Software Engineer, Backend

Mployee.me; Delhi; Presencial; INR 1.200.000 - 2.200.000; Jornada completa

Descripción de la vacante

Mployee.me is seeking a backend engineer to help build and extend our backend roadmap, turning identity, device and session signals into trust scores, actions and clear reasons, with guidance from senior engineers.

Day-to-day work includes building API endpoints, validating events, implementing fraud rules, extending SDKs, reproducing errors with sample requests, and writing unit tests while participating in code reviews.

Formación

• Proficient in Python, Go or Rust with HTTP/REST/JSON and basic SQL.
• Strong data structures and algorithms; readable, debuggable code.
• Experience with Git and Linux; willingness to learn from feedback.
• Interest in security and fraud prevention; curiosity about attackers abuse systems.
• Familiarity with agentic AI coding tools.

Responsabilidades

• Build API endpoints and validate device, identity and session events; handle missing or malformed fields and keep signal records consistent for downstream scoring.
• Implement and test guided fraud rules, such as new-device checks and unusual activity velocity; return reason codes that explain why a rule affected the decision.
• Extend signed SDK and business APIs with senior guidance, adding request validation and access checks while keeping each customer's data isolated across requests and sessions.
• Reproduce SDK integration errors using sample requests, logs and metrics; work with SDK engineers to resolve event-format mismatches and document the expected API behaviour.
• Write unit tests for valid, invalid and boundary cases, participate in code reviews, and follow fixes through testing and release monitoring with the team.

The role

Help build and extend Our backend roadmap, turning identity, device and session signals into trust scores, actions and clear reasons, with guidance from senior engineers.

Day-to-day work

• Build API endpoints and validate incoming device, identity and session events; handle missing or malformed fields and keep signal records consistent for downstream scoring. Follow contracts agreed with senior engineers.
• Implement and test guided fraud rules, such as new-device checks and unusual activity velocity; return reason codes that explain why a rule affected the decision.
• Extend signed SDK and business APIs with senior guidance, adding request validation and access checks while keeping each customer's data isolated across requests and sessions.
• Reproduce SDK integration errors using sample requests, logs and metrics; work with SDK engineers to resolve event-format mismatches and document the expected API behaviour.
• Write unit tests for valid, invalid and boundary cases, participate in code reviews, and follow fixes through testing and release monitoring with the team.

What you bring

• Working knowledge of Python, Go or Rust, plus HTTP, REST, JSON and basic SQL.
• Data structures and algorithms fundamentals, with readable code and practical debugging skills.
• Comfort with Git, Linux and learning through feedback in code reviews.
• Interest in security and fraud prevention; curiosity about how attackers abuse systems.
• Proficiency with agentic AI coding tools, with the ability to review, test and take ownership of generated code.

Good to have

• Exposure to PostgreSQL, Redis, queues, Docker or request signing; a backend project, open-source contribution or CTF experience you can explain.
