Discuss your hiring requirement ↗We assess relevant production responsibilities, evidence of implementation work and technical discussions with your team. A list of tools alone is not proof of experience.
Under staff augmentation the client usually directs the backlog and reviews. Team leadership and project-delivery ownership must be agreed separately.
The profiles indicate sourcing options, not verified available individuals. Availability, start date and fees are confirmed for the actual request.
Describe your PHP version, Symfony or Laravel framework, transaction volumes, MySQL behavior, testing and existing system boundaries. We help source PHP engineers with relevant production responsibilities; the Atolls reference illustrates documented high-traffic commerce experience.
For a long-running PHP platform, agree code ownership, security, release practices, migration work and the expected level of independence before sourcing. A dedicated specialist works alongside your team; larger scopes may call for a coordinated development group.
Remote recruitment requires agreement on working hours, access controls, development environment, security, language and handover. The exact country, start date, cost and individual availability are confirmed for the actual requirement.
/ Engineering in production
Five Onectus engineers are embedded in Atolls engineering teams, contributing to established shopping and deals platforms used by millions of people. Their work spans Vue.js interfaces, PHP application services, MySQL-backed product workflows, modernization, testing and production-aware releases. It is experience with real systems, established teams and sustained delivery—not an isolated demonstration.
Atolls operates the platforms; Onectus contributes embedded engineering talent and specialist recruitment.

Production context
Embedded Onectus engineers
Contributing across established commerce products and technologies.
/ Engineering responsibilities
The right senior engineer understands legacy constraints, operating characteristics, dependencies and the commercial flows that must keep working during change.
PHP 8+, application boundaries, dependency management, modular services and maintainable code across mature repositories.
MySQL schema evolution, indexes, query plans, transactions, locking and safe data migrations for active product workloads.
Identify expensive request paths, cache invalidation, Redis or equivalent stores, queue-backed workloads and throughput bottlenecks.
REST APIs, authentication, external services, event-driven workflows and failure-safe integration boundaries.
Work across Laravel, Symfony or existing frameworks when applicable; refactor gradually and migrate without destabilizing the product.
Testing, profiling, observability, CI/CD, release safety and collaboration with QA and infrastructure teams.
/ Real-world requirements
Improve architecture and developer productivity without interrupting revenue-critical production workflows.
Trace slow paths through PHP, SQL, caching and third-party calls as traffic and product complexity increase.
Maintain business rules, data consistency, payment or catalog APIs, and predictable service contracts.
Add senior ownership for code reviews, incident analysis, architectural decisions and engineering mentorship.
/ Seniority assessment
Years in PHP alone do not establish seniority. Our screening conversations focus on the systems candidates have changed, operated and supported.
Can the engineer explain boundaries, dependencies, tradeoffs and migration choices made in real products?
Can they reason about query plans, N+1 patterns, locks, cache invalidation, profiling and production symptoms?
How do they handle tests, rollout strategy, rollback, authorization, observability and incidents?
Can they guide code review, communicate constraints and improve delivery within an established product team?
Which framework versions, infrastructure, time-zone overlap, team practices and role responsibilities are relevant?
/ Engagement model
Our active engineer network and regional recruiting channels support role-specific sourcing. You define the stack, technical responsibilities and working model. We match production experience, coordinate interviews and prepare an integration with your developers.
Share PHP version, frameworks, database scale, traffic patterns, key integrations and delivery ownership.
Engage active talent relationships, regional recruiters and appropriate PHP engineering communities.
Discuss real delivery and operational experience and coordinate technical interviews with your team.
Confirm availability, engagement terms, onboarding, access, code review and release responsibilities.
/ Common questions
Yes. Tell us which framework, versions and production responsibilities matter. We can include relevant Laravel or Symfony experience in the sourcing brief.
That is the focus of this role. We evaluate experience with mature codebases, performance, database behavior, releases and collaboration before introducing candidates.
Yes. Atolls is a relevant Onectus engineering engagement. We can target prior work on catalog, listings, discovery, community or transactional backend systems as needed.
Both. We can source an individual senior PHP engineer or coordinate complementary frontend, QA, database and infrastructure specialists.
PHP/framework versions, services and databases, production scale, the problems to solve, team composition, language, location expectations and preferred start.
/ Onectus · TEAMS
