Job: Senior Software Engineer (Python/Django)
TR Ref: CLDB/TR13616
Location: Fully Remote but must be UK based.
Our client has a powerful, data-driven, AI/ML platform that's transforming the way businesses connect with their customers and partners. Enjoying stellar growth, they’re now on track double revenue in the next 12 months (again!), so this is a rare opportunity to join at such a critical inflection point.
We’re looking for a Senior Software Engineer who can own the full stack and who's capable of stepping into any part of the system, understanding it, improving it and ensuring business continuity. You will be joining a small, high-impact engineering team building the tech that powers their direct-to-consumer platform, mobile app and integrations.
You'll work across backend services, frontend applications, cloud infrastructure and third-party integrations. You will need to understand the why behind the system, rather than just working tickets. It's also a strategic role, as you will be contributing to technical direction.
What you will be responsible for:
Core Engineering
* Backend development in Python/Django - building and maintaining the API layer, business logic and data models
* Frontend contribution using Vue.js - working on their customer quote journey and internal tooling
* Database design and management with PostgreSQL - schema evolution, query performance, data integrity
* Async processing - working with their task/worker system for background operations (risk checks, payment processing, document generation)
Integrations & Partnerships
* Building and maintaining integrations with partners, including aggregators, risk data providers, payment processors and regulatory data sources
* Designing API endpoints for new partner onboarding
* Understanding and working with external APIs across quoting, credit/risk assessment, fraud detection, validation and communications
Infrastructure, Security & Production Health
* Owning the health and security of production systems - monitoring, troubleshooting, ensuring uptime and maintaining the security posture across their Linux-based infrastructure
* Managing and evolving their AWS infrastructure (EC2, RDS, S3, SES etc.)
* Contributing to their infrastructure-as-code migration (Pulumi)
* Supporting CI/CD pipelines and deployment processes
* Participating in system upgrades, inc. Python, Django, PostgreSQL and OS-level modernisation
Product Expansion
* Contributing to the development of new products as the company expands into adjacent markets
* Working with product and compliance stakeholders to translate business requirements into technical solutions
* Designing systems that are multi-product and multi-brand capable from the outset
Technical Leadership
* Becoming a full knowledge holder across the platform - backend, frontend, infrastructure, integrations and business logic
* Contributing to architectural decisions - codebase restructuring, reducing technical debt, deployment strategy
* Writing and maintaining technical documentation to ensure knowledge is shared and recoverable
* Mentoring and supporting other team members as the team grows
Tech stack: Python, Django, Linux/Unix, HTML/CSS/JS, SQL (PostgreSQL, MySQL), Vue.js, ORMs, RESTful APIs, AWS, Docker, Git and various third-party integrations (web and mobile).
What Tech Skills Are Needed:
* 5+ years hands-on Python development using Django, comfortable navigating and extending a large Django codebase
* PostgreSQL experience, inc. schema design, migrations and performance tuning
* Strong Linux/Unix skills - you live in the terminal and will be confident with SysAdmin, debugging production issues via SSH, reading logs, managing processes and understanding how a Linux server runs end to end
* AWS experience - you will have deployed and managed production workloads
* Docker - you use containers as part of your daily development and deployment workflow
* Security-conscious mindset - you understand application security fundamentals, data protection principles (GDPR, DPIAs), encryption at rest and in transit, and secure handling of PII. You think about security as part of everyday development, not as an afterthought
* API design and integration - you've built and consumed RESTful APIs, worked with third-party integrations and handled authentication flows
* Frontend competency ie you can work productively in a Vue.js (or similar modern JS framework) codebase. [You don't need to be a frontend specialist, but you can't be afraid of it]
* Version control - comfortable with Git workflows, branching strategies and working across multiple repositories
* Desirable skills include: Experience in a regulated industry where data protection compliance (GDPR, DPIA, ICO reporting) is part of daily work; Familiarity with Infrastructure-as-Code (Pulumi, Terraform, CloudFormation etc); Experience tackling technical debt (major version upgrades, codebase restructuring, improving test coverage and CI/CD in a production system); Configuration management (using SaltStack, Ansible or similar); Mobile app experience.
Other skills required:
* Effective remote worker. You know how to stay productive, communicate asynchronously, manage your own time and maintain visibility without being in an office
* Self-directed and autonomous - you can take a loosely defined problem, investigate, plan and deliver without constant supervision
* Business acumen - you understand that code serves a business. You can engage with commercial requirements, ask the right questions and make technical decisions that align with business goals, not just engineering preferences
* Project and workload management - you can juggle multiple priorities, estimate work realistically and keep things moving without someone managing your backlog for you
* Effective communicator. You can explain technical decisions clearly to both technical and non-technical stakeholders
Why Join?
* Base Salary of £70-80K along with generous Equity / Share Options offering real wealth creation potential.
* High impact. Your decisions and work will directly shape the future of the platform, company and potentially, an entire industry.
* Rapid Growth. They are scaling rapidly, so this is an exciting time to join
* Cutting-edge challenges inc AI/ML, working with large datasets, third-party integrations and scalable, high-performance architecture
* Flexible remote working with only occasional meetups
* Continuous learning – encouraged to experiment with new tech
