Job description

You will integrate our platform into the systems of prop firms, funds and trading desks through short, mostly remote engagements, and bring recurring client needs to the product team.

Solo Clash is a proprietary trading company with a simple mission: give aspiring traders the training, technology, and community they need to succeed, and let them focus on what they do best. We provide the environment; our traders bring the curiosity. Together, we win.

At the heart of our platform is our in-house analytics and trading engine, built to process real-time data and surface transparent statistics that help traders make better decisions.

What you'll do

• Lead short technical onboarding projects for new clients, working with their developers, risk managers and heads of trading, until the integration runs in production.
• Join pre-sales calls with the commercial team to scope pilots and answer technical questions.
• Build integrations and data pipelines between our APIs and client dashboards, risk systems, alerting and trading tools.
• Build prototypes of custom views, reports and workflows for client pilots.
• Identify the underlying problem behind each client request before writing new code.
• Debug and fix client-side production issues.
• Complete technical questionnaires and security reviews, and write integration guides and code samples.
• Identify custom work that repeats across clients and propose it as product features.

What we're looking for

• Junior: professional software engineering experience or a portfolio of shipped projects.
• Mid: experience that includes client-facing or cross-team work.
• Production experience with Python and/or TypeScript.
• Experience building and integrating REST and WebSocket APIs, webhooks and authentication (API keys, OAuth).
• Good SQL and data modelling skills.
• Experience with a cloud platform (preferably AWS), Docker, Git and CI/CD.
• You can explain technical trade-offs to clients in plain language, and tell them when the product is not the right fit.
• You take responsibility for your work and can make decisions when requirements are unclear.
• Good English and willingness to travel occasionally to London or client sites.

Nice to have

• Experience with trading or market data technology (FIX, Rithmic, TradingView webhooks).
• Background in fintech, data products, solutions engineering or technical consulting.
• Experience with Claude Code or other AI development tools, and building with LLMs.
• Knowledge of Next.js or React for client-facing interfaces.
• Familiarity with SSO, security reviews and compliance requirements at financial institutions.

What we offer

• Compensation based on experience.
• Access to Claude Code and other AI tools.
• Mentoring matched to your experience level.
• Responsibility for your own area of the product.
• Career progression based on performance.
