Project: HR SaaS for the public sector. We are looking for a Senior Database Engineer to execute a production database migration from on-premises Microsoft SQL Server to Amazon RDS for a large HR/Learning SaaS platform serving public-sector and government agencies. You will own the migration mechanism end-to-end: moving multiple active OLTP databases with a near-zero-downtime cutover and a verified rollback path. 

This is a hands-on delivery role embedded in a cross-functional team (Backend, DevOps, and the client's existing DBA and QA teams). Beyond the migration itself, you will diagnose and resolve database-layer issues that surface during parallel run and cutover (latency, connection routing, read-only replica behavior). The platform's longer-term direction includes introducing PostgreSQL alongside SQL Server, so experience with a polyglot estate is a strong plus.

Key Responsibilities:

• Execute the migration of the OLTP database from on-prem SQL Server to Amazon RDS for SQL Server (Multi-AZ)  for dependent products.
• Provision and configure RDS instances (Enterprise Edition for AG support), parameter groups, option groups, backups, and Multi-AZ HA across all environments.
• Validate RDS feature compatibility: Change Tracking (required for downstream ETL) and CLR SAFE assemblies; prepare and cost the fallback path
• Diagnose and fix database-layer issues during parallel run and cutover: Transit Gateway / cross-network latency, connection-string and read-only routing, command timeouts, and accidental writes to read replicas.
• Define and rehearse cutover and rollback runbooks (failover/failback timings, RPO/RTO targets, validation steps); support QA parity testing and performance baselining
• Establish monitoring, alerting, and backup/recovery (CloudWatch, Performance Insights, point-in-time recovery) for the migrated databases.

Tools and skills you will use in this role:

• Microsoft SQL Server (T-SQL, Always-On Availability Groups, Change Tracking, CLR)
• Amazon RDS for SQL Server (Multi-AZ), AWS DMS
• AWS (VPC/Transit Gateway, S3, CloudWatch, Performance Insights, IAM)
• Nice to have: Infrastructure-as-Code (AWS CDK)
• Nice to have: PostgreSQL / Amazon RDS / Aurora PostgreSQL

Requirements:

• 5+ years as a DBA / Database Engineer in production environments.
• Deep Microsoft SQL Server administration expertise: Always-On Availability Groups, replication, backup/restore, log shipping, Change Tracking, performance tuning, and T-SQL.
• Proven experience migrating SQL Server workloads to AWS, ideally Amazon RDS for SQL Server, including AG-based and/or DMS-based approaches.
• Strong understanding of HA/DR, RPO/RTO, cutover, and rollback planning for active production systems.
• Hands-on AWS experience: RDS, networking (VPC, Transit Gateway), S3, monitoring, IAM.
• Ability to troubleshoot database connectivity, latency, and routing issues in hybrid (on-prem + cloud) topologies.
• Experience working alongside a client-side DBA team and coordinating phased, multi-environment rollouts.
• English: Upper-Intermediate or higher.

Nice to have:

• PostgreSQL administration and SQL Server-to-PostgreSQL migration experience (schema, stored procedures, data-type mapping, dual-write/cutover).
• Familiarity with EF Core / Npgsql and .NET application data layers.
• Experience with AWS DMS for heterogeneous migrations.
• Infrastructure-as-Code with AWS CDK; CI/CD-driven database migrations.
• Exposure to regulated/compliance environments (e.g. FedRAMP).

We offer*:

• Flexible working format - remote, office-based or flexible
• A competitive salary and good compensation package
• Personalized career growth
• Professional development tools (mentorship program, tech talks and trainings, centers of excellence, and more)
• Active tech communities with regular knowledge sharing

Client & Project

Our client is a global leader in corporate brand protection and domain management, serving Fortune 500 and large enterprises with domain registration, online brand monitoring, and anti-counterfeiting services. Following the integration of two business units, the client is consolidating two legacy client portals into a single modern platform - completing the target portal, bringing it to feature parity with the legacy system, and migrating clients onto it ahead of a delivery deadline.

Stack: PHP 8.x (Laravel), RabbitMQ, MySQL, Nuxt.js (Vue.js), AWS.

Profile We're Looking For

A Solutions Architect with PHP background who has carried enterprise systems through real-world consolidation - splitting monoliths, migrating off legacy platforms, and integrating disparate systems - and who brings an enterprise mindset: designing for reliability, maintainability, and scale, and making trade-offs explicit rather than quietly cutting corners.
 

Key Responsibilities

• Own architecture and technical direction for the portal feature-parity and consolidation workstream, designing toward a single, scalable PHP/Laravel platform on AWS.
• Lead delivery of a Scrum team (PHP developers + QA): break epics into technical tasks, drive estimation and sprint planning, and own code quality through reviews and pair programming.
• Architect and oversee data migration and cutover: client migration scripts, entity-ID mapping tables, sync services, and API shims supporting the ongoing migration (including EPP/registry messaging).
• Design event-driven flows on RabbitMQ with proper error handling and back-pressure — avoiding failure modes such as silent error-code surfacing to users or runaway ticket generation from failed background messages.
• Embed observability (Datadog, AWS monitoring) so issues can be triaged and resolved quickly in production.
• Drive test automation strategy with QA to remove regression bottlenecks, and modern CI/CD practices.
• Surface technical risks and trade-offs early; capture deferred work as tracked tech debt rather than hidden corner-cutting.
• Align with client engineering leadership across US / UK / Brazil on technical direction and governance cadence.

Required Skills

• 8+ years of commercial software engineering, with strong hands-on PHP (PHP 8.x, Laravel or comparable modern frameworks).
• Proven track record in platform migrations — legacy-to-modern transitions, monolith-to-microservices decomposition, and running old and new systems in parallel during cutover.
• Strong integration background: API and event-driven integration, middleware/BFF patterns, and data synchronization (CDC tools such as Oracle GoldenGate / Debezium, or integration platforms such as MuleSoft / Boomi).
• Solid RabbitMQ and event-driven architecture experience.
• Strong MySQL skills — schema design, query optimization, performance tuning.
• Hands-on AWS experience, including migration of workloads/accounts and modern deployment patterns.
• Demonstrated technical leadership — mentorship, code reviews, and architectural decision-making.
• Excellent English; experience in a distributed, multi-timezone Agile / Scrum / Kanban setting.

Nice to Have

• Background in Java enterprise systems (the integration/migration heritage many of our strongest candidates bring), and ERP/commerce platform experience (SAP, SAP Commerce Cloud).
• Experience with AI-assisted development tools (Claude, Copilot, Cursor).
• SaaS, multi-tenant, or large-scale B2B portal experience.

We offer*:

• Flexible working format - remote, office-based or flexible
• A competitive salary and good compensation package
• Personalized career growth
• Professional development tools (mentorship program, tech talks and trainings, centers of excellence, and more)
• Active tech communities with regular knowledge sharing
• Education reimbursement
• Memorable anniversary presents
• Corporate events and team buildings
• Other location-specific benefits
