Location: Atomic is a remote company. For this position, it means that you can work remotely from any part of LATAM.

Key Responsibilities:

• Play a key role in designing, developing, and architecting our microservices and Temporal workflows behind money movement, trading, and account lifecycle. Long-running state machines with real financial consequences are critical. Determinism, replay safety, idempotency, and other “retryable” challenges will be important aspects in your work.

• We are a technology-first company, leveraging a cloud-native technology stack (Temporal, Kubernetes, Istio, AWS), AI and automation tools and agents for development and testing.

• You make architectural decisions across a variety of systems and raise the bar on how we test these systems that must be correct.

• Own gRPC services end-to-end in a multi-tenant platform along with partner-facing REST APIs.

• Tackle really tough engineering and product problems and operate what you build. Instrument services in Datadog; own traces, dashboards, and monitors in your area.

• Build and debug integrations with custodians, clearing systems, banking partners, and calculate and generate tax documents.

Qualifications:

We are looking for candidates who are creative, autonomous, curious, and rigorous. Some things that may make you a great fit:

• 8-10+ years of software development building and operating production backend systems

• Computer Science degree or equivalent experience

• Go, or deep experience in another statically typed language plus genuine enthusiasm for picking it up

• Experience working on distributed systems where partial failures are expected (idempotency, exactly-once semantics, and reconciling against external sources and internal data are problems you have dealt with

• Experience in successful delivery of high-quality production services and systems: you’ve debugged from traces and logs, created postmortem documents and runbooks

Nice to have:

• Prior experience in the financial industry and comfort in a regulated environment

• Direct experience with Temporal or similar workflow engines where determinism, versioning, building fault-tolerant workflows, and a real sense of what belongs in an activity versus the workflow itself

• Experience with Datadog or comparable observability tooling, including building the dashboards and monitors

• Familiarity with gRPC and protobuf at scale

• Exposure to brokerage domain concepts such as clearing, settlement, corporate actions, KYC/AML, books and records.
