Software Developer (Platform)

As a Software Developer (Platform) at HECOD Blockchain, you will write, test, and maintain the code behind HECOD Collect and the products that follow it. This is a hands-on engineering role on a small team where you own features end to end, from requirement through data model and API to tests, deployment, and documentation. Collect handles money-adjacent records, so the engineering standard is correctness first, clear audit history, and permissions enforced on the server.

What you'll do

• Write, modify, integrate, and test software code for web applications and backend services
• Maintain existing programs by making modifications as required, including bug fixes, refactoring, and performance improvements
• Identify and communicate technical problems, processes, and solutions to the founder and team
• Prepare reports, technical documentation, architecture notes, runbooks, and internal manuals
• Research and evaluate software products, libraries, frameworks, and services before adoption
• Assist in the design of database schemas and data migrations
• Participate in code reviews and maintain code quality standards
• Lead and coordinate small development tasks with other engineers when required
• Maintain and extend Collect's data model for invoices, customers, payments, credits, disputed amounts, and balances in each invoice's currency
• Build and test the rules engine that prioritizes follow-up by overdue age, balance, and follow-up history
• Implement hold logic that keeps paid, disputed, promised, snoozed, and stale records out of reminders
• Build scheduled reminder processing that respects workspace rules, approval requirements, and daily delivery limits
• Implement sending checks that stop a reminder when the underlying record has changed since the draft was approved
• Monitor and handle delivery failures, retries, and bounces
• Enforce role-based access (Owner, Administrator, Collector, Approver, Viewer) using PostgreSQL row-level security
• Keep company data isolated between workspaces
• Log every change and approval so a user can see who did what and when
• Maintain CSV import with validation, error reporting, and duplicate review
• Contribute to the upcoming QuickBooks Online integration, including authentication, sync logic, and reconciliation
• Build and document internal APIs used by the web application
• Write automated tests (unit, integration, and end-to-end) for all new work
• Deploy to production through the existing pipeline and verify releases after deployment
• Write short incident reports when something breaks, covering cause, impact, and fix
• Keep technical documentation current

What you bring

• A Bachelor's degree in computer science, software engineering, computer engineering, or a related field, or a college diploma in computer programming or software development
• 3+ years of professional software development experience
• Experience shipping and maintaining a production web application
• Strong TypeScript or JavaScript
• Strong SQL and experience with PostgreSQL or another relational database
• Experience designing, building, and testing APIs
• Experience with background jobs, scheduled tasks, or queues
• Working knowledge of Git, code review, and CI/CD pipelines
• Understanding of authentication, authorization, and secure handling of business data
• Clear written communication in English
• Ability to break an ambiguous requirement into small, testable pieces
• Comfort working directly with the founder and without layers of management

Nice to have

• Next.js and React
• Supabase, including row-level security policies
• Cloudflare Workers or other edge runtimes
• Stripe billing integration
• Experience with accounting, invoicing, billing, or receivables data
• Experience integrating with QuickBooks Online, Xero, or similar accounting APIs
