Product Engineer — Fintech Onsite CA– View

Sweet Tech builds financial applications on SweetOS, our platform of shared capabilities. We are looking for a Product Engineer to turn important business capabilities into dependable products that can be reused across customer deployments and developed as products in their own right.

You will work through Sweet Tech’s autonomous agentic development systems. These systems carry out implementation; your primary responsibility is to define intent, understand the application architecture, direct the agents, and validate the result rather than write application code directly.

SweetOS provides reusable building blocks for assembling applications repeatedly. A capability developed for one application can be made available to other applications through shared components and well-defined interfaces. You will learn how those building blocks fit together, how applications use shared capabilities, and where a change belongs so it can benefit more than one product.

This requires strong engineering judgment: break down requirements, specify behavior and constraints, understand data flows and permissions, review agent-generated changes, and verify correctness, security, and production readiness. You remain accountable for the outcome even when the systems perform the coding.

Sweet Tech has its own Software Development Life Cycle (SDLC) and Agentic Development Life Cycle. You will learn and follow these internal processes when defining work, directing autonomous agents, validating results, and delivering changes. Understanding our architecture and working within these development life cycles are core responsibilities of the role.

You will combine architectural and engineering judgment with deep ownership of a product domain, directing autonomous systems to perform implementation. Working with product stakeholders, customer‑facing engineers, and platform engineers, you will define how a capability should behave, guide its agent‑driven implementation, and improve it through real usage. Our product areas include digital signing, decisioning and workflow logic, and core financial capabilities.

• Translate business concepts into clear domain models, rules, state transitions, APIs, and usable product experiences.
• Specify and direct autonomous agents to build and evolve reusable capabilities across products such as Sweet Sign, Sweet Logic, and Sweet Core, with a defined ownership area.
• Own correctness: specify in variants, edge cases, validation, audit trails, and failure behavior; turn them into meaningful automated tests.
• Orchestrate delivery of full-stack capabilities, from the interface and user workflow to services, persistence, and integration contracts, so other applications can reuse them.
• Work with forward deployed engineers to distinguish recurring product needs from customer‑specific extensions and design appropriate reuse.
• Maintain versioned contracts, migration paths, documentation, and examples so other teams can adopt the product confidently.
• Use customer feedback and operational evidence to prioritize improvements, remove friction, and resolve production issues.
• Partner with platform engineers on identity, permissions, deployment, and observability while retaining ownership of the domain behavior.

• Experience building and maintaining production software across frontend and backend components.
• Strong data modeling and API design skills, with attention to business rules, consistency, and maintainable boundaries.
• Ability to learn a complex domain, ask precise questions, and explain how requirements translate into software behavior.
• Practical experience testing edge cases, diagnosing production…
