和限制。
- 管理和维护 Flyway 迁移代码库（版本化脚本、可重复迁移、回滚）。
- 识别、排查并修复与数据库相关的应用缺陷。
- 对 PostgreSQL 执行查询优化（执行计划、索引策略、查询重写）。
- 在全量加载和 CDC 阶段支持和监控 AWS DMS。
- 诊断并解决 DMS 数据和性能问题。
- 在 Oracle 和 PostgreSQL 之间执行数据验证和对账。
- 与应用团队协作，统一 SQL 行为和性能预期。
我们寻找：
- 计算机科学或相关领域的学士学位。
- 5 年以上 Oracle/PostgreSQL DBA 和数据库开发经验。
- 对 Oracle 数据库和 PostgreSQL / Aurora PostgreSQL 有丰富经验。
- 具备 Oracle 到 PostgreSQL 迁移的实际经验。
- 高级 SQL 和查询性能调优技能。
- 使用 AWS SCT 和 AWS DMS 的经验。
- 了解 Flyway/Liquibase 或类似模式迁移工具。
- PostgreSQL 内部机制：索引、统计信息、执行计划。
- AWS 服务：RDS/Aurora、CloudWatch、IAM（优先）。
如果你具备以下条件，我们将更青睐你：
- 熟悉自动化和配置管理

Mactores is the agent-native AWS modernization firm. Most modernization work doesn't ship, it stalls in pilots, slips a year, or lands at three times the budget. We exist to ship it: production systems running, legacy retired, outcomes measured. Our delivery is built on Aedeon, the agent platform built by Mactores' founders' sister company, which absorbs the repetitive 60–70% of engagement work, discovery, dependency mapping, validation, test generation, that traditional consulting bills human hours against. Forward-deployed engineers own the rest: architecture, judgment, and cutover, on dates we commit to in the contract.
We are seeking an experienced Senior Database Developer to lead and support Oracle to PostgreSQL/Aurora PostgreSQL migration initiatives. The role involves deep hands-on work across SQL refactoring, schema conversion, DMS operations, performance tuning, and post–go-live stabilization. The candidate will work closely with application teams, cloud engineers, and stakeholders to ensure a smooth, performant, and compliant migration.
What you will do?
- Refactor and convert Oracle SQL, PL/SQL, and database objects to PostgreSQL-compatible SQL/PLpgSQL.
- Analyze and remediate AWS SCT (Schema Conversion Tool) findings and limitations.
- Manage and maintain Flyway migration codebase (versioned scripts, repeatable migrations, rollbacks).
- Identify, troubleshoot, and fix database-related application bugs.
- Perform query optimization for PostgreSQL (execution plans, indexing strategies, query rewrites).
- Support and monitor AWS DMS during full load and CDC phases.
- Diagnose and resolve DMS data and performance issues.
- Perform data validation and reconciliation between Oracle and PostgreSQL.
- Collaborate with application teams to align SQL behavior and performance expectations.
What are we looking for?
- Bachelor's degree in Computer Science or a related field.
- 5+ years of experience as an Oracle/PostgreSQL DBA and database developer.
- Strong experience with Oracle Database and PostgreSQL / Aurora PostgreSQL.
- Hands-on expertise in Oracle to PostgreSQL migration.
- Advanced SQL and query performance tuning skills.
- Experience with AWS SCT and AWS DMS.
- Knowledge of Flyway/Liquibase or similar schema migration tools.
- PostgreSQL internals: indexing, statistics, execution plans.
- AWS services: RDS/Aurora, CloudWatch, IAM (preferred).
You will be preferred if:
- Familiarity with automation and configuration management tools, such as Ansible, Chef, or Puppet.
- Familiarity with IAAC tools such as Terraform, CloudFormation.
- Familiarity with CI/CD implementation tools like Liquibase/Flyway.
- AWS Certified Database – Specialty.
- AWS Certified Solutions Architect.
