Note: The job is a remote job and is open to candidates in USA. Albo is a leading fintech company offering financial products to individuals and SMBs with the mission to bring financial freedom to everyone everywhere. As a Senior Backend Engineer, you'll design, build, and operate the microservices that power albo's core financial products while collaborating with cross-functional teams to ensure reliable financial infrastructure.
Responsibilities
- Design, build, and maintain backend microservices in Go and Java/Quarkus within our domain-oriented architecture (customer, account, transactional, and shared domains)
- Own services end-to-end: architecture, implementation, testing, deployment to QA/SBX/PROD, monitoring, and on-call ownership of what you ship
- Build event-driven and REST integrations across services (Pub/Sub, service-to-service REST via our private-proxy mesh), with strong guarantees around idempotency, reconciliation, and failure handling (dead-letter/reprocess, no silent data loss)
- Model and evolve data across MongoDB and SingleStore/MemSQL, keeping dual-write flows consistent between the display source of truth and what card authorization actually validates
- Ship through our CI/CD (Jenkins shared pipelines, containerized deploys to GKE/Kubernetes on GCP), managing configuration and secrets via GCP Secret Manager
- Write clean, self-documenting, well-tested code; participate in code reviews and raise the engineering bar for correctness and simplicity
- Collaborate cross-functionally with Product, Infra/Platform, and other backend squads to break down epics into shippable, incremental deliveries
- Instrument observability (structured logging, metrics, tracing) and use it to debug production issues and continuously improve reliability and performance
- Contribute to technical design docs, architecture diagrams, and shared conventions/scaffolding that scale the team
Skills
- Bachelor's degree in Computer Science, Software Engineering, or related field (or equivalent hands-on experience)
- +5 years of experience building and operating backend services in production, ideally in the Banking or Fintech industry
- Strong proficiency in at least one of Go or Java (Quarkus/Spring or similar), and willingness to work across both in a polyglot environment
- Solid experience with microservices and distributed systems: REST APIs, asynchronous/event-driven messaging (Pub/Sub, Kafka, or similar), service boundaries, and versioned contracts
- Hands-on experience with cloud infrastructure (GCP preferred), containers and Kubernetes, and CI/CD pipelines
- Comfort with both SQL and NoSQL data stores (MongoDB, SingleStore/MySQL/Postgres) and an eye for data consistency in money-critical flows
- Deep understanding of reliability patterns — idempotency, retries, reconciliation, graceful degradation — and why they matter when handling real money
- Customer Centricity: You're customer-obsessed, constantly thinking about improving the customer experience
- Hands-on: We're looking for a comfortable and willing leader to be a hands-on contributor who is energized by rolling up their sleeves, making things happen, and enabling the team to do the same
- Done is better than perfect: As things change and move quickly, you are excited by the fast pace and opportunity to constantly learn and help your team learn
- Communication: Excellent ability to communicate internally and externally, quickly build relationships, and work cross-functionally
- Extreme ownership: You hold yourself accountable to a high bar. You are supremely organized and see what needs to happen to achieve goals
- Results & Data Driven: You understand the business metrics you are responsible for, and you demonstrate these insights to drive constant improvement
- Familiarity with fintech/payments concepts (card authorization, ledgers, transfers, credit) is a strong plus
