Jobs Python

Numerical Technologies LTD is a leading provider of custom software solutions and services specializing in risk, limits, and regulatory capital systems. We are currently looking for a Senior Python Developer to join our team.

Project: Development of a Market Risk platform for a global financial institution, supporting risk analytics, market data processing, and large-scale financial applications. 

What will you be doing?
You will design and build risk calculations for Hypothetical P&L, Risk-Theoretical P&L, and Historical VaR — owning the full HVaR pipeline end-to-end, and architecting calculation components for the upcoming Expected Shortfall extension. Along the way, you will optimise compute-intensive batch and intraday workloads, own quality through automated testing and reconciliation frameworks, and collaborate closely with quant developers and the Historical Data Store team.

What are we looking for?

• Programming: Expert-level in at least one of Python, C++, or Java/Scala, with strong Python regardless (the analytics ecosystem is Python-centric).
• Distributed/large-scale compute: Experience building or operating high-throughput calculation platforms — grid computing, Spark/Dask/Ray, or in-house distributed batch frameworks; profiling and optimising numerical workloads.
• Risk domain: Working knowledge of market risk measures — VaR (historical simulation in particular), P&L vectors, scenario shocks (absolute/relative/log returns), aggregation and netting.
• Data engineering fundamentals: Handling large time-series and position datasets efficiently (columnar formats, partitioning, memory management).
• Engineering practice: CI/CD, automated testing of numerical code (tolerance-based comparison, golden datasets), code review culture.

Nice to have: 

• Experience with HPL/RTPL production and PLA testing.
• Numerical computing depth: numpy/scipy internals, vectorisation, GPU acceleration.
• Experience integrating with quant pricing libraries via C++/Python bindings.

What we offer:

• Competitive compensation depending on experience and skills.
• Regular assessments and salary reviews.
• Paid personal days.
• Mental health support program.
• Language classes.
• Flexible working schedule.

We are looking for a Python Engineer with experience in Machine Learning and Large Language Models to join a short-term project focused on building an intelligent data matching solution.

The project involves developing a reusable tool that automatically matches parent and child records between Excel/CSV datasets using a combination of rule-based logic, semantic search, and AI-assisted approaches. The solution should be configurable, scalable, and capable of handling new datasets without changes to the core business logic.

Project details:
Engagement: Full-time for approximately 2 weeks, followed by several iterations of improvements based on client feedback (with a possibility to continue in the next project phase).
Start date: ASAP.

Responsibilities:

• Develop a reusable Python-based tool for parent-child matching between Excel/CSV datasets.
• Design configurable data processing pipelines that can be executed locally on the client's environment.
• Implement text, code, numeric value, unit, and attribute normalization.
• Build candidate retrieval using exact matching, fuzzy matching, and multilingual semantic search.
• Develop confidence scoring and validation logic to avoid incorrect matches based solely on textual similarity.
• Generate structured output (CSV/XLSX) including match confidence, status, and explanation.
• Participate in several improvement iterations based on results from previously unseen client datasets.

• Communicate with the client regarding edge cases and continuously improve the matching quality.

   

  Requirements:

• Strong commercial experience with Python.
• Experience building Machine Learning or NLP solutions.
• Hands-on experience working with LLMs.
• Experience with semantic search, embeddings, or retrieval systems.
• Familiarity with fuzzy matching techniques and text preprocessing.
• Experience working with structured datasets (CSV, Excel, pandas).
• Ability to design configurable, reusable software rather than one-off scripts.
• Strong analytical and problem-solving skills.
• Good English level for communication.
  
  Nice to have:
• Experience with multilingual NLP.
• Knowledge of vector databases or embedding-based retrieval.
• Experience integrating AI services as fallback mechanisms.
• Experience designing configurable CLI/data-processing tools.
  
  What we offer:
• Short-term, high-impact AI/ML project with the possibility of extension.
• Flexible remote collaboration.
• Opportunity to work on an interesting real-world data matching problem combining ML, LLMs, and traditional search techniques.
• Direct communication with the client and the ability to influence the final solution.
• Competitive hourly compensation based on your experience.

Data Automation: Automate the ingestion of testing component results into the Jira hierarchy and extract data for external reporting.
System Administration & Operations

Instance Management: Oversee the daily health, performance, and configuration of the production Jira instance.

Configuration: Manage complex customizations including workflows, screens, fields, permission schemes, and notification schemes.

Plugin Management: Install, configure, test, and manage the lifecycle of Atlassian marketplace apps.

Access Control: Handle user permissions, project access requests, and license management.

Project Delivery & Stakeholder Management

Requirements Gathering: Interact with business and technical stakeholders to finalize requirements, obtain sign-off, and translate business needs into technical Jira implementations.

Agile Delivery: Track project progress, manage escalations, and ensure functionality is delivered within cost and timeline constraints.

Qualifications & Technical Skills

Scripting & Languages: Expert-level proficiency in Groovy (for Jira backend) and Python (for external automation/scripting).
Jira Development: Extensive experience with ScriptRunner for Jira, including developing custom listeners, behaviours, and workflow post-functions.
Jira Administration: 3+ years of experience managing Jira and Confluence (Server/Data Center or Cloud).
Testing Lifecycle: Deep understanding of Software End-to-End (E2E) testing processes and Test Driven Development (TDD).
Hierarchy Tools: Proficiency with Jira Structure (ALM Works) or similar hierarchy management tools.
Integration: Experience integrating Jira with DevOps tools, specifically Jenkins.
Database: Experience working with databases for data extraction and reporting.

Soft Skills

Problem Solving: Ability to simplify complex technical issues into understandable solutions for non-technical stakeholders.
Ownership: Strong history of taking ownership of the instance health and the user experience; ability to prioritize workload autonomously.
Communication: Excellent verbal and written communication skills for documentation and stakeholder presentations.

Preferred (Bonus) Qualifications

Certifications: Atlassian Certified Professional (ACP-100/ACP-600).
Additional Tools: Experience with Jama software or TestRail.
DevOps: Strong DevOps background.

Education
B.S. or higher in Computer Science, Engineering, or a related technical discipline.
