Modern applicant tracking software from Structr supports you in applicant management and in creating, approving and publishing job profiles. It helps to increase recruiting efficiency, simplify processes for HR staff and improve the candidate experience.
Below, we describe custom applicant tracking system development in detail and cover typical use cases, features and benefits.
Custom applicant tracking system development
We offer custom applicant tracking system development that delivers tailor-made software for applicant management. An ATS developed with Structr comes with a powerful Neo4j graph database that enables fast, data-driven HR decisions, a low-code UI builder and AI support for greater efficiency in development and recruiting.
A Structr ATS is a central and flexible recruiting solution that, unlike rigid off-the-shelf software (COTS), makes highly complex data structures and individual workflows easy to manage.
Automated workflows built with Structr for candidate communication, CV parsing with optical character recognition (OCR), feedback loops from specialist departments and interview scheduling drastically reduce administrative effort. Time-to-hire is noticeably shortened, and you secure the best talent ahead of the competition.

Applicant tracking software developed with Structr is based on a Neo4j graph database that enables fast and complex database queries. Multi-layered skill matrices can be mapped with high performance in the graph data model. Unlike graph databases, relational SQL databases often reach their performance limits as complexity grows.
A custom Structr ATS stands out for its high agility. With the low-code UI builder, frontends, HR dashboards and candidate portals can easily be adapted to your requirements. If, for example, new applicant attributes and corresponding new fields are needed, this change to the data structure can be made within seconds while the system is running.
The AI integrated into Structr enables secure, deterministic structured coding and prevents uncontrolled vibe coding. The AI translates requirements into verifiable conditions, which are transferred into the graph in an auditable way.
Applicant tracking system features
The most important applicant tracking system features are creating and managing job ads, managing applicant data and improving the candidate experience.
The following list explains the most important features of applicant tracking systems.
-
Creates and manages job ads
A modern applicant tracking system creates and manages job ads. The ATS enables HR teams to create job ads centrally, format them in the company's corporate design and manage them. Structr generates REST APIs that enable multi-channel posting of job ads on social media, external job boards and the company's careers page.
-
Manages, stores and filters all applicant data centrally in one solution
An ATS manages, stores and filters all applicant data centrally in one solution. The system acts as a reliable single source of truth. All application information, such as CVs, cover letters, portfolios and references, is bundled centrally. The Neo4j graph database in Structr enables recruiters to apply highly complex filters (for example specific programming languages, language skills or work experience). The system links all applicant data intelligently and in a machine-readable way.
-
Improves the candidate experience
A high-quality ATS improves the candidate experience through automated communication. The ATS ensures a straightforward application intake and guarantees fast response times. For example, it allows confirmations of receipt or rejections to be sent automatically.
-
Offers AI-powered tools to make the recruiting process more efficient
A Structr ATS offers AI-powered tools to make the recruiting process more efficient. AI calls can be integrated natively into every single step of the application process, for example for automated pre-qualification or for generating interview questions. With Structr Companion, you can describe the desired data structures and features of the applicant tracking system by prompt. The AI builds the application in compliance with Structr's guidelines. If necessary, the application can afterwards be edited by professional developers in pro mode in the Structr backend.
-
Tracking applications to speed up the hiring process
An ATS makes it possible to track applications in order to speed up the hiring process. Via visual Kanban boards and dashboards, recruiters see in real time which phase a candidate is in (for example screening, first interview or contract offer). Structr's native BPMN process engine orchestrates the entire workflow. Thanks to the graph database, Structr offers a high-performance system that retrieves even deeply nested records within a few seconds.
Applicant tracking system use cases
Typical use cases for applicant tracking systems are job postings, applicant management, recruiting processes and HR reporting.
The following list gives an overview of the most important ATS use cases.
-
Job postings
Companies frequently use applicant tracking systems for job postings. An ATS acts as a central hub for multiposting. Job ads can be published on your company's own careers page, on social networks and on numerous job boards. Structr automatically generates REST APIs for smooth data transfer to external platforms. With automated APIs for your applicant tracking software, you save time and your employer branding stays consistent.
-
Applicant management
An applicant tracking system is used for applicant management to bring all applicant information together in one place. Applications arrive through various channels. A modern ATS ensures that all information is collected clearly in a single system. This eliminates the tedious search through email inboxes. CV parsing and OCR technology make it possible to prepare applicant data in a machine-readable form and make decisions quickly.
-
Recruiting processes
Applicant tracking software is used for recruiting processes. Every company designs its own recruiting processes. A tailor-made ATS improves recruiting processes and promotes collaborative hiring. The native BPMN process engine allows workflows to be mapped precisely. For example, the HR department reviews the documents, forwards them to the specialist departments and collects internal feedback directly in the ATS. The software then automatically sends interview invitations to the relevant candidates.
-
HR reporting
An ATS is used in HR reporting to optimise recruiting strategies in the long term. HR managers need transparent and reliable data. Applicant tracking software developed by Structr analyses key KPIs such as time-to-hire, cost-per-hire and job channel performance in real time. The Neo4j graph database links complex data relationships with high performance, so HR managers benefit from well-founded, data-driven insights.

-
Integrated digital applicant file via DAM with optical character recognition
A Structr ATS ensures reliable and fast recruiting processes through an integrated digital applicant file via a DAM (digital asset management). The DAM features optical character recognition (OCR), which makes uploaded CVs and references machine-readable and fully searchable. The native graph database in Structr translates the extracted information into structured data nodes, enabling lightning-fast semantic searches for specific qualifications, such as programming skills or completed training courses.
-
Seamless process automation in recruiting
Structr applicant tracking software enables seamless process automation in recruiting. Structr integrates a native BPMN-compatible process engine. The application process can be modelled visually as a BPMN diagram. Multi-stage selection procedures, the assignment of trial tasks and the collection of internal feedback are mapped as an automated workflow. The system can be programmed to manage deadlines on its own, so that promising candidates are not put off by long waiting times.
-
BSI-audited data security
Structr has been audited by the German Federal Office for Information Security (BSI) and is therefore suitable for the public sector. Our software offers fine-grained rights management and stands out for its open-source approach. You can run your ATS yourself on your own servers or have us host it in a secure cloud within the EU. Structr thus supports you in complying with the GDPR and effectively protects you against access under foreign cloud laws (US CLOUD Act).
-
Automatic email and interface integration for job portals
A Structr-based applicant tracking system automates email and interface integration for job portals. A job ad is usually published on various channels to maximise its reach. Structr automatically generates REST APIs. Thanks to the automatically generated APIs, the ATS can be seamlessly connected to job boards such as Indeed or StepStone and to your existing HRMS. The system handles email communication with applicants, for example by sending confirmations of receipt or automatically scheduling interviews and sending invitations.
Applicant tracking system development process at Structr
Applicant tracking system development at Structr is divided into 4 steps: consultation, prototype development, a workshop and, on request, hosting and support.
In the following list, we explain all 4 steps of developing a custom applicant tracking system with Structr.
-
1
Detailed consultation on the development of your custom applicant tracking system
Before developing your custom applicant tracking system, we hold a detailed consultation with you. In the consultation, we gain a fundamental understanding of your recruiting processes so that we can tailor the prototype precisely to your individual requirements. We capture your specific candidate journey, your selection procedures and your employer branding goals. In addition to discussing the application processes, we clarify which existing platforms need to be connected via interfaces. On this basis, we create an initial draft of the system architecture that maps your applicant management requirements exactly.
-
2
ATS prototype development
Our ATS prototype development is usually completed within 1–3 working days. Thanks to the integrated low-code UI builder, controlled AI support and the powerful Neo4j graph database, you receive a working ATS prototype within a few days. The prototype offers real functionality, including the database structure, fully automatically generated REST APIs and a fine-grained permission concept for sensitive applicant data.
-
3
Workshop on your Structr applicant tracking system
Once we have developed your prototype, you test it directly with us in an interactive workshop. Your recruiters and HR managers try out the ATS with real use cases from everyday HR work, for example receiving an application or scheduling interviews. We collect your feedback directly and implement it in the system straight away. Adjustments to workflows or the user interface can be made immediately in the running system. This helps you achieve high user acceptance when introducing the system.
-
4
Hosting and long-term support
On request, we take care of hosting and long-term support for your custom applicant tracking system. Applicant data is highly sensitive and requires strict compliance with the GDPR. We give you the greatest possible flexibility in hosting: we host your ATS securely in the cloud on servers within the EU, or you run it on-premises on your own IT infrastructure. We offer service level agreements (SLAs) with guaranteed availability and included developer days.
How much does a custom applicant tracking system cost?
Structr usually offers an applicant tracking system prototype at a fixed price of between EUR 5,000 and EUR 15,000. The cost of the complete applicant tracking system depends on the complexity of the data structures and the system requirements.
