Intermediate Software Engineer - Onni Capital

Onni Capital is being designed as a high ownership, low bureaucracy team.

We work in small project groups, test ideas quickly, put early products in front of users, and make decisions based on evidence rather than hierarchy.

Team members are expected to:

Challenge assumptions and communicate directly

Take responsibility for outcomes, not simply produce recommendations

Use modern AI and development tools to work faster and produce better results

Share unfinished work early and improve it through feedback

Move comfortably between strategic analysis and hands on execution

Know when to continue investing in an idea and when to stop

Operate effectively without a detailed playbook

This is not a role for someone who wants months of consensus building, a rigid job description, or a narrowly defined set of responsibilities.

It is for someone who learns quickly, takes initiative, enjoys solving ambiguous problems, and wants to help build something from the ground up.

Strong proficiency in the modern TypeScript and React ecosystem, including Next.js, TypeScript, React, REST APIs, and relational databases. Bonus points for experience with Supabase and Postgres

Comfortable in Python for backend services and AI and agent tooling, using FastAPI or similar

Solid backend systems design and API development experience

Hands on experience with DevOps practices, including CI and CD pipelines, Docker, and containerisation

Regularly uses AI assisted development tools, specifically Claude Code, as a core part of your workflow, with the judgment to know when to trust output versus verify it

Practical experience integrating LLMs into production applications via provider APIs such as Anthropic, OpenAI, or OpenRouter, including prompt engineering, context management, streaming responses, tool and function calling, structured output, and evaluating output quality

Foundational understanding of application security, including authentication, authorisation, secrets management, and audit logging

Ability to work semi independently. You can pick up a problem, break it down, see it through to production, and know when to ask for help rather than spin

Strong interpersonal skills. You know how to work with people, communicate clearly, give and receive constructive feedback, and build trust on a team

A bias toward action and comfort making progress with incomplete information

Comfort working in a small, fast moving team where responsibilities change as projects develop

High personal standards for accuracy, quality, ownership, and follow throug

Experience with tools such as Claude, Claude Code, Codex, Cursor, Linear, Slack, Databricks, Microsoft Azure, or similar platforms

Experience with open source AI agent frameworks such as LangChain, CrewAI, or AutoGen

Experience with retrieval augmented generation (RAG) and vector databases

Infrastructure as code experience

Familiarity with real estate technology or property management platforms

Experience with data pipeline tools such as Databricks or Airflow

Background in regulated industries with strict audit and compliance requirements

Experience with React Native or cross platform mobile development

Experience with Twilio or voice and telephony APIs

Previous founder, side project, or entrepreneurial experience

You will see the full lifecycle of a product rather than one narrow piece of it.

On a single product, you may be involved in:

Sitting in on the user interviews that define the problem

Shaping the architecture and data model from the start

Building and shipping the first working version

Deploying it into an operating business and watching real users hit it

Instrumenting it so that impact can actually be measured

Hardening a validated prototype into a production system

Presenting the build directly to senior executives

Deciding, with the team, whether it is worth continuing to invest in

The expectation is high ownership. You will be accountable for what you ship and how it behaves in production.

Salary Range:

$90,000 - $120,000 Per Year
