CONTRACTOR – Senior Backend Developer (Go)
Senior Backend Developer (Go)
US-based, contract, remote
We are looking for a senior-level backend contractor to help improve and evolve
several production services by refactoring them toward a clearer, domain-oriented
architecture.
The work will focus on improving service boundaries, simplifying complex business
logic, and making key workflows easier to understand, test, and extend. One
important area involves rules-based processing, alarm generation, and user
notification flows. Another involves authorization and access-control related services.
The system processes tens of millions of messages per hour across Kafka-backed
services and must remain reliable, observable, and maintainable under sustained
production load.
Responsibilities
– Refactor existing backend services toward clearer domain boundaries and more
maintainable architecture.
– Improve complex business workflows related to rules, alarms, notifications,
authorization, and access control.
– Help separate domain logic from infrastructure and integration concerns.
– Improve testability, reliability, and operational clarity.
– Work incrementally within existing production systems without unnecessary rewrites.
– Collaborate with the engineering teams on design decisions, tradeoffs, and rollout
plans.
Required Experience
– Senior-level backend engineering experience with production business applications.
– Strong Go language experience.
– Strong experience refactoring complex services or legacy codebases.
– Practical understanding of domain-driven design, clean architecture, or similar
approaches.
– Experience with distributed systems and event-driven architectures.
– Experience with Kafka or comparable messaging systems.
– Strong database and caching experience.
– Experience with service-to-service APIs such as gRPC, REST, or similar.
– Ability to reason about reliability, idempotency, retries, failure modes, and operational
behavior.
– Strong communication skills and ability to work independently as a contractor.
Preferred Experience
– Experience with authorization, access control, rules engines, alerting, notifications,
workflow systems, or similar business domains.
– Experience with high-volume production systems.
– Experience improving observability, testing strategy, and rollout safety.
Ideal Candidate
The ideal candidate is a pragmatic senior engineer who can quickly understand an
existing system, identify useful refactoring opportunities, and make meaningful
improvements without disrupting production behavior.
