7 days ago
Location:
Navi Mumbai (Vashi)
Employment Type:
Full-time
Reports to:
VP – R&D
Role Summary
We're hiring a Lead QA Engineer with deep hands-on experience in
IP networking, protocol behavior, and Deep Packet Inspection (DPI)
. You'll own test design and execution for network appliances/services, verify protocol compliance, analyze pcaps, and drive performance/scale validation (throughput, latency, jitter, loss).
What You'll Do
- Design, author, and execute
manual and automated
test cases for L2/L3/L4–L7 features and DPI classification engines. - Validate core protocols:
TCP, UDP, HTTP/HTTPS, FTP, DNS, DHCP, SIP, ICMP
(plus negative/edge scenarios: retransmissions, fragmentation, timeouts, MTU/MSS, packet reordering). - Perform
Deep Packet Inspection
tests for signature accuracy, false-positive/negative rates, and protocol/APP identification. - Build and run
performance/scale
tests (throughput, CPS/SPS, concurrent sessions, latency/jitter/loss) using traffic generators. - Capture and analyze traffic with
tcpdump/Wireshark/tshark
; create precise
capture/display filters
, annotate traces, and file actionable defects with MRE steps and RFC references. - Automate routine/system tests using
Python/Bash
(e.g., scapy/pytest) and integrate with CI where practical. - Maintain lab setups: switches/routers/firewalls/network appliances; manage images, configs, topologies, and golden baselines.
- Collaborate with Dev/PM/SRE on test strategy, coverage, and release criteria; contribute to
test plans, exit reports,
and risk assessments. - Ensure compliance with relevant
RFCs/industry standards
; document test evidence.
Must-Have Qualifications
- 6–9 years
in QA for
networking/telecom products
(not web/app UI testing). - Strong grasp of
OSI model, L2/L3
, IPv4/IPv6, VLANs, NAT, routing basics; deep
TCP
internals (state machine, handshake, retransmission, flow/congestion control). - Practical DPI knowledge: signatures/classifiers, payload parsing, evasion/obfuscation scenarios.
- Tools:
Wireshark, tcpdump/tshark, iperf
, and at least one traffic generator (
Ixia/Keysight, Spirent
, or equivalent). - Comfortable on
Linux
(iproute2, systemd, networking namespaces), shell scripting, and
Python
for test automation/log parsing/pcap handling. - Experience with
Git
, issue trackers (e.g.,
Jira
), and test management. - Excellent defect reporting and communication skills.
Nice to Have
- Knowledge of
firewalls/VPN/QoS/load balancers
and security protocols (IPsec/TLS). - CI/CD and container networking (Docker/K8s), Robot/pytest.
- Certifications:
CCNA/CCNP
,
ISTQB
(or equivalent).
