SENIOR SOFWARE ENGINEER (FULL STACK)
Check out The Global Talent Co.’s talent network: https://www.globaltalent.co/network
The Role
- You will join a company building the digital infrastructure for grant funding, helping organizations spend less time navigating funding logic, forms, and administration and more time on the projects and impact that matter.
- The platform brings together research across 18,000+ funding programmes, AI-supported analysis and application drafting, expert review, and ongoing grant management. AI handles what can scale, while people bring experience and judgement where it matters.
- As a Senior Software Engineer, you will work end-to-end on AntragPlus, contributing across the backend, frontend, infrastructure, and AI pipeline at the core of the platform.
- You will be one of the company's first engineering hires, with significant ownership over technical decisions, engineering standards, architecture, and the product itself.
- You will own problems from the initial conversation with the grant team through to production, rather than simply working from predefined tickets.
Position: Senior Software Engineer (Full Stack)
- Seeking a highly autonomous Senior Software Engineer with strong full-stack experience who can build and ship product features end-to-end while contributing deeply to AI pipelines, infrastructure, production systems, and technical architecture.
- The ideal candidate combines strong technical depth with a high-ownership mindset, a usability-first approach, and the ability to identify and solve problems independently in an environment where not everything is fully defined yet.
Responsibilities
Product Development & Full-Stack Engineering
- Build and ship end-to-end product features independently, including the user interface.
- Work confidently across the frontend, backend, infrastructure, and AI pipeline.
- Build from real user problems by working closely with the grant team, rather than simply implementing predefined tickets.
- Develop interfaces with a usability-first mindset, ensuring the product genuinely works for grant writers.
- Take ownership of problems from initial discovery through to production deployment.
- Contribute to reducing the time from starting a new project to a finished, submitted application through product improvements, automation, and better workflows.
AI Development & Evaluation
- Advance the platform's AI capabilities through prompt engineering, context management, cost control, and multi-provider AI setups.
- Work with AI providers including AWS Bedrock, Anthropic, and OpenAI.
- Build and operate AI pipelines in production, going beyond simply calling an API.
- Develop and own the company's AI evaluation practice, including prompt quality, model selection, and regression detection.
- Work with AI agents and tool-calling workflows where applicable.
- Use AI-native development tools such as Claude Code or Cursor as part of your engineering workflow.

Engineering Architecture & Technical Leadership
- Shape the company's technical architecture, code quality, engineering standards, and technical roadmap.
- Help establish how the engineering team works and the technical standards it follows.
- Identify better technical solutions proactively rather than waiting for predefined tasks.
- Take complete ownership of technical problems and drive them through to resolution.
- Contribute to building scalable technical foundations as one of the company's first engineering hires.

- High level of autonomy and ownership, with the ability to identify problems, develop solutions, and close the loop without hand-holding.
- Usability-first mindset, with the ability to build interfaces that genuinely work for end users.
- Comfortable working in an environment where not everything is fully defined and where engineers are expected to proactively shape solutions.
