About weframe

weframe builds custom AI/tech systems for business owners who know AI matters but haven't figured out where to start. We come from inside a fast-scaling tech company where we built AI systems that drove millions in revenue and replaced entire manual workflows. We know what works, what doesn't, and what it costs when nobody asks the right questions first.

Our delivery is hands-on and outcome-driven. We don't consult - we build. You'll be joining a small team where the quality of your work is visible immediately.

The Role

You'll embed directly into client engagements and build. Not scope and hand off, you will do the building. You'll report directly to our technical co-founder and work on live projects with real clients.

This is a contractor role. We care about what you can do today, not your trajectory. If your output is strong, there will be more work.

What You'll Do

• Embed with client teams to understand their workflows, systems, and real problems - not just their stated requirements
• Scope and build AI-powered solutions tailored to each client's specific context, data, and constraints
• Work hands-on across the stack: LLM integration, prompt engineering, evaluation pipelines, APIs, and data plumbing
• Make pragmatic architectural decisions that balance speed of delivery with maintainability
• Iterate based on client feedback - shipped software is the start of the work, not the end
• Monitor and maintain deployed systems post-launch; debug issues in client environments
• Work directly with the technical co-founder on delivery decisions

What We're Looking For

• Strong software engineering fundamentals - you write code that works and that others can follow
• Highly fluent with AI-assisted development: Claude Code, Cursor, Codex, or equivalent - you use these tools to ship faster without sacrificing quality
• Comfortable with ambiguity - you can walk into a messy problem without a spec and figure out what to build
• Experienced with LLM integration and prompt engineering in production environments, not just prototypes
• Strong communicator - you can explain a technical trade-off to a non-technical client without losing them
• Proactive in client settings - you ask the right questions early and dig below surface-level requests to find the real problem
• Security-aware - you treat compliance and secure-by-design as part of delivery, not an afterthought

How to Apply

Stage 1: CV + Send us something that shows us how you work. A GitHub profile or  a project you’ve shipped, and a short description of how leverage AI) 

Stage 2 - 20 min call with co-founder: Not a technical interview. A conversation. Give them a vague, real-ish client problem and listen for whether they ask good questions or jump to solutions.

Why This Role

You'll build systems that move real money and digital assets — exchanges, payment rails, crypto processing, and OTC desks — where every decision touches security, latency, and correctness. The

problems are real: real adversaries, real settlement guarantees, real users who can't afford downtime. If you want ownership over production fintech infrastructure rather than another CRUD app, this is that.

You'll join a small team shipping to production frequently, owning features end-to-end across our backend services, customer-facing products, and internal back-office tools.
 

Tech Stack

- Backend: Python 3.12, FastAPI, SQLAlchemy + Alembic, Gunicorn/Uvicorn

- Frontend: React 18 + TypeScript, Vite, Tailwind + shadcn/ui, React Query

- Back-office: React 18 + TypeScript, Vite, Tailwind + shadcn/ui

Databases: PostgreSQL 17 + MongoDB
 

What You'll Do

- Own full-stack features from spec through deployment, monitoring, and iteration

- Build and maintain FastAPI services handling payments, exchange, and crypto-processing flows

- Develop responsive interfaces for both customer-facing products and internal back-office tools

- Model and optimize data across PostgreSQL and MongoDB; manage migrations with Alembic

- Integrate third-party payment, banking, and crypto APIs

- Bake security and compliance into everything — you'll be trusted with money-handling code, often without a dedicated QA safety net
 

Must Have

- 5+ years full-stack experience, with at least 3 building production backend services

- Strong command of Python / FastAPI and React + TypeScript

- Solid experience with PostgreSQL (relational modeling, query optimization)

- Advanced, daily use of AI tools in your workflow — you use assistants like Claude, Copilot, or

- Cursor to scaffold, refactor, and review code, and you can judge when to trust their output and when

to discard it

- Genuine independence — you take ownership, make sound calls, and drive work forward with minimal oversight (essential on a remote, fast-moving team)
 

Bonus

- Experience with MongoDB and the wider frontend stack (Vite, shadcn/ui, React Query)

- Fintech background — payments, banking, PSP, or exchanges

- Crypto / digital assets — exchanges, processing, custody, or OTC (a strong extra plus)

About the Project

The company has built an online platform for peer review and independent publication of academic manuscripts. Authors upload their papers, go through a peer-review process, and readers gain access to the resulting review reports. The platform consists of two parts: a public and private portal for authors and reviewers (manuscript upload, payments, review workflows, and report generation) and an internal management panel used by the company's own staff.

The platform is approximately 90% complete, built by a previous vendor whose engagement ended due to significant delivery delays. The existing codebase contains bugs, deviations from the original specification, one missing critical component, and outdated dependencies. We are looking for a Lead Developer to take ownership of this codebase, stabilize it, complete the remaining work, and bring the platform to a reliable, commercially launchable state.

What You'll Do

You will play a leadership role within the customer's development process — not writing code yourself, but directing, validating, and de-risking delivery across the audit, stabilization, and completion phases.

• Audit the current system, architecture, and end-to-end workflows; document issues, gaps, and deviations from spec; produce a prioritized inventory that separates Go-Live-critical items from non-critical improvements.
• Lead the development team through stabilization and the remaining phases — setting priorities, defining work packages, and ensuring critical issues and the missing component are resolved.
• Validate the team's deliverables at a system level — confirming they meet agreed requirements, quality standards, and acceptance criteria before sign-off.
• Verify that core workflows run reliably end-to-end so the company can begin sales and onboard users smoothly.
• Surface technical risks early and advise on technical decisions and trade-offs.
• Contribute to requirements definition, scope, deliverables, and acceptance criteria — including technical input on MSAs/SOWs where relevant.
• Establish lightweight delivery processes and governance to keep progress transparent, controlled, and on track.

Tech Stack

• Frontend: Angular
• Backend: Node.js
• Database / Infrastructure: PostgreSQL on AWS; Nginx
• Source / Docs: GitHub
• Integrations: ~5 third-party services covering payments, plagiarism checking, reviewer matching, and document handling
• Scope: ~14 major functional modules (manuscript submission, peer-review management, reviewer matching and workflows, payment processing, PDF/report generation, publication of review outcomes, notifications, and admin/management functions)

What We're Looking For

Must-Have

• Senior, hands-on engineer with a track record of leading software products into production.
• Strong command of the stack: Angular, Node.js, PostgreSQL, and AWS (Nginx-based setups a plus).
• Demonstrated experience with legacy system takeovers, audits, and stabilization of inherited codebases — comfortable navigating unfamiliar, imperfect code and making it reliable.

Ready to build something meaningful?

Let’s talk. Your next big adventure might just start here.

If you do NOT want to disappear inside a large company doing small, invisible tasks for months – surrounded by people who don’t care, buried in bureaucracy, time tracking, and performance reviews that lead nowhere – this role may be for you.
 

If you DO want to work somewhere your contribution counts, where you can grow fast and work on real problems that actually matter – keep reading.
 

What the work actually looks like

• Design, deploy, and manage small applications end-to-end
• Ship internal and external tools
• Solve practical engineering problems — integrations, scripts, automations, backend logic

We care more about how you think than what you’ve already shipped.

You’ll likely fit this role if:

• You use AI tools naturally as part of how you work
• You scope problems before writing code — and know what to skip
• You notice details others miss
• You’re honest about what you don’t know, and quick to figure it out
• You’ve built something recently, even if it was small

What we don’t care about

• Your years of experience
• Whether you’ve worked at a well-known company
• A perfect CV

Stack

We use what fits the problem. You should be comfortable with JavaScript, basic deployment, and working directly with APIs and LLM-based tools.

Our hiring process

• Short assessment (~45 min)
• Interview with the founder
• If it clicks, we move fast

Short assessment

We use a testgorilla for our short assessment. No trick questions. No algorithm puzzles. Just practical scenarios that reflect what the job actually looks like.
