Fullstack Engineer (.NET & Angular) with Data & AI expertise

Sunscrapers is an AI-native data and technology partner for private equity, venture capital, and healthcare. We build proprietary data infrastructure, deploy AI solutions, and own the outcomes — not just the code. Our clients manage a cumulative $210B+ in assets and stay with us for an average of five years. We've reorganized our own company around AI, and we do the same for the firms that trust us with their most critical decisions.

The project:

The primary role of the Fullstack Data & AI Engineer is to build and maintain software applications using .NET/C# and Angular, while also designing and supporting data pipelines and AI-powered features. The person will create applications from scratch as well as modify existing ones, including configuration, testing, and deployment. Beyond application development, you will work with cloud data warehouses, ETL processes, and LLM integrations to deliver end-to-end solutions. You will also provide application support and mentor junior team members.

On a daily basis, you will write and debug code, work with large datasets, and collaborate with software engineers, QA analysts, product managers, business analysts, and production support engineers to build software solutions that meet client business needs.

The role:

Write clean, scalable, and secure code using T-SQL and .NET/C# for applications hosted on-prem and in Azure
Develop front-end and back-end components using Angular, .NET Core, C#, T-SQL, JavaScript, Message Queues, and related technologies
Design, implement, and maintain data pipelines and ETL/ELT processes, including ingestion, transformation, and loading into cloud data warehouses such as Redshift or BigQuery
Build and maintain efficient database schemas, stored procedures, and queries using SQL Server; optimize queries and application code for performance and stability
Integrate LLM-based features and AI tools into applications and development workflows
Revise, update, refactor, and debug code to troubleshoot errors and improve quality
Follow Agile methodology and participate in team ceremonies (Standup, Retro, Planning, Refinement, etc.)
Participate in requirements analysis and refinement, updating requirements as needed
Produce and execute unit tests
Participate in code reviews and both provide and incorporate feedback
Collaborate with internal teams to produce and document scalable software design and architecture
Contribute to improving development processes, engineering tools, code quality, automation, and the SDLC
Serve as a technical expert on applications and provide Level 2/3 support via Helpdesk tickets as needed

What's important for us?

Bachelor's degree in Computer Science, Information Systems, or a related field, or equivalent experience
At least 6 years of .NET/C# and T-SQL full-stack development experience, including C#, ASP.NET, SQL Server (T-SQL), REST, Angular, and Entity Framework
Hands-on experience with cloud data warehouses such as Redshift, BigQuery, Snowflake, or Azure Synapse, including designing schemas, writing complex queries, and managing large datasets
Practical experience building and maintaining data pipelines and ETL/ELT processes
AI-forward mindset with practical experience using LLMs and AI tools to improve development workflows and application capabilities
2+ years of experience developing and supporting applications hosted in Azure
Good understanding of secure coding guidelines and the ability to apply them in practice
Experience working with Healthcare EDI transactions is a plus; 1-2 years of Healthcare or Insurance industry experience is a plus
Strong analytical, critical thinking, and problem-solving skills, combined with solid interpersonal and communication skills
High attention to detail; able to organize and prioritize work while maintaining accuracy
Ability to work independently and follow through on assignments with minimal direction
