IT Junior Python Developer Role

Role Overview

As an IT Junior Python Developer, you'll support the backend infrastructure powering B2C2's trading engines. Day-to-day involves coding features that enhance trade execution speed and reliability, directly impacting client profitability in volatile crypto markets.

Detailed Responsibilities

• Develop and test Python scripts for data processing from market feeds like CoinAPI or internal streams.
• Optimize algorithms for low-latency order matching using libraries like NumPy and Pandas.
• Collaborate on RESTful APIs with FastAPI to integrate trading dashboards for quants.
• Debug production issues in Dockerized environments, ensuring 99.99% uptime during peak trading hours.
• Contribute to CI/CD pipelines with GitHub Actions, automating deployments for new liquidity pairs.
• Analyze trade logs with SQL queries on PostgreSQL to identify performance bottlenecks.

Day-to-Day Workflow

Mornings kick off with stand-ups via Slack or Zoom, reviewing overnight market events and sprint priorities. You'll spend mid-morning coding in VS Code, paired with a senior dev on features like slippage reducers. Afternoons involve code reviews, testing in Jupyter notebooks, and demos to stakeholders before EOD wrap-ups.

Remote setup means flexible hours aligned to London markets, with async updates keeping everyone synced.

Tools and Technologies

The stack centers on Python 3.10+ with asyncio for concurrency, alongside Redis for caching trade data. You'll use Kubernetes for orchestration, Prometheus for monitoring, and ELK stack for logs. Familiarity with WebSockets for real-time feeds and pytest for TDD rounds out the toolkit.

Skills and Requirements

Technical Skills

• Proficiency in Python fundamentals: OOP, decorators, generators, and async programming.
• Experience with data libraries: Pandas, NumPy, SciPy for quantitative analysis.
• SQL/NoSQL querying; bonus for time-series databases like InfluxDB.
• API development with Flask/FastAPI; understanding REST and WebSockets.
• Version control with Git; containerization via Docker.
• Basic fintech knowledge: order books, latency optimization, crypto protocols.

Soft Skills

B2C2 values quick learners who communicate code decisions clearly in PRs and meetings. Teamwork shines in pair-programming sessions, while problem-solving under time pressure mirrors live trading fixes. Adaptability to market shifts and curiosity about blockchain keep you ahead.

Experience Expectations

No prior internships required, but showcase 2-3 personal projects like a crypto trading bot on GitHub. A GPA above 3.4 in CS or related fields helps, paired with coursework in algorithms or data structures. Open-source contributions or hackathon wins signal initiative.

Salary and Benefits

For the upcoming season's remote internship, expect a stipend of $28-$35 per hour, translating to $5,500-$7,000 monthly for full-time equivalents. Full-time juniors post-internship start at $85,000-$110,000 base, plus performance bonuses up to 20%.

Perks include a $1,000 learning budget for Udemy or conferences, full remote setup with ergonomic reimbursements, and unlimited PTO. Health benefits cover telehealth, and many interns convert to full-time with relocation support if desired.

B2C2 Hiring Process

Step-by-Step Hiring Stages

1. Application: Submit resume and cover letter via B2C2's careers page.
2. Screening: HR phone call (15 mins) plus ATS filter on Python keywords.
3. Assignment: 4-hour take-home coding challenge on LeetCode-style problems.
4. Interviews: Technical (1hr with engineer), behavioral (45 mins with manager), live pair-coding.
5. Offer: Final call with negotiation; start within 4 weeks.

Application Timeline

Applications open now for summer/fall 2026 slots; aim to apply by May 15 for priority. Process spans 3-5 weeks, with offers rolling out weekly. Late apps considered if spots remain.

Screening Methods

ATS scans for "Python", "fintech", "algorithms"; tailor your resume accordingly. Portfolios with GitHub links get fast-tracked—include READMEs explaining trade sims. Referrals via LinkedIn boost visibility by 40%.

Interview Preparation

Example Interview Questions

• "Build a Python function to match buy/sell orders from a list, minimizing unmatched volume."
• "Explain how you'd handle race conditions in a high-frequency trading script."
• "Walk us through optimizing a Pandas DataFrame for 1M rows of tick data."
• "Describe a project where you debugged a production API failure."

How to Answer

Use the STAR method: Situation, Task, Action, Result. For technicals, think aloud—pseudocode first, then optimize. Practice on Pramp or Interviewing.io, timing responses under 5 minutes. Reference B2C2's low-latency focus to show research.

What Recruiters Evaluate

They prioritize clean, efficient code over perfection; 70% weight on problem-solving speed. Cultural fit via enthusiasm for crypto and teamwork examples. Bonus for domain curiosity, like explaining MEV in Ethereum.

How to Get Selected

Practical Tips

• Customize your cover letter with B2C2's recent volume milestones from their blog.
• Build a mini-project: Python bot simulating OTC trades, host on GitHub.
• Network on LinkedIn—message alumni with "Inspired by your B2C2 Python work."
• Prep system design: Scale a trading API to 10k TPS.
• Apply early; follow up politely after 10 days.

Common Mistakes to Avoid

• Generic resumes lacking Python project links—recruiters skip 80%.
• Ignoring async Python in challenges; it tanks latency scores.
• Overlooking behavioral prep; "tell me about a team conflict" trips many.
• Missing deadlines on take-homes; incomplete subs auto-reject.

How to Stand Out

Submit a video demo of your trading bot integrating real-time Binance data. Attend B2C2 webinars or crypto meetups for insider chit-chat. Tailor PRs in your portfolio to fintech pain points like slippage. Secure a referral—it's the golden ticket for junior roles.
