Data scientist jobs in Kolkata

About the Client

We are a fast-growing Managed Service Provider (MSP) serving complex, high-demand environments. We’re investing heavily in  automation, reporting, and internal products to:

· Eliminate repetitive manual work

· Give leadership accurate, real-time visibility through data and dashboards

· Build internal platforms that become core to how we operate and scale

You won’t be “just a developer.” You’ll be a partner in designing how the business works.

About the Role

We are looking for a Senior Full-Stack Developer (Python-first)  with a consultant mentality—someone who can sit with stakeholders,  understand the business problem, challenge assumptions, design a solution, and then actually build it.

You’ll sit in our DevOps /  Internal Products team and focus on automation, data pipelines, and internal applications that make our teams and clients more effective.  You’ll act as an internal consultant + builder: framing problems,  proposing options, and delivering working solutions.

If you  enjoy asking “why,” mapping out the real need, and then shipping tools  and automations that create measurable impact, this role is for you.

Responsibilities

• You will take business problems from idea → design → implementation → iteration
  
  1. 1. Internal Applications & Tools
• · Design and build internal apps that improve client management, service delivery, and operations/back-office workflows.
• · Implement back-end services (primarily in Python) and practical front-end experiences.
• · Integrate multiple systems (internal tools, third-party SaaS, line-of-business apps).
  
  2. 2. Data Pipelines & Reporting
• · Build and maintain ETL/ELT pipelines to ingest, transform, and model data from multiple systems.
• · Design data models that support reporting and analytics for leadership, account management, and finance.
• · Work closely with BI/reporting tools (e.g. Power BI or similar) to ensure data is accurate, documented, and usable.
  
  3. 3. Automation & Workflow Optimization
• · Identify repetitive, error-prone processes and own their automation end-to-end.
• · Connect APIs, data sources, and internal tools to reduce manual effort and errors.
• · Track and communicate the impact of your work (time saved, errors reduced, faster cycles, etc.).
  
  4. 4. Consultative Stakeholder Collaboration
• · Act as an internal consultant to operations, finance, service, and leadership.
• · Ask probing questions to clarify goals, constraints, and tradeoffs before jumping into code.
• · Translate business pain points into clear technical options (“Option A vs B vs C”) and help stakeholders choose.
• · Push back thoughtfully when a proposed solution isn’t optimal, and recommend simpler or higher-impact alternatives.
• · Communicate progress, risks, and impact in clear, non-technical language.
  
  5. 5. Architecture & Technical Direction
• · Contribute to patterns, standards, and best practices for internal tools and automation.
• · Help make decisions on tech stack, structure, and long-term maintainability.
• · Participate in code reviews and mentoring for other developers where appropriate.

Qualifications

• Strong professional experience with Python (services, scripts, automation, data processing).
• Strong SQL skills and experience with data modeling, ETL/ELT, and working with structured data.
• Experience building APIs, back-end services, or internal tools that support real users.
• Hands-on experience integrating with RESTful APIs and third-party platforms.
• Familiarity with Git and modern development workflows.
• Consultant Mindset & Ways of Working (Must-Have)
  · You think and act like a consultant, not an order-taker.
  · Comfortable sitting with non-technical stakeholders, understanding their world, and reframing the problem.
  · Regularly ask, “What are we really trying to achieve?” before deciding how to build.
  · Can explain technical options in plain business language, including tradeoffs (time, risk, complexity, impact).
  · Strong ownership mindset—you don’t just design the solution, you drive it through to done.
  · Measure success in business outcomes (time saved, fewer errors, better visibility), not just completed tickets.

• Remote only, full-time dedication (40 hours/week)
