What You’ll Do
As a Senior Product Engineer at Oneiro, you will sit at the intersection of product, engineering, and customer delivery.
You will design, build, and ship high-quality features, workflows, and integrations that help financial institutions operate on DLX with confidence.
This is a senior individual contributor role for an engineer who can take meaningful ownership of product work from discovery through design, implementation, launch, and production follow-up.
You will work closely with Product, Design, Engineering, and client-facing teams to understand real customer problems, translate them into pragmatic technical solutions, and deliver software that is reliable, maintainable, and valuable.
You will not be expected to operate at Staff Engineer scope, setting company-wide technical strategy or owning multiple domains. However, you will be expected to act as an anchor for project delivery: identifying risks early, improving the systems you work in, mentoring less experienced engineers, and raising the quality bar within your team.
* Own product work end to end – Take meaningful features, workflows, and integrations from problem definition through design, implementation, release, and production follow-up.
* Build high-quality software – Write clean, maintainable, well‑tested code across the stack, with strong attention to reliability, performance, security, and financial correctness.
* Turn ambiguity into delivery – Break complex or unclear problems into clear technical plans, identify risks early, and keep projects moving without unnecessary process.
* Work closely with Product, Engineering, and customers – Understand real user needs, challenge assumptions constructively, and translate business problems into pragmatic technical solutions.
* Develop deep domain expertise – Become fluent in syndicated lending, loan administration, and the workflows DLX supports, using that knowledge to build better products.
* Raise the engineering bar – Contribute thoughtful design discussions and code reviews, improve the systems you touch, and mentor junior and mid‑level engineers.
* Improve how the team works – Spot repeated friction in tooling, documentation, testing, or delivery, and help make the team faster and more effective.
Requirements
We would expect you to have:
* A degree in Computer Science, Mathematics, Engineering, another STEM field, or equivalent practical experience.
* 5+ years of professional software development experience.
* Strong experience building and operating production software systems.
* Strong expertise in TypeScript, JavaScript, Python, Java, or similar production languages.
* Practical experience using AI development tools to improve engineering productivity, code quality, testing, debugging, documentation, or delivery speed.
* Experience owning features or workstreams end to end, from requirements through deployment and support.
* Ability to write clean, maintainable, well‑tested code.
* Good understanding of system design, data flows, API design, reliability, performance, and security.
* Experience with cloud‑native architectures, distributed systems, APIs, integrations, or workflow‑driven systems.
* Experience with automated testing, including unit, integration, or end‑to‑end testing.
* Strong communication skills with engineers, product managers, business stakeholders, and customers.
* Comfort operating in a fast‑moving startup environment where priorities can change and ambiguity is part of the job.
* A product‑minded approach and a desire to build deep domain expertise.
Experience in fintech, banking, corporate lending, capital markets, payments, or another complex regulated domain is highly valuable, but not required.
Nice to Have
* Experience building software for financial institutions or regulated environments.
* Familiarity with corporate banking, syndicated loans, loan servicing, or financial operations.
* Experience integrating with third‑party systems, APIs, or enterprise platforms.
* Experience working in SOC 2, ISO 27001, GDPR, or similarly controlled environments.
* Previous startup or scale‑up experience.
* Experience mentoring junior or mid‑level engineers.
