SDE III - Software Engineer III - Backend/AI Agentic/AI Native at PortOne · Remote only · 4 - 6 years · Raised funding · Remote only · Posted 1 Nov 2026

About PortOne
PortOne is building the reconciliation and data intelligence layer for payments across Korea and international markets. We are a Series B startup backed by Softbank and Hanwa Capital, powering multi-billion dollars in annualised settlement volume for 2,000+ merchants across Korea, Thailand, Singapore, Indonesia, and beyond.
We are building AI-native products for leading brands — intelligent automation layers on top of complex financial data pipelines. If you want to work at the intersection of fintech, data engineering, and applied AI, this is your role.
Culture and Values
* You will be joining a team that stands for making a difference.
* You will be joining a culture that identifies more with Sports Teams rather than a 9 to 5 workplace.
* Your will have peers who are/have
** Highly Self Driven with A sense of purpose
** High Energy Levels - Building stuff is your sport
** Ownership - Solve customer problems end to end - Customer is your Boss
** Hunger to learn - Highly motivated to keep developing new tech skill sets
Your Work Ethic
* You are an athlete and building apps is your sport.
* Your passion drives you to learn and build stuff and not because your manager tells you to.
* You obsess over correctness — a bug in a settlement figure or a silent data drop is not acceptable to you.
* You have an eye for detail that most engineers skip past, and you take pride in getting it exactly right.
* Your work ethic is that of an athlete preparing for your next marathon. Your sport drives you and you like being in the zone.
* You are NOT a clockwatcher renting out your time, and NOT have an attitude of "I will do only what is asked for"
What will you do?
- Build and maintain financial data ingestion pipelines that pull settlement and transaction data from marketplace platforms (Amazon, Shopee, TikTok, Qoo10, Rakuten) on behalf of large brands operating across multiple Asian markets.
- Own reconciliation workflows end-to-end — from raw marketplace data to verified, merchant-ready settlement reports — ensuring every figure is correct and every discrepancy is surfaced, not swallowed.
- Design and implement AI-native features that automate financial analysis: agentic triage of settlement mismatches, root-cause detection across large transaction volumes, and intelligent alerting for ops and merchant teams.
- Instrument data quality and health monitoring so that silent failures — missing records, schema shifts, delayed ingestion — are caught before they reach the merchant.
- Build APIs and tooling that enable PortOne's ops and merchant success teams to investigate, verify, and close financial discrepancies faster and with more confidence.
- Expand platform coverage by integrating new marketplaces and new report types, working closely with data formats that are often inconsistent, undocumented, or changing without notice.
- Uphold rigorous engineering standards — correctness in financial data is not negotiable, and you treat edge cases and off-by-one errors with the same seriousness as a production incident.
- Uphold high engineering standards across codebases and processes.
- Collaborate with product, design, infrastructure, and operations stakeholders.
Skills and Experience
* Have ideally 4 to 6 Years of experience shipping high quality products/live features and workflows
*AI-native development — you build products where AI is a first-class component, not a bolt-on.
* Strong backend engineering foundation — Go (Preferred), Python, or equivalent; REST/gRPC APIs; database design.
* Understands how to build scalable, resilient, and observable distributed systems.
* Must have built data flows and applications end to end taking full ownership
Preferred Skills and Background
*Prior experience/built apps in golang backend
*Data and data engineering background — comfortable with data pipelines, ETL/ELT patterns, event-driven architectures, reconciliation logic, or analytical workloads.
*AI agentic development — experience building or working with agent frameworks, tool-use patterns, LLM orchestration, or automated reasoning pipelines.
