Senior full-stack product engineering
A job description rarely describes the real risk in a product. It helps to work with someone who has already built something similar.
Discovery stays short and specific: users, data, and risks. After that we build the critical path first and strengthen it from there.
If that sounds like your situation, Arcode is set up for companies hiring a proven software engineer. End-to-end ownership across React/Next.js, NestJS, databases, and cloud.
What you get
- Scalable web applications
- Clean architecture and APIs
- Performance and accessibility
- Remote-ready collaboration
- One studio accountable for the result
- Design and engineering on the same schedule
- Support available after launch
How engagement works
As your software engineer, we run a shared backlog, design reviews, and engineering sprints, and you keep one point of contact throughout.
- 01
Discover
Goals, constraints, data sources, and success metrics, all settled before we touch architecture or prompts. The work for teams in London stays tied to the outcome you asked for.
- 02
Design
System design, AI/tool boundaries, interface direction, and interaction prototypes. You see progress on the critical path every week.
- 03
Build
Modern stack, clean architecture, evaluated AI behavior, and iterative demos you can react to. Nothing here waits on a handover between separate teams.
- 04
Launch
Ship, monitor, harden, and keep improving models, tools, and product after go-live. On software engineering projects we favour practical architecture over trendy defaults.
How we build it, and why
The stack is chosen per project, not applied from a template. For software engineer work these are the defaults, and the reason each one is on the list.
- TypeScript
- types across the whole stack, which catches the class of bug that only shows up in production
- Next.js
- server rendering and static generation in one framework, so marketing pages stay fast and app routes stay dynamic
- NestJS
- structure and dependency injection on the backend, which keeps a growing API from turning into a pile of route handlers
- PostgreSQL
- relational integrity for data you cannot afford to get wrong
- AWS
- the services you grow into, once a managed platform stops being enough
What the first weeks look like
- Days 1-3
Context and constraints
Codebase, deploy path, and what "done" means for the software engineering. Short, because the useful version of this is specific.
- Week 1
First shipped slice
Something real goes out in the first week — scalable web applications rather than a setup ticket.
- Weeks 2-6
Build to the milestone
Pull requests, reviews, and weekly demos. You see the work as it happens rather than at a handover meeting.
- Handover
Documented and transferable
Runbooks, architecture notes, and a walkthrough, so the work does not depend on us still being here.
Weighing up your options
There are three realistic ways to get this built. Each is the right answer for someone.
A solo freelancer
Cheapest per hour and fine for a contained task. The risk on software engineering is breadth — one person covering design, backend, infrastructure, and launch usually means one of them is weak, and there is no cover when they are unavailable.
A local agency in London
Same timezone and a face to meet, which genuinely matters for some teams. You are also paying London market for SaaS, fintech, and AI product talent. rates for the whole team including the layers that never touch your software engineering, and a local shortlist is a small shortlist.
Arcode
A small senior team. The people who scope the software engineering write the code, you get weekly demos instead of status decks, and the engagement ends when the thing is live and handed over.

Working with teams in London
London market for SaaS, fintech, and AI product talent. We work with clients in London remotely and keep overlapping hours in GMT/BST. We usually collaborate in English.
How we work with London teams
London is on GMT/BST, which gives us an overlapping working day rather than a handful of shared hours. Standups, reviews, and demos all fit in normal business hours for both sides.
What London clients usually need
London work is heavily SaaS and fintech: dashboards over real financial data, onboarding and KYC flows, and increasingly LLM features layered onto products that already have paying users.
Contracts, data, and compliance
Procurement in London tends to ask for a DPA, evidence of where data sits, and a security questionnaire before signing. We handle those upfront, and we keep personal data in UK or EU regions by default.
