ONE (1) research grant for students with BSc degree with reference number BI|2026/880 under the scope of the Projet SALVE: Securing Artificial Language Models Against Vulnerability Encoding (2024.14936.PEX), funded by Fundação para a Ciência e a Tecnologia, is available under the following conditions:OBJECTIVES | FUNCTIONS This task evaluates the impact of controlled code perturbations on the classification stability and robustness of Large Language Models (LLMs) in distinguishing secure from insecure JavaScript code. The student will design and implement a systematic evaluation pipeline to assess model behavior under perturbation-induced variations. The work plan includes: • Evaluation Pipeline Development (Month 1) • Implement a scalable evaluation framework using local LLM infrastructure (e.g., Ollama, LMStudio). • Integrate multiple LLMs for comparative evaluation. • Automate classification experiments across original and perturbed datasets. • Classification Shift Analysis (Month 2) • Measure classification changes between original and perturbed code variants. • Identify perturbations that cause label flips (secure ↔ insecure). • Quantify: Misclassification rate, Stability rate, False positive rate, False negative rate • Robustness Assessment (Month 3-4) • Define robustness metrics for security classification consistency. • Evaluate resilience to obfuscation, control-flow changes, and API variations. • Compare robustness performance across different models. • Misclassification Characterization (Month 4-5) • Construct an augmented misclassification dataset containing: original and perturbed variants, model predictions, correct labels, perturbation type • Analyze patterns in failure cases. • Exploratory Explainability Analysis (Optional) • Investigate whether explainability tools can help identify model reliance on superficial features. • Analyze whether models rely on syntax-level heuristics versus security-relevant semantics.All experimental artifacts, code, and results will be released in an open-source repository. The selected candidate will be integrated into a research team with established expertise in software security, program analysis, and AI-driven code intelligence, with a track record of collaboration with leading technology companies and publications in top-tier international conferences and journals.BINDING LEGISLATION Law 40/2004 of 18th of August (Scientific Research Fellow Status) in its current wording.https://diariodarepublica.pt/dr/legislacao-consolidada/lei/2004-58216179 Regulations for Research Grants of the Foundation for Science and Technology in forcehttps://diariodarepublica.pt/dr/detalhe/regulamento/950-2019-127238533 INESC-ID Lisboa Grant Regulations in forcehttps://www.inesc-id.pt/scholarship-regulations/ The fellowship contract is awarded on an exclusive dedication basis – art. 5 of Scientific Research Fellow Status and art. 16 of Regulations for Research Grants of the Foundation for Science and Technology.DURATIONFIVE (5) months, starting in June 2026, renewable subject to suitable performance within the period of the project, not exceeding the maximum period set by FCT for such grants.RENEWALLRenewable is subject to performance if the candidate is enrolled in a MSc program - art. 6º, n.4 b)https://diariodarepublica.pt/dr/detalhe/regulamento/950-2019-127238533https://files.dre.pt/2s/2019/12/241000000/0009100105.pdfsubject to suitable performance within the period of the project, not exceeding the maximum period set by FCT for such grants – 2 years (included contract renewals) Renewable is subject to performance if the candidate is enrolled in a Non-degree programme – art. 6º, n. 4 a) https://diariodarepublica.pt/dr/detalhe/regulamento/950-2019-127238533https://files.dre.pt/2s/2019/12/241000000/0009100105.pdfsubject to suitable performance within the period of the project, not exceeding the maximum period set by FCT for such grants – 1 year (included contract renewals) MONTHLY AMOUNTThe monthly amount of the grant is 1040.98€ according to the “Regulations for Research Grants of the Foundation for Science and Technology” in force.The payment will be made through a monthly bank transfer to a portuguese bank account, held by the grantee.https://www.fct.pt/wp-content/uploads/2025/02/Tabela_valores_SMM_2025.pdf SCIENTIFIC SUPERVISIONThe activity will be supervised by : • Rui Abreu , Full Professor at FEUP and Researcher at INESC ID. • Sofia Reis, Invited Professor at FEUP .WORKPLACE- INESC ID - Headquarters Rua Alves Redol, 9, 1000-029 Lisboa - INESC-ID - Taguspark Avenida Professor Cavaco Silva, Edifício IST 2744-016 Porto Salvo - INESC-ID Energia IST - Departamento de Engenharia Electrotécnica e de Computadores, Área de Energia, Av.

The members of the evaluation panel assign a classification to each of the candidates on a scale of 0 to 100 points, ranking the candidates according to their classification consisting on the sum of the partial classifications assigned in each evaluation criterion, and considering the weighting factor given to each parameter. In this process abstentions are not allowed. In the event of a tie among candidates with the same highest evaluation score, the Evaluation Panel reserves the right to conduct interviews to have a more objective assessment of specific criteria. If an interview is conducted, the punctuation proposed by the evaluation panel is obtained by assigning a weighting factor of 80% to the CV, and a weighting factor of 20% to the interview. Additionally, the evaluation panel retains the discretion to withhold the scholarship if the candidates fail to fulfil the stipulated requirements.The evaluation panel may also decide not to assign the scholarship, if none of candidates meets the required conditions. If the requirements mentioned above are not fulfilled, the evaluation panel may choose not to select a candidate. Candidates with an average score below 70, are not recommended for hiring Minutes of the evaluation panel meeting are drawn up with a summary of what has taken place in the meeting, as well as the votes emitted by the jury, being available to the candidates whenever requested.EVALUATION PANEL JuryNameProfessional StatusInstitutionsPresidentMiguel Pupo CorreiaResearcher / Full ProfessorINESC-ID / Tecnico, ULisboaMemberNuno SantosResearcher / Associate ProfessorINESC-ID / Tecnico, ULisboaMemberJoão F.
