Who We're Looking For

Someone who doesn't just write code but understands business processes — able to take a real customer problem (inventory sync, complex checkout, ERP integration, business automation) and turn it into a stable, smart, maintainable solution.

Bonus if you've already built: SaaS systems, CRM systems, complex automations, Shopify Apps, Shopify Functions, system integrations, AI tools, ERP sync systems, backend infrastructure for business systems.
 

Soft Skills

Systems thinking and architectural planning ability, full end-to-end ownership of tasks, strong independent learning ability, proactive problem-solving, good communication with technical and non-technical teams, ability to work in a dynamic environment, willingness to work with AI tools like Cursor, Claude Code, or Codex as part of the dev process.
 

What You'll Build

From day one you'll work on systems in real use by leading eCommerce brands: Shopify Apps and Shopify Functions, subscription and billing systems, ERP and payment integrations, backend infrastructure for business systems, AI tools for automation and data analysis, sync engines and catalog enrichment.

Role: Power Platform Developer

Tech stack: Microsoft Power Platform + Microsoft 365

Salary range: $2.5k - $3k/mo

Location: Remote

----

An early-stage IT consultancy is looking for an experienced Power Platform developer to join our team delivering software solutions.

You'll act as a trusted technical partner to non-technical business stakeholders, turning their challenges into automated workflows, user-friendly interfaces, and well-modelled data stores.

This is a client-facing role, so we're looking for someone with strong communication and business analysis skills alongside solid technical ability.

You'll work closely with the solution architect to understand business needs and bring the solution to life.

If you enjoy solving real business problems and want to interact with the people who use your work, we'd love to meet you.

🔹 Company

We're an IT consulting company specialising in delivering software solutions on the Power Platform and Microsoft 365 technology ecosystem.

Our clients are traditional businesses without technical teams who have a business problem to solve where software is a great solution, but they lack the technical expertise to solve it.

We're a technical partner for them, helping them bring their vision of the software solution to life and deliver business impact.

The company is in its infancy, led by a solo founder, looking for a first developer to join the team.

🔹 Tech Stack

Technologies you'll work with:

Microsoft Power Platform (Power Apps, Power Automate, Copilot Studio)

Microsoft 365 Suite (SharePoint, Excel, OneDrive, Outlook)

Azure Cloud Platform: Azure Functions, Azure Static Web Apps, AI Foundry

Custom Code: TypeScript/Node.js, C#, PHP

While that's core, your work won't be limited to this stack, and you'll step outside it when needed. 

🔹 Responsibilities

1. Collaborate with stakeholders to gather requirements, refine solutions, and align with business goals.
2. Contribute to overall solution architectures.
3. Develop and implement Power Automate flows, transforming complex business logic into efficient solutions.
4. Design and build SharePoint-based databases.
5. Design and develop Canvas and Model-driven Power Apps to meet client needs.
6. Troubleshoot problems and provide support to existing solutions.

🔹 Required skills and experience

This is a client-facing role that solves problems that require real technical depth. So we're looking for someone who is deeply technical and has strong communication skills.

Technical skills

• Low-code development with Power Platform (Power Automate, Power Apps)
• Pro-code development with TypeScript/Node.js, C#, or similar languages
• Data modelling and database design
• Fluent in API integrations
• Comfortable working with unfamiliar technologies

Communication skills

• Upper-intermediate/advanced English
• Clear and concise communication
• Able to elicit requirements and manage expectations
• Able to express yourself well in writing
• Comfortable communicating using Loom videos

🔹 Hiring process

1. Intro interview
2. Tech interview
3. Final interview
4. Offer stage

🔹 What we offer

• Competitive compensation based on your skills & experience
• 18 days of paid time off + 11 local national holidays every year
• Independence and support to do your best work
• Sponsorship of professional certifications
• Small & friendly team, bureaucracy-free workplace, and processes
• Work where you want, remotely

No office traps.

We don't offer things like football tables, catered meals in the office, and other "perks" designed to keep you at work for all of your waking hours.

We want you to put in 8 quality hours, then go live your life, rest, and recharge so you can come back fresh to do it again.

About the role

We are building a fintech portfolio platform (encrypted client-side data, market data integrations, bank statement import) and a growing set of supporting services.
 

Our current delivery bottleneck is the Agentic Delivery Platform (coding layer): a production system where product managers and engineers drive feature work through AI agents - from clarification and prototyping to multi-agent development, preview environments, quality gates, and PRs.

This is not a chatbot wrapper. It is a stateful agent runtime: orchestration, sandboxed worktrees, Docker preview stacks, streaming UI, model routing, interrupt/resume, and human-in-the-loop controls. When this layer is unreliable, product velocity stalls. Making it production-grade is the priority of this role.

What you will own

Primary (blocker)

• Design and harden the agent delivery runtime (sessions, locks, work-state SSOT, recovery after restarts)
• Evolve the multi-agent pipeline: plan → audit → challenge → execute → test/code review → gates → commit
• Own preview lifecycle: lazy per-session stacks, idle suspend/wake, compile repair, publication gates
• Improve agent protocols: structured tools, prompt policies, read-only vs write modes, iteration loops
• Operate the coding-layer production path: deploy, isolated agent runtime, preview isolation, reliability
• Model routing: presets, per-agent model roster, allowlists, cost/latency/quality trade-offs

Secondary (ecosystem)

• Contribute across a multi-repo stack when needed: main web app (React/GraphQL), Python microservices (LLM parsing, market/FX data), shared libraries
• Keep cross-service contracts stable while agents and humans ship changes safely

Domain

• Portfolio / wealth-tech product surfaces
• Client-side encryption constraints (server never sees plaintext sensitive data)
• Market data and statement-import workflows
• Internal AI-assisted delivery tooling used as the main path to ship product work

Requirements

Must-have

• Strong TypeScript across Node and React
• Solid Docker experience (Compose, networking, volumes, prod vs local)
• Experience building stateful backend systems (sessions, locks, idempotency, restart recovery)
• Hands-on work with LLM/agent systems (tool calling, custom orchestrators, agent CLIs, or similar)
• Comfort designing contracts and SSOT (APIs, SSE/events, persisted state) instead of brittle chat heuristics
• Ability to work across multiple services/repos, not only one application package
   

Strong plus

• Multi-agent orchestration (planner/executor/reviewer patterns), evals, tool-use reliability
• Git worktrees / sandboxed agent runtimes / preview-in-the-loop workflows
• Python services (FastAPI or similar)
• Production ops: CI/CD, reverse proxies, separate app image vs agent runtime
• Interest in current agentic engineering: model routing, AI-native DX, human-in-the-loop systems, failure taxonomy
   

Nice to have

• GraphQL + MongoDB
• Applied crypto awareness (RSA/AES, client-side encryption constraints)
• Fintech or market-data experience
• Observability for agent pipelines (structured logs, step telemetry)

What success looks like

• The Agentic Delivery Platform stops being the delivery blocker
• Preview and agent runs are predictable under failure (interrupt, orphan processes, flaky builds)
• PMs/engineers can go from intent → reviewable preview/PR with clear gates and recoverable errors
• Multi-agent workflows improve iteratively without collapsing into prompt spaghetti
