Software Developer

UpperPlain; Time; On-site; NOK 900,000 - 1,100,000; Full time

Job summary

UpperPlain in Norway is seeking a hands-on software engineer to build web apps, APIs, and data models that reflect how client teams work.

You will integrate CRMs, ERPs, payments and files through APIs and events, add screens for dispatch, quotes, job status, and reporting, and write tests while keeping changes small and reviewable.

Qualifications

• Experience shipping production software relied on by others.
• Hands-on across the stack: TS UI, a real backend, and a real DB.
• Familiar with using existing business systems as a user or integrator.
• Experience using AI coding tools with discipline: generate, then read, test, and simplify.
• Able to take an imperfect brief, ask the two questions that matter, and start building the first slice.

Responsibilities

• Build web applications, APIs, and data models aligned with client workflows.
• Connect to CRMs, ERPs, accounting, payments, files, and tools via APIs or events.
• Add missing screens: dispatch, quotes, job status, dealer catalogs, approvals, reporting.
• Write tests, handle auth and roles, and keep changes small enough to review and reverse.
• Ship behind the monthly request list: one useful improvement at a time on Build, more capacity on Growth and Scale.
• Support what you ship. Hosting and maintenance are part of the job, not a later team.

Job description

• Build web applications, APIs, and data models that match how the client’s team actually works.
• Connect to CRMs, ERPs, accounting, payments, files, and industry tools through APIs, events, or careful sync.
• Add the missing screens: dispatch, quotes, job status, dealer catalogs, approvals, and reporting.
• Write tests, handle auth and roles, and keep changes small enough to review and reverse.
• Ship behind the monthly request list: one useful improvement at a time on Build, more capacity on Growth and Scale.
• Support what you ship. Hosting and maintenance are part of the job, not a later team.

What you will do

• Build web applications, APIs, and data models that match how the client’s team actually works.
• Connect to CRMs, ERPs, accounting, payments, files, and industry tools through APIs, events, or careful sync.
• Add the missing screens: dispatch, quotes, job status, dealer catalogs, approvals, and reporting.
• Write tests, handle auth and roles, and keep changes small enough to review and reverse.
• Ship behind the monthly request list: one useful improvement at a time on Build, more capacity on Growth and Scale.
• Support what you ship. Hosting and maintenance are part of the job, not a later team.

What you bring

• Professional experience shipping production software that other people depend on.
• Hands-on work across the stack: TypeScript or similar on the interface, a real backend, and a real database.
• You have used existing business systems as a user or integrator, so you do not treat every problem as a new app.
• You already use AI coding tools with discipline: you generate, then you read, test, and simplify.
• You can take an imperfect brief, ask the two questions that matter, and start building the first slice.

AI-first, in practice

• AI is how you research APIs, sketch implementations, and catch mistakes. It is not how you avoid understanding the system.
• You can implement a model-backed feature: structured output, tool calls, retrieval, or a review queue.
• You care about latency, cost, and failure modes when a model is in the path of real work.
