Job description

You will own the backend services that power client onboarding, account provisioning, and back-office workflows across our platform. Expect heavy PHP/Laravel work, Postgres schema and query design, and engineering for correctness under concurrent load.

What you'll own

• Design and implement APIs and background workers used during onboarding and account provisioning.
• Ensure transactional integrity, idempotency, and safe retry behaviour across services.
• Build and maintain integrations with external providers and broker systems (KYC, broker APIs, reporting endpoints).
• Improve database schemas, migrations, and Postgres performance for high-concurrency paths.
• Maintain observability: metrics, tracing, structured logs, and on-call runbooks.

A typical week

• Debug production incidents and ship safe, tested fixes during on-call rotations.
• Review pull requests and pair on design trade-offs for reliability and correctness.
• Write and maintain unit, integration, and load tests; run schema migrations with care.
• Collaborate with client success and operations to iterate on edge cases surfaced by real customers.

What we look for

• Solid production experience building services with PHP/Laravel and Postgres.
• Practical knowledge of concurrency control: transactions, advisory locks, and optimistic patterns.
• Familiarity with queues, background processing, and idempotent job design (RabbitMQ/Redis/Kafka or similar).
• Clear communicator who documents designs, mentors teammates, and prioritises reliability over shortcuts.
