This is a mission-critical, hands-on role. Stock broking operations run on tight regulatory timelines — market open, T+1 settlement, end-of-day reporting. Downtime is not an option. We need someone who fixes problems, not someone who escalates them.

About The Role Stellaredge runs a technology-first brokerage. Every client order, every payout, every compliance report, every reconciliation — all of it depends on stable, performant infrastructure.

This role owns that infrastructure: networks, servers, trading applications, and the monitoring systems that keep everything observable. You will be the first responder when something breaks at 9:14 AM during market hours. You will be the person who ensures the OMS is up before 9:00 AM. You will be the one who knows exactly what is running, where it is running, and what to do when it is not. This is not a helpdesk role. It is a technical ownership role with real operational stakes.

What Makes This Role

Different in a Broking Workplace Market hours are fixed — 9:15 AM to 3:30 PM. Any infrastructure failure during this window has direct financial and regulatory consequences. Uptime is not an SLA metric here, it is a compliance requirement.

Trading applications (OMS, RMS) have strict latency and availability requirements set by exchanges and SEBI — standard IT support thinking is insufficient.

End-of-day processes (settlement files, reconciliation uploads, CDSL/NSDL submissions) have hard cutoff times. A server delay at 6 PM can cascade into a regulatory breach.

You will work alongside compliance, DP operations, and finance teams — understanding what their applications actually do operationally is part of doing this job well.

Conduct periodic vulnerability assessments and maintain audit trails for access and configuration changes

Manage SSL certificates, domain renewals, and DNS configurations

Prepare IT infrastructure reports for internal audits and SEBI/exchange inspections

Maintain an up-to-date IT asset register and network topology document Requirements Must Have 2-5 years of hands-on IT infrastructure experience — servers, networks, and application support

Windows Server administration: Active Directory, Group Policy, DNS, DHCP, IIS

Networking fundamentals: TCP/IP, VLANs, routing, firewall rules, VPN configuration

CTCL/IBAPI setup and NSE/BSE connectivity management

Cloud administration: AWS EC2/RDS/S3 or Azure VM/storage basics

Virtualisation: VMware ESXi or Hyper-V administration

CCNA or equivalent networking certification

Experience with monitoring tools: Nagios, Zabbix, Grafana, or PRTG Education B.E. / B.Tech in Computer Science, IT, or Electronics — preferred

BCA / MCA / B.Sc (IT/CS) with strong hands-on infrastructure experience accepted

CCNA, MCSA, RHCSA, or equivalent certifications are a significant positive signal

Graduates from Surat-based engineering colleges (SVNIT, Nirma, DPIAICT, VGEC) are specifically encouraged to apply What We Evaluate Green Flags Has worked in a time-critical environment — bank, broker, exchange, or any firm where downtime has immediate business consequences

Can describe a specific network or server incident they resolved under pressure — what failed, how they diagnosed it, and how long it took

Thinks in redundancy and fallback — always asks 'what happens if this goes down?'

Comfortable with command line on both Windows and Linux — doesn't rely only on GUIs

Has set up monitoring before, not just responded to alerts someone else configured

Understands the difference between a trading application and a regular business application in terms of availability requirements

CCNA or server certification achieved through actual study, not just exam dumps Red Flags Only has helpdesk or desktop support experience — no server or network ownership

Cannot explain a basic network topology or describe what a VLAN does

Escalates everything — no evidence of independent problem resolution

Has never worked under time pressure; treats all incidents as equal priority

Cannot read a server log or interpret a traceroute / ping output to diagnose a network issue

No documentation discipline — has never maintained a network diagram or IT asset register

Treats this as a 9-to-5 role — trading support has irregular hours around market events Interview Process We evaluate for real hands-on ability.

Certifications matter less than demonstrated competence. The process is practical and direct. Round 1 — Async written screening: 3 scenario-based questions — a network issue, a server crash, and a trading application failure (48-hr turnaround; how you think matters as much as the answer)

Round 2 — 45-min technical interview with IT Lead or Founder: deep-dive on past infrastructure work, tools used, incidents handled — bring specifics

Round 3 — Practical assessment (in-person): hands-on diagnostic exercise — you will be given a network/server scenario and asked to work through it live

Round 4 — 20-min final conversation with Operations Lead or Founder: work style, reliability, long-term alignment
