About the role
You’ll build the middleware connecting Salmon’s ATM fleet to backend systems, as we scale from a pilot network to thousands of machines across the Philippines.
What you’ll do
- Work on real‑time transaction flows between ATM hardware and Salmon’s backend, handling authorization, reversals, and reconciliation as the fleet scales.
- Integrate directly with an HSM for PIN translation, key management, and cryptographic operations — core to how every transaction stays secure.
- Work closely with hardware, infrastructure, security, compliance, and vendor teams (SmartDico, the processing switch) to keep the ATM stack running end to end.
What you’ll own
- Design, build, and maintain backend services for the ATM middleware platform.
- Own ISO 8583 message flows between the ATM fleet and the processing switch, including authorization, reversals, and reconciliation.
- Integrate with the HSM for PIN translation, key management, and cryptographic operations.
- Build and maintain integrations with card schemes and the ATM middleware vendor.
- Improve APIs and system integrations across the ATM stack, including anti‑fraud and core banking connections.
- Support production monitoring, incident investigation, and resolution for ATM transaction services.
What makes you a strong fit
- 3+ years of experience as a Software/Backend Engineer, ideally in fintech, banking, or payment processing.
- Experience with microservice architecture, API design, and building system integrations from scratch.
- Knowledge of ISO 8583 or similar financial messaging protocols.
- Experience with cloud infrastructure (AWS/EKS), containerized deployments, and GitLab/GitOps CI/CD pipelines.
- Strong SQL skills for data analysis and validation.
- English level B2 or higher, with strong written and verbal communication.
What we offer
- Ownership and flexibility.
- Stock option plan — four‑year vesting with a 25% cliff after the first year.
- Fully remote work with core collaboration hours from 12:00 to 6:00 PM Manila time (UTC+8).
- Company‑provided tools and equipment.
- Health and time off.
- Medical insurance support for you and your family through co‑funding or reimbursement, depending on your location and subject to policy limits.
- Access to an internal mental health support specialist.
- 22 vacation days, Philippine public holidays, and 15 sick days.
- Opportunities to learn and share your expertise through internal expert meetups, external conferences, speaking opportunities, and industry publications.
- Company‑sponsored trips to Manila to meet and work with your team in person.
